Introduction

Thank you for purchasing the NextDent 5100 3D Printer.

The NextDent 5100 Printer is a flexible and efficient projector-based 3D-printing system that produces high-fidelity parts from a broad range of biocompatible materials. The NextDent 5100 Printer uses a digital-projection light source and a special membrane-based resin tray that enables very high print speeds and new material chemistries that provide production-grade properties. It is intended to be used as a three-dimensional output device to create (or to communicate design intent of) durable, end-use parts. Parts produced can be used in all phases of design, from a concept build to functional testing and end-use parts. The NextDent 5100 Printer is the ideal printer for dental applications using NextDent resins: Surgical Guide, Crown & Bridge MFH, Ortho IBT, Denture 3D+, Ortho Rigid, Model 2.0, Tray, Gingiva Mask, Cast, and Try-In.

These parts are generated in the rapid prototyping (RP) environment under the control of the printer operators. The system must be run by dental technicians who are trained in proper usage of the printer and resins. All design and process considerations are compatible with an RP environment. The three-dimensional solid parts that are printed consist of different print materials that cure when exposed to 405 nm radiation. The operator pours print material, also called "resin," into the resin tray. Using a proprietary digital projector that 3D Systems has developed, a radiation pattern is cast onto the underside of the resin tray and through to the bottom of the resin. This radiation causes a phase change in the resin that converts it into a solid polymer, adhering to the print platform. After a layer has cured, the elevator moves the print platform up by one layer length and the radiation pattern for the next layer is projected. This process repeats, layer by layer, until the build file is complete. The print platform, along with the part, is removed from the printer and the part is cleaned and post-cured to provide a finished part.

This manual provides users with an understanding of features, system requirements, and operating procedures needed to create finished parts using the NextDent 5100 Printer.

Environmental Safety

The following are environmental issues concerning the NextDent 5100 Printer:

  • Controlling waste heat is not required for normal operation of the NextDent 5100 Printer.
  • When you dispose of print materials, refer to the SDS for that material and follow any applicable local, state, and federal regulations.
  • All waste products (spilled print material, cleaning solvents, etc.) must be disposed of in accordance with all applicable local, state, and federal regulations.
  • Do not clean anything with uncured resin on it in a sink or tub that drains into normal wastewater.

Safety Switches

There are three safety switches on the printer, located on: the lid, the front door, and the catch tray. Tripping or defeating any of these switches will abort the current print job and freeze the elevator. The next time you send a job to the printer, the elevator will move back to the home position before printing. Please see the section Abort a Print Job for more information.

Material Handling and Safety

NOTE: For complete safety information and instructions for use, please read the SDS and Instructions for Use for the NextDent resin you are using. These documents are packaged in with each bottle of print material.

HARMFUL IRRITANT WARNING: Always wear chemical-resistant gloves (such as nitrile gloves), goggles, and protective clothing when handling print material. Avoid skin contact. Avoid breathing in print material fumes.

  • Always practice standard dental-lab hygiene and follow Personal Protective Equipment (PPE) requirements outlined in this manual.
  • safety glassessafety glovesAlways wear chemical-resistant gloves, such as nitrile, when working near print materials or with partially cured parts. It is recommended to wear approved goggles and protective clothing. Protective clothing includes, but is not limited to: closed-toed shoes, full-length pants, and splash-resistant lab coats or equivalents. 3D Systems recommends using 100% nitrile gloves; however, other chemical-resistant gloves will suffice. Do NOT use latex gloves, as they do not provide complete chemical protection.
  • Wearing contact lenses when working with print materials is not recommended.
  • Avoid breathing in vapors from print material. To avoid breathing in vapors: when opening the build chamber, allow a few seconds to pass before putting your face near the opening. No special facility and/or ventilation modifications should be required to operate the printer in a lab environment.
  • Always wash skin thoroughly with a nonabrasive soap and COLD water after working with print materials. DO NOT USE HOT WATER OR SOLVENTS to wash hands, as these will stimulate your pores and result in absorption through the skin. Print material is sensitizing and can cause bad allergic reactions if absorbed through the skin. A person who becomes sensitized to print material should not work around that material in the future.
  • If a small amount of resin gets on your clothing, remove the article of clothing as soon as possible (it might be a good idea to have a change of clothes on hand just in case). Have contaminated clothing dry cleaned. DO NOT wash in regular washing machine that drains into wastewater. If a particularly large amount of resin gets on your clothes, it is best to discard them according to all local, state, and federal regulations. Keep contaminated clothing away from food and drinks. Wash hands thoroughly after handling contaminated clothes, even if you wore protective clothing/gloves to handle them.
  • Use extreme care when handling >90% alcohol solvent, which is used to remove excess print material from uncured parts. >90% alcohol solvent is very flammable.
  • Keep all print materials away from heat, sparks, static discharge, and flame. Print material containers may rupture when exposed to extreme heat. We recommend storing your NextDent materials in a fire-resistant storage cabinet. Please refer to the SDS for a particular resin to view its flash point.
  • High temperatures may cause a spontaneous polymerizing reaction, generating heat and pressure. Closed containers may rupture or explode during a runaway polymerization. Use a water spray or fog to reduce or direct vapors.
  • Fire fighters should use a self-contained breathing apparatus and full protective clothing in the event of a resin fire.
  • Do not leave uncured, or liquid, resins in an area where persons who are not knowledgeable about their handling or use may have access to them.
  • Keep away from food and drinks.

WARNING: Use National Fire Protection Association Class B extinguishers such as carbon dioxide, dry chemical, or foam. A spray of water might also be effective. Do not use a direct jet of water or smothering to extinguish burning resin or solvents.

 

Print Material Characteristics

The photopolymers used in the print materials may be hazardous if handled improperly. Repeated skin contact with print materials may cause sensitization. Consult the manufacturer’s Safety Data Sheet (SDS) for information on specific print materials. For further information on this and related topics, consult the 3D Systems Materials website.

WARNING: Never mix different print materials. doing so will render both materials ineffective.

NextDent Material Storage

Print materials should be stored in the opaque, non-reactive containers in which they were provided, according to the guidelines given in the SDS included with the print material, and according to all applicable regulations (local, state, and federal). Protect print material from sunlight, ambient light, and moisture. Close the resin bottle after each use. Be sure your resin-storage area is dry, dark, and between 5°C-30°C (41°F-86°F). It is preferable to store the resin in a fireproof cabinet. Improperly stored resins may increase in viscosity, and may eventually result in a gelled, polymerized product in the storage container. Materials should be stored in conformance with applicable laws and regulations. The expiration date of the product is mentioned on the product label. If resin is past its expiration date, the product is no longer guaranteed in terms of treatment. 3D Systems is not responsible for losses incurred as the result of improper storage of print material.

Print Material Disposal

Do not dump print material down any drains. Dispose of print material according to the guidelines given in the SDS included with the print material and according to all applicable regulations (local, state, and federal). For more information on print-material disposal, please see the section Considerations for Material in the Chapter: Facility Requirements.

Print-Material Spill Containment

A major print-material spill is unlikely during normal use of the NextDent 5100 Printer. However, there may be certain situations that require containment of a major resin spill. Your company has the responsibility to define what constitutes a major spill. Clean up spilled print material as quickly as possible, as material will cure under both natural and artificial lighting. Personnel who are involved in cleaning up major spills of print material should wear NIOSH/MSHA approved respirators designed for use with organic chemical vapors. In addition, each person should wear protective goggles, rubber boots, and 100% nitrile gloves to minimize exposure to print material, which can cause eye, skin, and respiratory irritation, as well as possible skin allergies and respiratory reactions.

WARNING: Untrained personnel should be evacuated from the area.

WARNING: Print materials are flammable. Care should be taken during print material containment and cleanup operations.

 

A supply of dikes and control booms should be stocked so they are available to contain the affected area in the event of a major print-material spill. The spilled print material should then be absorbed on inert, absorbent material and placed into drums for transfer to an approved waste-disposal site. After absorbing all spilled material, clean the spill location with a nonabrasive cloth and >90% alcohol solvent. After cleaning up the spill, individuals should wash thoroughly with soap and COLD water. Any clothing touched by resin should be dry cleaned before reuse. If resin has gotten onto your skin or clothes, avoid exposure to sunlight or other UV-light sources until skin and clothing have been cleaned of print material. Repeated or prolonged skin contact may cause sensitization. Vapor may be harmful.

Eliminate sources of ignition. Prevent entry into drains. Absorb spilled resin onto sand, earth or any other suitable adsorbent material. DO NOT absorb onto sawdust or other combustible materials. Resin spills or uncontrolled discharges into wastewater systems must be reported to the appropriate regulatory body. Do not discard resin into drains/surface waters/groundwater. Maximize ventilation after accidental release.

Shelf Life

Print materials are certified for use for 24 months from their date of manufacture. The expiration dates are marked on the material bottle labels. Resins should not be used past their expiration date. The printer will not accept the scan of a resin bottle that is expired.

In-Service Life

In-service life of the print material is defined as the useful life of the material after having been poured into the NextDent 5100's resin tray. The in-service life of print material greatly varies depending on material type, usage and environmental conditions. If the material is exposed to temperatures outside of the normal operating limits, is exposed to UV light, is exposed to particulates or vapors in the air such as dust or fumes, or if contaminates are introduced such as partially cured platforms being placed back into the resin tray, this will shorten the material's in-service life. The types of patterns and builds performed also affect the in-service life of the material. With all this taken into consideration, the in-service life of the material is the same as its expiration date: two years. The material retains its usefulness until a buildup of viscosity or a change in reactivity prevents further processing in the NextDent 5100 Printer. All materials require some level of stirring or spinning to retain their properties. You must NOT mix resin from an old resin bottle with resin from a new resin bottle. These resins will be from different batches; and mixing them could render both ineffective. Follow the Instructions for Use of the specific material you are using for complete instructions on getting the most use out of it.

Contamination

Care should be taken when cleaning windows, panels, and other parts of the NextDent 5100 Printer. Cleaning products that contain ammonia should not be used because they can contaminate the material. Instead, use a small amount of >90% alcohol solvent on a paper towel to clean up spills. Accidental contamination of resins may change the material’s performance characteristics to such an extent that acceptable parts can no longer be reliably created.

Polymerization

Polymerization may occur upon heating the resin bottle. Signs of polymerization of stored resin include container bulging, leaking, the emission of heat, or an unusual odor from the container. If you notice any of these traits, do not use the material and dispose of it according to all local, state, and federal regulations.

WARNING: Sealed container may rupture if explosively hot. Please see the resin's sds for information on its flash point.

Electrical Safety

Do not remove any panels or other parts of the printer casing. The printer was designed to minimize operator exposure to electrical hazards during normal operations. All exposed electrical circuits are contained within limited-access cabinets. This is to separate the operator from service and maintenance areas. 100-240VAC power is present in multiple locations throughout the unit. Whenever performing maintenance procedures, power down the machine and unplug AC power if possible.

Emergency Shutdown

NOTE: The NextDent 5100 Printer does NOT have an Emergency Stop button. The only way to stop printer operation during an emergency is by unplugging the power cord from the power inlet on the printer.

First Aid and Protective Equipment

The following paragraphs provide general first-aid procedures and recommendations for protective equipment to minimize the risks from print material exposure. If professional medical attention is necessary, take the Safety Data Sheet (SDS) for the exact print material involved to the attending physician.

Skin Contact

NextDent resin may cause sensitization by skin contact. It is irritating to the skin; repeated and/or prolonged contact may cause dermatitis. Wear 100% nitrile gloves and lab coats to avoid skin contact. Should print material come in contact with skin, wash thoroughly with soap and COLD water and immediately remove contaminated clothing and shoes. If skin is irritated, get medical attention. Dry-clean contaminated clothing. Discard contaminated shoes and leather products.

Eye Contact

High vapor concentration may cause irritation. Safety goggles should be worn to prevent accidental splashes of print material into the eyes. If print material comes in contact with the eye, flush immediately with large amounts of COLD water for 15 minutes. Avoid sunlight, fluorescent light, and other ultraviolet light, and obtain immediate medical attention. Eye-wash facilities and a first-aid kit should be readily available and close to the print material.

Contact Lenses

If print material splashes into the eye when contact lenses are worn, flush the eye with water immediately. Verify that flushing has removed the contact lens from the eye. Protect eyes from light and obtain immediate medical attention. Discard contact lenses that come into contact with liquid print material.

Fume Inhalation

Inhaling fumes from NextDent resin is irritating to the respiratory system. High atmospheric concentrations may lead to irritation of the respiratory tract, dizziness, headache and anesthetic effects. Do not operate the NextDent 5100 Printer without its carbon filter in place. Normal operation of the printer with filter in place should not emit fumes. However, if a person should inhale printer fumes, bring the exposed person to fresh air. Perform CPR if required. If breathing is difficult, give oxygen and obtain immediate medical attention for the person.

Ingestion

Do not induce vomiting. Never induce vomiting or give anything by mouth if the victim is unconscious or having convulsions. Immediately rinse mouth and drink plenty of water. Get medical attention.

Safety Notice

CAUTION: Use of controls or adjustments, or performance of procedures other than those contained in any official manual for this machine, may result in hazardous radiation exposure.

    NOTE: Closed light-projection products are not considered to be hazardous.

 

The NextDent 5100 printer incorporates a protective housing and radiation-protective lid, such that there is no exposure or human access to the radiation generated by the light projector during normal operation. The print engine was evaluated to IEC 62471 and classified as Risk Group 2. This means the UV light is only a moderate risk and does not pose a hazard due to aversion response to bright light or thermal discomfort. However, it is still good practice not to stare directly into the projector, particularly when running the machine with an empty resin tray.

All service to the light-projection process machine, the embedded light-projection system, and other components requiring sensor override shall only be performed by 3D Systems Corporation service personnel, their authorized agents, or personnel who have been service trained by 3D Systems Corporation.

Resin Tray

You will hand-pour resin into the resin tray before printing. The NextDent 5100 Printer works with all NextDent™ print materials, allowing the printer to work for many different dental applications. The NextDent 5100 Printer comes with one resin tray per machine purchased. Purchasing multiple resin trays gives the user the ability to easily print with two different materials on one machine. The more resin trays you have, the more materials you can print with. If the resin tray is sufficiently cleaned in between builds, it is also possible to use a different print material in the same resin tray. However, not every resin can share the same tray, even if the resin tray is cleaned. Please see the section Resin Tray Material Cross-Usage for more information. Determine the number of resin trays you will require.

Part Cleaning

After parts have finished building in the printer, it is necessary to clean them of any uncured resin using an ultrasonic cleaner. You will place the printed part inside a steel or glass container with >90% alcohol solvent. You will then place the container in the ultrasonic cleaner, which will send ultra-sonic sound waves through the solvent to agitate it. As with any solvent, the >90% alcohol solvent will become saturated and rendered ineffective over time. You will need to dispose of the solvent according to local, state, and federal regulations and fill the container(s) with fresh solvent. For more information on cleaning build parts with an ultrasonic cleaner, please see the section Cleaning Parts Using an Ultrasonic Cleaner.

Ultrasonic cleaner. This image is for sample purposes only and is not a recommendation or endorsement of any brand of ultrasonic cleaner.

Part Drying

After cleaning the part(s), it necessary to dry them of any solvent used in the cleaning step. This may be done in several ways, but a few recommended methods follow:

For all parts, be sure there is an absorbent cloth (disposable or otherwise) or container underneath the part to catch the solvent being cleaned off.

  1. Shop air - if you have shop air in your facility, this would be the most-ideal way to air-dry the parts. This is not a replacement for air drying, but will speed up the process. Once finished using compressed air, let the part sit out for 30 minutes to air dry.
blow-dry.jpg
  1. Air Compressor - If you do not have shop air, an air compressor would be the next-best solution. However, be aware that air compressors are fairly loud. This is not a replacement for air drying, but will speed up the process. Once finished using compressed air, let the part sit out for 30 minutes to air dry.

Site Selection - NextDent 5100 Printer

This section provides the requirements and recommendations to determine the most appropriate location for a highly functional, efficient NextDent 5100 Printer workspace, with room for other equipment and supplies. To help you choose a location, the Advance Preparation Checklist provides the attributes that you need to select the best location for your installation. After narrowing the list of possible locations, consider each requirement carefully before making a decision about your final placement site.

Part 1

Space Requirements

User preferences, building codes, and equipment configuration help you to define the total floor area that your NextDent 5100 Printer will need. The NextDent system should be located in an environmentally controlled room. Locate the secondary post processing equipment and supplies in the same room or adjoining room, if possible. The figure below shows an ideal site configuration that minimizes the required movement of parts after part building. The NextDent 5100 Printer Measurements Diagram shows the minimum dimensions of the NextDent 5100 Printer. Your site layout will vary.

 

NOTE: Due to UV safety requirements, the system should be located where access to the room can be avoided during an emergency.

NOTE: The NextDent 5100 Printer should be placed such that the front of the unit is easily accessible for opening the door and loading/unloading print platforms. There should also be at least six inches of clearance on the sides and back of the printer for proper air flow. If you have the pedestal, the outriggers hitting the wall will add the required clearance. You may wish to use an Uninterruptible Power Supply (UPS) to keep your devices running in the event of a power surge/outage.

Other Requirements

The printer runs local DHCP servers for two static local/hardware connections:

  • 192.254.1.100
  • 192.168.7.2

Your network cannot use these IP addresses for one of your printers.

Floor/Area Surface

Floors and counter spaces in the NextDent work area should be non-porous and suitable for cleaning with solvents. The feet of the printer must be on a sturdy, level surface; be sure to make any leveling adjustments needed to the desk/counter your printer will be on. Carpeted floors must not be used. Remove any carpeting or other non-porous flooring where the feet of the NextDent system will be placed. The system should not straddle any floor/desk/counter seams. The maximum permissible platform incline is 2.5 cm/12 m (1 in/40 ft).

Floor Vibration and Shock

The system is a precision mechanical and optical machine that is sensitive to vibration. In order to ensure part quality and accuracy, a ground floor location with a concrete floor, (mininum of 4 inches thick) is recommended.

The NextDent 5100 is slightly self-damping, and should not be affected by normal or incidental environmental vibration; however the area should be isolated, either via location or some other physical or mechanical means, from any significant internal or external vibration sources such as heavy machinery, HVAC and fans. Locations near airports or train tracks which could cause unacceptable shock or vibration levels are not recommended.

Load-Bearing Capacity

The NextDent 5100 Printer is 34.5 kg (76 lbs) and does not require a table rated for a heavy load. Additional equipment, such as a UV oven or ultra-sonic cleaner, will each have their own loads for your setup to bear. Refer to the Weights and Measures Charts to determine the total weight of the equipment to be housed in your room to ensure that you do not exceed the maximum load-bearing capacity that your printer-staging area can support.

Electrical Requirements

Electrical voltage requirements for the NextDent 5100 Printer:

  • 120V, 240V, 50/60 Hz, 4A (2A Europe), 1 phase

Power for the NextDent 5100 Printer should be on a surge-protected circuit. 3D Systems does not require the use of a UPS (Uninterruptible Power Supply) for the NextDent 5100 Printer. However, if you live in an area with frequent power surges/outages, a UPS would be useful. A UPS would prevent a build from crashing in the event of a brief power outage/surge, as it would give you time to properly pause the print job.

Ensure that the space you select for the printer has a power outlet reachable by that length of cord. Use of an extension cord or power strip is not recommended.

If your power cord becomes damaged or lost, please ensure you order a replacement from 3D Systems for a power cord that is adequately rated for the machine. Do not replace the power cord with a cord that is not rated for the printer. 3D Systems will identify any parts that are required to be examined or supplied only by 3D Systems or its partners.

Part 2

Heat Dissipation

The NextDent 5100 Printer is not expected give off significant heat under normal operating conditions.

Connection to AC Power

  • In the United States, connection to a standard 10-amp wall outlet is required. The system connects to a 120VAC power outlet through a standard 120VAC power cord.
  • In Europe, a standard 10-amp wall outlet is also required. The system connects to a 230VAC power outlet through a standard 230VAC power cord. Country destination kits are available with the proper wall-power connections.

Temperature

The temperature in the room or location where the NextDent system resides should remain stable to allow optimal system operation and optimal part quality.

NextDent resins should be kept between 5°C-30°C (41°F-86°F). However, successful printing has only been tested at a minimum of 18°C (64.4°F) and a maximum of 28°C (82.4°F). If your room is kept beyond either extreme, you may see a degradation in print quality.

Humidity

The optimal humidity in the NextDent 5100 Printer build chamber and lab will depend to a certain degree on the NextDent material selection. Regardless, the humidity should always be non-condensing and should not vary outside the range of 20 to 80% RH. Review your NextDent material information (SDS, Instructions for Use, and product labeling) for specific information on recommended humidity levels.

Altitude

The NextDent system is capable of operating correctly up to an altitude of 2,400 m above mean sea level.

Ventilation

While outside venting is not always required, there are some materials for which outside venting is necessary. Your HVAC system should perform at least six air exchanges per hour in the room where the printer is located. You may wish to have a fume hood installed for your part-cleaning area. Ensure that your facility complies with all local and regional regulations regarding ventilation of vapors, dust, and other by-products of printing, cleaning and secondary processing.  Always refer to and follow the information on the SDS for your specific material.

Part 3

Overall Sound Pressure Level (OASPL)

The sound of the NextDent system will not exceed 80 db.

Air Cleanness

The room housing the NextDent system should be prepared for odors related to a small material spill. The means that windows should be able to be opened and/or other measures can be put in place to vent the room in the case of a spill. Reasonable care should be taken to minimize dust and smoke which could contaminate the NextDent material and cause deterioration of optical surfaces. Avoid temperature fluctuation. Since dust, smoke and temperature fluctuations can affect the performance of the machine and the quality of the parts, an area with filtered air flow is recommended. Avoid proximity to machine shop areas, or where milling, grinding, or sanding is performed.

Lighting

Standard fluorescent lamps with clear plastic diffusers are recommended to minimize ultraviolet exposure, which could negatively affect the NextDent material. Sunlight, quartz-halogen lamps, and high-intensity incandescent lamps are not suitable; and UV-intensive lighting or ultraviolet exposure through windows should be avoided. UV filters are available for windows and exposed fluorescent lamps. Any exposure of the resin to any of the light sources described in this section is likely to cure the resin, thereby wasting it and forcing a difficult cleanup.

Door or Other Method of Preventing Access to Room

The site should be able to be isolated from other employees or personnel in the event of a material spill or major machine malfunction. A separate room or area that can be closed to others is necessary. The system is safe and does not present hazards to properly trained personnel operating the system in accordance with our specifications. However, the system should be installed in an area that can be cleared of untrained personnel during emergency situations.

Network Access

The NextDent system controller computer includes a Class A Ethernet interface, which can be connected to a 10/100/1000 MBit/s Ethernet network to offer network access to the NextDent system. To remotely operate the NextDent 5100 Printer or to remotely run service engineer diagnostics, a VPN network access is required.

Telephone Service

Dedicated telephone lines are not required for normal operation of an NextDent system. You may wish to install a dedicated telephone line in the NextDent system installation area to facilitate discussions with 3D Systems Customer Service personnel while the machine is in operation, should the need arise.

Site Selection - Post Processing Equipment

Locating the post-processing equipment is similar in many respects to locating the NextDent 5100 Printer. The following abbreviated site specifications are for recommended post-processing equipment.

Space and Location Selection

You may choose to locate the part-washing, drying, and curing stations in the same room as the NextDent 5100 Printer or in a room adjoining the printer

With either option, please consider the following:

  1. The further the distance the build part is being moved from the printer to the post-processing area, the longer the opportunity for the build part to get damaged by dropping, bumping into objects, and other environmental factors.
  2. The further the distance the build part is being moved, also longer is the opportunity for uncured resin to drip onto the floor. If floors are porous, such as carpeting or some tiles, they can absorb the spilled resin and would need to be professionally cleaned or replaced.

Refer to Optimal Site Layout for a suggestion for overall layout. Refer to the Weights and Measures Charts for weights and measurements of the LC-3DPrint Box. Consider the following additional specifications when selecting the location for your post-processing equipment.

NextDent LC-3DPrint Box Measurements

curing-chamber-w_dimensions.jpg

Floor Surfaces

Flooring/table/countertop under the post-processing equipment should be non-porous and suitable for cleaning with solvents. Carpeted floors are not recommended.

Electrical Requirements

NextDent LC-3DPrint Box

Power configuration: 110V/240V – 50/60Hz – 2.6A/1.3A

Electrical power for the LC-3DPrint Box must be on a surge-protected circuit. A UPS, while not required, is recommended in areas with frequent power fluctuations, as surges and spikes can damage electronic components and power loss can damage the unit.

Ultrasonic Cleaner

Power configuration: An example of the power configuration for a consumer-grade ultrasonic cleaner is 120W at 40,000Hz. There are ultrasonic cleaners of many sizes, from around 2.5L (0.66 gal.) to upwards of 757L (200 gal.) Determine which size ultrasonic cleaner is best for your needs.

Electrical power for an ultrasonic cleaner must be on a surge-protected circuit, particularly for a bigger (not desktop) cleaner. A UPS, while not required, is recommended in areas with frequent power fluctuations, as surges and spikes can damage electronic components and power loss can damage the unit.

Connection to AC Power

The LC-3DPrint Box is designed to plug into a standard power outlet in different countries. Smaller ultrasonic cleaners will also plug into standard wall outlets; bigger ones, however, may require a custom power outlet.

Ventilation (Ductwork)

The post-processing equipment may be vented outside if required by your facility; however, ventilation is not required by 3D Systems. Contact your Facilities Manager for your requirements.

CAUTION: Never disconnect a ducting system that is connected to an external extraction system.

Third Party Supplies and Equipment

3D Systems™ provides this partial list of equipment and supplies/accessories that are useful for handling, processing or finishing NextDent parts.

Inspect Exterior of Printer

Visually inspect the exterior of the printer for any damage incurred during shipping. Notify your reseller immediately if any damage is evident at this point. DO NOT proceed with the installation until you have discussed the damage with your reseller.

System Installation

Installation of your system encompasses four separate steps:

  1. Purchase and arrival of third-party equipment or supplies you may have ordered.
  2. Delivery of your NextDent system shipment.
  3. Uncrating and installation of your NextDent system components.

System Uncrating

The uncrating and installation of the NextDent 5100 will be performed by the printer operator. The weight of the printer requires a minimum of two people to lift it safely.

Lift.png

Scheduling Time for Your Installation

The installation of the system should only take an hour or less.

Preparing for System Installation

In preparing your facility for NextDent system placement, you must consider four main factors:

  • Make sure that you have the necessary doorway and passageway clearance to move either the crated or uncrated components to their final destinations, including space for the people who are carrying the unit.
  • Make sure that you have an adequate pallet jack, hand truck, or another person to help move the system and its accessories.
  • If you use equipment to lift the printer, verify that it is rated for the load of the system components.
  • Do not prepare a desk/table/countertop for the printer unless it is rated to hold a load of at least 34.5 kg (76 lbs).

Minimum Passageway and Door Openings

Most standard doorways and halls provide adequate access for moving the system. If the NextDent 5100 Printer is lifted on its narrow side, each passageway and doorway must be wide enough to move and turn a printer measuring 42.6 x 48.9 x 97.2 cm (16.8 x 19.3 x 38.3 in), in addition to accommodating the people or equipment used to move the printer.

Determine the pathway from where the crated components are stored to where your NextDent system will be installed. Walk the path from the storage location to the final destination of the system, and measure any critical doorways or passageways to ensure that the equipment can be moved through the area.

If a passageway or doorway is too small for the crated NextDent system, it may be necessary to remove the NextDent system from its crate before moving the unit. A standard door that is 2-2.4m (6.5-8 ft) tall and 0.61-1.1m (2-3.5 ft) wide should accommodate the system and its accessories. 

Considerations for Material

You are responsible for ensuring that the facility where your NextDent system and NextDent materials are housed is properly configured for safe operation of the NextDent system and of the materials used in that system. Personnel who operate the equipment or use the materials must comply with all relevant safety codes and applicable regulatory requirements and laws, particularly those that relate to usage of hazardous chemicals, radiation, and disposal of regulated material. The NextDent 5100 Printer complies with CE requirements.

NOTE: You are responsible for determining whether additional supplies and equipment are necessary according to local, state, federal or other regulatory laws that govern your location.

NextDent Material Usage

NextDent materials in the liquid state require use of approved surgical-type 100% nitrile gloves and other equipment to protect the user from direct contact with uncured print material. Material is fully cured only after adequate exposure in the LC-3DPrint Box. Only after being fully cured do the parts no longer require protective gloves to handle. The LC-3DPrint Box has been designed especially for NextDent™ materials, as their end-use parts must qualify as certified medical devices. Use of another UV oven nullifies this certification.

Material Disposal

Because NextDent materials are regulated, they are subject to special disposal requirements by your local, federal, or other regulatory agencies. Follow applicable disposal guidelines. Contact a local waste management company for recommendations on disposal requirements that affect your facility.

If your area requires regulated waste disposal, consult with and retain a waste-management company to periodically pick up regulated waste. Your local waste management company may recommend that you set up a drum, or other approved container, to dispose of liquid material, partially cured printed parts (also called "green" parts), and of any materials (such as paper towels or gloves) that may have come into contact with the uncured liquid material.

After final part curing in the LC-3DPrint Box, fully cured NextDent parts may be disposed of in regular trash receptacles.

NOTE: Inspect printed parts after curing in the LC-3DPrint Box to ensure they are fully solidified. Part-surface tackiness and visible or discernible areas of liquid material indicate the part is not fully cured.

Please see Pedestal unpacking instructions in the Quick-Start Guide on the page Guides Inside the Box.

Place Printer on Pedestal

Please see instructions for placing printer on the pedestal in the Quick-Start Guide on the page Guides Inside the Box.

Level the Printer on Pedestal

Please see instructions for leveling the Printer on the Pedestal in the Quick-Start Guide on the page Guides Inside the Box.

Nesting Printers

If you have multiple NextDent 5100 printers on pedestals, you may use a technique called, "nesting," to set up the printers as closely as possible while still enabling access to all printer doors. This section describes how to nest three printers together. However, you could nest as little as two, and as many as your facility allows.

  1. The printer that will be in the center of your "nest" should have all its leveling feet locked down so that the printer does not move. This is important for future steps so that only the printer you intend to adjust moves.
  2. Ensure that the leveling feet on all the other pedestals are raised up to allow the printers to roll.
raise-up-leveling-feet.jpg
  1. To nest from left to right (facing the printers) position the printer on the left such that the front-right foot can roll over and clear the front-left foot of the printer on the right.
  2. Slowly move the left printer into place, backing the front-right foot as far back as it can go.
  3. From here, move the printer to the left until the casters on the two front feet almost touch. Please see the video clip at the right for a visualization of the proper technique.
nest-printer-left-to-right.gif
  1. To nest the from right to left, you will follow the reverse of Steps 3-5. Facing the printers, position the printer on the right such that the front-left foot can roll under the front-right foot of the printer on the left.
  2. Slowly move the right printer into place, pushing the front-left foot as far forward as it can go.
  3. From here, move the printer to the right until the casters on the two front feet almost touch. Please see the video clip at the right for a visualization of the proper technique. See the clip below for a closer look and a different angle.

nest-printers-overhead.gif

nest-printer-right-to-left.gif
  1. Ensure that all printer doors can open freely.
  2. Level all printers according to the section Level the Printer on Pedestal.
  3. To un-nest the printers, simply raise all leveling feet and slide the printers apart. Re-level all printers by themselves before printing on any of them.
 

 

Install Carbon Filter

Unscrew the carbon-filter bracket from the printer. Remove carbon filter from its packaging and install it in the printer, as seen in the section Change Carbon Filter.

install-carbon-filter-1.jpg→install-carbon-filter.jpg

Turn Printer On

TIP: It may be useful to bundle the power cable and Ethernet cable together with cable ties, and secure them in place, to prevent a tripping hazard.

NOTE: If the printer does not power on, test the power outlet where the printer is plugged in with something you know works, such as a phone charger. Ensure the power cable is completely inserted in both the power inlet and wall outlet. Ensure that any power strip or UPS the printer is plugged into is turned on. If you have tried all these options, and the printer will not turn on, contact 3D Systems Service.

ELECTRICAL SHOCK HAZARD: Be sure that the power switch is in the "0," or "off," position before plugging in the printer.

ELECTRICAL SHOCK HAZARD: Use the power cord that has been supplied with the printer. Using a different power cord could cause electrical malfunction and damage to the equipment.

Turn the Printer On

The power switch and power inlet for the NextDent 5100 is on the back-left side of the printer.

 

  1. Plug the power adapter into the power inlet on the printer. Plug the other end to a wall outlet.

  2. Flip the power switch to the "I" position to turn the printer on.

printer-back-open-(2).jpg

 

Connect the Printer to the Internet

Plug your Ethernet cable into the Ethernet inlet on the back-right of the printer, as shown.

NOTE: Be sure to use the Ethernet cable that came packed in with the printer, as it has been tested to work with the printer. Alternatively, an 802.11n WiFi bridge >300Mbps may be connected to Ethernet port.

NOTE: An offline setup for your printer is available upon request. Contact your reseller for more information.

 

  plug-in-ethernet.jpg

Ensure the Catch Tray is Installed

The catch tray will come installed in the printer. If it is not installed, contact your reseller immediately. If this is your first time printing, remove the catch tray from the printer and ensure that the protective film has been removed from both the bottom and top of the glass plate. The films should have been removed before shipping to you; but you must perform this check to ensure successful printing.

After you've ensured that there is no film on the top or bottom of the glass, you must reinstall the catch tray, as it must be present prior to printing. This is because:

  1. It shields the lower print chamber from resin. If resin gets on the components of the lower print chamber, it can cause irreversible damage to the print engine.
  2. The printer is expecting to project UV radiation through the catch tray's glass. If the glass is not there, you risk over-curing of printed parts.
  3. There is a sensor on the catch-tray rail that can tell if the catch tray is fully seated. If the sensor sees no catch tray, the machine will not allow you to print. Ensure you push the catch tray all the way back to satisfy the sensor.

Please see the section Clean/Replace the Catch Tray for installation instructions.

3D Sprint Part Orientation Guide

For each dental indication that can be printed on the NextDent 5100, part orientation in the part-preparation software is key. This section provides a quick reference for the best ways to orient parts in 3D Sprint for any print material available for the NextDent 5100. This will help ensure build success and maximum usage of the printable area.

CAUTION: Do not attempt to build any other dental indication with a resin other than what that resin is specifically prescribed for. For example, do not use Denture 3D+ to build crowns and bridges. Doing so will result in a failed build and the part that prints will not have any medical certification.

Accuracy Wizard

For each NextDent material, the Standard print mode in 3D Sprint is designed to give you accurate prints right out of the box. Please use the Standard print mode first and foremost to achieve part accuracy. However, if after measuring your parts you find that you have issues achieving accuracy, you may use the Accuracy Wizard in 3D Sprint to troubleshoot such issues.

Each NextDent 5100 printer will vary slightly in accuracy. If you have multiple printers, you will need to set the accuracy for each one separately. To do this, click the Printer icon in the upper left, select each printer one-by-one, and run the steps in this section for each. Additionally, you will need to run the wizard for each Material/Build Style combination you use.

NOTE: Best Practices for using calipers on printed parts is demonstrated here (advance video to 2:38).

 

  1. Click the Load Reference button to load the accuracy models that will be printed.

  1. Open 3D Sprint again and click the Scale & Offset Wizard button to open it. This time, instead of saving a reference build file, you will
    1. Check the box next to The reference parts have been printed.
    2. Click the Next button.
accy-wiz-click-next-1.jpg
  1. Measure the parts printed in Step 6 with calipers or a micrometer in the X and Y directions (Refer to this video, at timestamp 2:38, for proper caliper usage). You will measure the parts four times each in X and Y and input your measurements in the fields in the wizard that correspond to the part you are measuring. You will notice that every time you enter a value, the number in the "Average" column updates to show you the average of your measurements.
  2. Repeat this process for each of the models and click Next when you are finished.

accy-wiz-enter-values.jpg

  1. You will then see the results screen, which will show you how much the printer will now offset builds with this build style. It also shows you the scaling corrections as a percent. Click the Apply button to add this scaling to your new build style (see Step 12).
scale-factors.jpg
  1. You will now be able to select this style from the Build Style menu going forward, allowing you to build with these scale factors at any time.
  2. Remember that the Build Style is tied to the print material you are using. If you use a different print material on another print job, you will need to run this wizard again for that material. The software will automatically create/name the new build style; but you can click the Rename button to rename it.
new-build-style.jpg
  1. When you select this build style in the future, you can verify that it is the style with scale factors applied by looking at the Scaling Factor fields in the Build Style window.
  2. Click File > Save to save your work.
scale-factors-applied.jpg
  1. At any time, you can verify that your accuracy values are still valid by running the verification .f4x file again. Go to Reference Builds > Load Reference Build File. This will automatically place the reference build parts onto the platform with proper supports and orientation.
  2. Click the Add to Queue button to send the .f4x file to the printer.
  3. Run the printing process, as outlined in the section Start Printing. This will print the four parts from Step 15. The dimensions and x/y axes will be printed on the part. Post-process the parts as in the section Post Processing.
  4. Use your calipers or micrometer to measure the parts. If they are not accurate, run Steps 8-10 once more.

  1. The touchscreen is a 4.3” LCD PCAP Capacitive Touch Screen, meaning that it registers an input whenever something holding an electric charge (like fingers) touches it. Touch input has been tested to work with lab-quality, powder-free gloves; however, you should ensure that you do not touch the screen if you have recently handled uncured resin or partially cured printed parts. This is to keep the complete functionality of the screen intact and to not contaminate it.
  2. If resin does get on the screen, clean immediately with >90% alcohol solvent and a nonabrasive cloth.
  3. To wipe fingerprints off the touch screen, use a microfiber cloth.
  4. Do not attempt to remove the touch screen or its casing from the printer.
  5. If the touch screen becomes damaged to the point of not functioning properly, cease printing and contact 3D Systems' Service.

The GUI has three tabs with different functionality:

  1. Status
  2. Queue
  3. Material
  4. Settings

Status Tab

When you have print jobs in your 3D Sprint print queue and there is a material type loaded in the printer's memory, the status screen will look like this: 

GUI-status-screen.jpg
A Status Tab - Tap this tab at any time to return to the "Status" screen.
B Build File Name - The name of the build file sent over from 3D Sprint.
C Print Preview - Shows the 3D model currently being printed
D Current Resin - This is the resin that is currently loaded on the printer.
E Status - The text shows the current state the printer is in
F Progress Bar - Shows the percent complete of the current print job
G Time Estimated - Time the printer should take to build the current job. This changes to Time Remaining when the job is being printed.
H Start Job Button - Tap this button to start the print setup process

First Time Turning Printer On

When you first power on the printer, it will not have any pending jobs or print material loaded. So the status screen will appear like the image at the right. At this point, you should queue print jobs in 3D Sprint and add print material either during the print process or from the Material tab. status-tab-first-time.jpg

 

Queue Tab

The Queue Tab allows you to view the print queue, which shows the current print job and all pending print jobs. It also allows you to move and delete queue items. The default queue screen will simply show a list of jobs. Hold down on a job to bring up the queue-controls seen below.

Queue_Pending-manipulation.jpg
A Back - Tap this button to go back to the default queue screen.
B Move Up - Tap this button to move the job one space up in the queue.
C Move Down - Tap this button to move the job one space down in the queue.
D Move to Top - Tap this button to move the job to the top of the queue.
E Move to Bottom - Tap this button to move the job to the bottom of the queue.
F Delete - Tap this button to delete the job from the queue.
G Selected Job - The job highlighted in blue is the job that is currently selected for moving/deleting.

 

Material Tab

The Material Tab contains information on the material that is currently loaded in the system for printing, and also allows you to change the material you wish to print with. However, you do not have to use this screen to change materials, as the printing process gives you the opportunity to do so. The printer will keep track of how much material is left in each bottle of material that has been scanned to the machine. It will also keep track of the expiration dates of your materials.

materials-tab---home-v2.jpg
A Material Tab - Tap this tab to access the menu and its options 
B Material Name - The name of the material that is currently set for printing appears here. While the printer will keep track of the status of multiple bottles, the printer may only be set up to print with one bottle at a time. See the section Add/Change Material and Scan Bottle for more information.
C Material Part Example - This display demonstrates what a part printed with this material could look like.
D Lot Number - Also called the "batch number," this refers to the batch of material that your bottle was sourced from.
E Exp. Date - The expiration date of the material. After this date, the material is no longer certified to print parts used as medical devices.
F Change Material - Please see the section Add/Change Material and Scan Bottle.

  1. On the printer, ensure that you see the "Update Complete!" screen at the right. If you do not see this, navigate to the Settings tab to check if the firmware version has been updated. If it has not, perform the upgrade again. If the issue persists, contact your reseller.

Prepare and Install the Resin Tray

Resin Tray Guidelines

The membrane contained within each resin tray is the most fragile component of the NextDent 5100 Printer. It must be handled with care. Follow all resin-tray guidelines and procedures to avoid membrane damage and failure.

HARMFUL IRRITANT WARNING: Wear protective clothing, disposable nitrile gloves, and goggles while handling the resin tray.

CAUTION: If a leak/spill occurs, do not run the machine. UV curing will harden the resin on unwanted surfaces and will make the resin very hard to remove. A nonabrasive cloth and >90% alcohol solvent will help clean up any spilled uncured resin.

CAUTION: Failure to clean the resin tray of partially cured resin will lead to membrane failure and failed prints.

 

  1. Expected lifetime of the resin tray is around 900 builds.
  2. Do not apply pressure to the membrane. Deformations form easily and permanently, and may lead to membrane failure and degradation of print quality. Never touch the membrane with sharp objects.
  3. Do not touch the membrane with bare skin. Skin oils may cause print-quality degradation.
  4. Always verify that all printed parts and supports have been accounted for after a build. Be sure to inspect the resin tray for partially cured material. Cured material (also called green material) that is clear, or tiny bits of cured material may not be visible to the naked eye. If you suspect that partially cured material might be present in the tray, you must clean the tray before building again.
  5. Do not allow the resin tray to run out of print material during a print, as this will result in build failure. Do not add resin during part building. Resin in the bottle will be a different temperature than resin in the tray during building. This may cause undesirable build quality and/or build failure.
  6. With thorough cleaning of the resin tray in between builds, it is possible to use different resins in the same resin tray (not at the same time). Please see the section Resin Tray Resin Cross-Usage for information on which resins may share a single resin tray. Do not mix two or more types of resin in the resin tray. Doing so will cause both materials to become ineffective.
  7. Avoid transporting a resin tray that is filled with resin so as to avoid spills. Always carry resin tray with both hands to help ensure that it does not drop on the floor. Any damage to the resin tray would mean that the resin tray needs to be replaced.
  8. Do not move the printer while there is a resin tray inside that is filled with resin. Even moving the printer a few inches with resin inside can cause a resin spill.
  9. Uncovered resin trays should not be left outside the NextDent 5100 Printer when containing any amount of print material. Material will cure when exposed to ambient light. Cured material is extremely difficult to remove from the resin-tray membrane without causing damage. If you store a resin tray containing material outside the printer, use the resin-tray garage and store the tray in a cool, dark place.
  10. Resin overflow from the resin tray will be channeled into the catch tray. Discard the resin in the catch tray according to all government regulations.
  11. Never pour resin from the resin tray back into its bottle, nor into any container of common material. Failure to follow this guideline risks contamination, and/or improper mixture, of print material in the bottle.
  12. Always ensure the resin tray is clean of uncured liquid resin and partially cured bits before each print.
  13. Always ensure that the resin tray is not damaged in any way, particularly on the membrane. Tray damage could cause build failure and/or resin leakage. Resin-tray damage can be: membrane puncture, dent, scratch or discoloration.

Install Resin Tray

NOTE: A print platform should not be installed during this procedure.

CAUTION: If tension system is damaged in some way, do not attempt to force any components to engage/disengage. Doing so could further damage the tension system, as well as other parts of the printer. Contact 3D Systems Service immediately.

Wear 100% nitrile gloves whenever reaching inside the print chamber.

 

 

  1. Open the front door of the printer.
 
  1. Push in the tension-arm release lever on the front of the tension arm and lift up the tension arm. The arm will stay in place in the up position.

lift-tension-arm.gif

  1. Carefully lower the resin tray into place, concave side up, as seen at the right. It should fit snugly in the holder on the chassis.

bottom-of-print-tray.jpg

install-resin-tray.gif
  1. Apply tension to the membrane by flipping down the manual tension arm until the release lever locks it in place.

CAUTION: Major build defects and/or membrane failure will result if a print is attempted on an untensioned membrane.

print-tray-orientation-v4.jpg

Add/Change Material and Scan Bottle

Once a material type has been loaded, this is the material that the printer is expecting for the next print job. But you may wish to change the type of resin you are using. Most of the time, you will be changing the material as part of the printing process. However, you can also tap the Change Material button at the bottom of the Material tab home screen to change the material type to be used on your next print. You can also use this screen to add print material for the first time. If you have not yet activated your printer, you must do so in order to get through the following steps. Please see the section Printer Activation for more information.

NOTE: The screens in this section will be slightly different depending on whether you are changing the material type or adding material for the first time.

 

  1. On the Material tab, tap the Change Material button.
change-add-resin.png
  1. The scanner below the touch screen will be activated and you will see a screen like the one at the right. Hold your material bottle's QR code in the path of the scanner such that the center dot is in the middle of the QR code (see image below).

CAUTION: The printer keeps track of how much resin is used from your bottle. Ensure you are pouring from the same bottle you scanned. Using one bottle to scan and another to pour from will result in the printer thinking your bottle is empty after a certain amount of pours.

scan-bottle-qr-user-guide.jpg

looking-for-new-resin-bottle.png
  1. If the scan is successful, you will see the Bottle Found screen, like the one at the right. If the scan is not successful, this could be for a number of reasons, which are outlined in the section Printer Error Messages.
bottle-found-v3.jpg
  1. Remove the print platform and resin tray, cleaning them both, as per the sections Clean Print Platform and Clean Resin Tray.
scrape-supports-(2).jpg
  1. After removing the resin tray, label it on the outside with an identifying number, letter, or word(s) to let you know which material was in it before.
label-print-tray.png
  1. If the catch-tray glass has a large amount of spilled resin on it, you must dispose of it according to all government regulations and replace it with a new catch tray. If it has no resin, or just a few resin spots on it, clean the glass with >90% alcohol solvent on a nonabrasive cloth, according to the section Clean/Replace the Catch Tray.
remove-catch-tray-v2.jpg
  1. Reinstall the print platform.
print-plat-in-machine-cu.jpg
  1. Install a new resin tray or reinstall the cleaned old one, as per the section Install Resin Tray.
  2. If this is a new resin tray, label this tray with the same naming convention used in Step 5.
label-print-tray-2.png
  1. On the Material tab, your new material will be loaded. Fill the tray with the new material and check the boxes on the screen. Tap Confirm.
gui-add-mat-cklist.jpg

You are now ready to perform the print process with a new material. 

Resin Tray Material Cross-Usage

You may clean the resin tray with >90% alcohol solvent between builds, enabling you to use different print materials in the same resin tray (not at the same time). However, ensure that the cleaning is very thorough when switching between materials, as residual material in the tray will mix with the new material and create an improper mixture.

Mixing, Stirring, and Curing Chart

Before pouring any NextDent print material in the resin tray, you must mix the material bottle according to the chart below. Before printing again with those materials, you must stir the material in the resin tray using the Resin Mixer. Stirring the material in the resin tray serves two purposes: 1. Ensuring a good material mixture; and, 2. Ensuring there is not debris in the resin tray, such as partially cured particulates.

Resin Stirring and Curing Chart

CAUTION: Failure to sufficiently mix print materials according to this chart may result in color deviation and/or print failure.

 

The chart below serves as a quick reference for material-bottle mixing time on the NextDent LC-3DMixer, bottle hand-mixing time, material stirring time when material is in the resin tray, and part-curing time in the LC-3DPrint Box. For hand-mixing, shake the bottle vigorously in an up and down motion.

For part-washing times, these are identical for all NextDent materials. The first part bath should be three minutes in an ultrasonic cleaner with >90% alcohol solvent. The solvent may have been used to clean other parts for this first bath. The second part bath should be two minutes in an ultrasonic cleaner with clean >90% alcohol solvent. The solvent may NOT have been used to clean other parts.

As for part-drying times, these can vary depending on your drying method. Please see the section Part Drying for more information.

*Pre-shaking by hand

For best printing results, most NextDent print materials require that you pre-shake the bottle by hand before placing it on the LC-3DMixer for the specified time. This is to ensure that sediment thoroughly mixes with the rest of the material.

**Considerations for material that has been sitting, unused, for over 1 month

If you have a material bottle like this, simply treat it like a new bottle and mix it for the time specified in the "Brand-new bottle" column in the above chart.

 

NOTE: Ensure that you place the build in your UV curing oven in the same orientation it was printed in, as if the bottom of the oven is the print platform.

Fill Resin Tray With Material

HARMFUL IRRITANT WARNING: Always handle the resin tray with care, even if you believe there is no material in it. wearing contact lenses when handing a resin tray filled with material is not recommended. Wear 100% nitrile gloves when handling the resin tray, even if you believe there is no material in it. Be careful not to pour material outside the resin tray, or to allow material to splash outside the resin tray. Liquid material has the potential to damage electrical equipment, particularly in the lower part of the printer.

TIP: You may choose to hold the material bottle with two hands, just in case it slips out of one hand, so that you do not drop the material bottle.

Mixing Old and New Materials

NextDent materials are assigned a "lot number" when they are manufactured. This number can be found on your bottle of material.

Biocompatible Materials

For biocompatible materials, those that are CE certified as a medical device, you can NOT mix materials that come from two different lot numbers, even if they are the same material type. Doing so will compromise the ability of 3D Systems to reconcile any issues that might arise with these materials. Biocompatible materials currently include: Surgical Guide (SG), C&B MFH, Ortho IBT, Ortho Rigid, Tray, Denture 3D+, and Try-In.

Non-biocompatible Materials

For non-biocompatible materials, those that are not CE certified as a medical device, it is permissible to mix materials from different lot numbers. These materials are not registered and do not have the same restriction. Non-biocompatible materials include: Model 2.0, Cast, and Gingiva Mask.

Fill the Resin Tray

Before filling the resin tray, you should have completed the steps in the section Add/Change Material and Scan Bottle. If you have not done so, do so now.

CAUTION: Failure to properly switch materials will result in reduced reactivity of the new material, even when only very small amounts of different material(s) are mixed in. This will result in build failure and wasted material.

 

  1. Before pouring the material into the resin tray, be sure you do the following:
    1. Mix the material on the NextDent LC-3DMixer for time specified for your material in the Material Stirring and Curing Chart.

      CAUTION: Failure to sufficiently mix materials before each build may result in color deviation and/or print failure.

    2. If you are using the same material bottle as in your previous build, be sure that the print platform and resin tray are completely clean of debris (such as dust), and/or partially cured material residue.

      CAUTION: Failure to clean the resin tray and print platform of debris may affect the material's reactivity and the printed part's ability to adhere to the print platform.

    3. If you are using a new bottle of the same material, but it has a different lot number than your last bottle, you must either empty the resin tray of the previous material or use a different resin tray for the new bottle. Please see the section above about mixing old and new material.
lc-3d-mixer-hero.jpg
  1. Before filling the resin tray with material, take note of the markings printed on the front and back.
    1. The MIN mark indicates that the 5mm (0.2 in) pool in the bottom of the tray is full. Do not print if the resin level is below this line.
    2. Each numbered mark indicates 100mL (3.4 fl. oz.) more of resin on top of the 5mm pool, on up to 400mL (13.5 fl. oz.).
    3. The MAX mark indicates a resin level of 430mL (14.5 fl. oz.). See caution statement below.

Keep in mind that the largest possible build on the printer consumes around 200 mL (6.8 fl. oz.) of material.

CAUTION: Do not fill the resin tray beyond 430 mL (14.5 fl. oz.). Doing so risks spilling material and/or getting material on elevator arms during printing.

resin-fill-lines-side.jpg
  1. Slowly pour material until desired height is reached. Hold the bottle low over the tray while pouring to avoid splashing.

TIP: Remember to keep your resin bottle, even after you've emptied it, so that you still have its QR code. If you pour more than one print job's worth of material into the resin tray, you must continue to use the bottle you poured from to scan its QR code before printing. Scan this bottle until your material has printed off. This will allow the printer to properly track how many pours your bottle has been through.

pour-resin.jpg
  1. Close printer lid as soon as possible after pouring, so as to avoid any unnecessary exposure of the material to ambient UV light.
 

 

Mixing Material in the Resin Tray

Resin that is left in the resin tray between builds needs to be stirred periodically. In this case, you would use the resin mixer to stir the resin, as seen below. Refer to the Resin Stirring and Curing Chart for information on stirring materials.

CAUTION: Failure to sufficiently mix resins before each build may result in color deviation and/or print failure.

CAUTION: Ensure that the comb is clean before each use. To clean the comb, wipe it with a nonabrasive cloth and the recommended solvent.

 

  1. Run the comb through the resin, with the sharp end (A) facing down. Grip the comb on the indented gripper (B). Please see the images below for the proper stirring technique.

CAUTION: Do not scrape the comb's blade from side to side like a knife. Rather, move it back and forth like an ice scraper.

proper-stir-resin.png

print-tray-comb-10162017.jpg
  1. Holding the comb slanted, run it back and forth through the resin, careful not to put too much pressure on the resin-tray film. Do this for the time prescribed in the Resin Stirring and Curing Chart, or until all resin that has stuck on the resin-tray film has been scraped off. You are looking for stuck-on resin spots like that which is circled below:

scrape-resin-off-bottom.jpg

stir-resin.gif
  1. After stirring, allow the comb to drip resin back into the resin tray and then wipe excess resin off the comb with a nonabrasive cloth.
clean-resin-comb.png

CAUTION: Putting too much pressure on the resin-tray film can dent or puncture the film, rendering the tray unusable. The film cannot be replaced by itself; if the film is damaged, the whole resin tray must be replaced.

CAUTION: Puncturing the resin tray will force a full tray's worth of print material into the catch tray. Use extra caution when handling a full catch tray.

CAUTION: If the resin tray gets punctured, discard it in the same way you would other materials that have been in contact with liquid resin.

CAUTION: Take care not to slosh resin out of the resin tray while stirring. If this happens, you will have to clean the parts of the printer that the resin got on.

  1. Repeat the stirring process as indicated by the Resin Stirring and Curing Chart.

CAUTION: Be sure to clean the resin mixer with >90% alcohol solvent between uses. Failure to do so risks mixing unstirred resin or different resin in with material currently in the resin tray.

 

Prepare and Install the Print Platform

Print Platform Guidelines

Print platforms should be treated with care in order to preserve their shape and coating. Avoid dropping print platforms. Print platforms should be thoroughly cleaned and inspected after every use to ensure print adhesion, to ensure that two different resins do not mix, and to avoid resin-tray membrane damage.

  1. Remove and post-process the printed part and the print platform either together or separately, according to your purposes.
  2. Once the printed part is separated from the platform, follow the instructions in the section Clean Print Platform before reusing the platform.
  3. Inspect the following areas for cured resin. If cured resin is present, remove using the included Platform Scraper.
    1. Elevator guides
    2. Print surface - underside of print platform
    3. Print surface holes
  4. Verify flatness of the print platform. Ensure the platform has not become concave, convex, or scratched to the point of making a groove. To check this, follow the procedure in the section Check Print-Platform Level. If the platform is damaged, as discussed or otherwise, dispose of the platform. The user is responsible for determining the integrity of the print platform before using it to print.
  5. Always handle the print platform with two hands, so as to prevent dropping it on the ground. A drop could cause damage to the platform, as well as get debris on it, which could contaminate the resin in the resin tray.
  6. Contaminants such as dust, oils from the skin, or cured print material can cause poor print adhesion and/or resin contamination. Even if it appears there is no contamination, clear resins, or small bits of cured material may not be easily spotted by the naked eye. Because of all these factors, clean the platform as well as possible in between builds and always wear 100% nitrile gloves when handling the print platform.
  7. Never attempt to move the elevator arms by hand. The elevator should only be operated via the printer's GUI.

Install Print Platform

Always wear 100% nitrile gloves when handling the print Platform.

CAUTION: The printer will operate without a print platform installed. Ensure you install it before every print.

CAUTION: Do not leave the printer lid open for an extended time. Leaving the lid open will allow light to cure the material inside and will also allow dust/contaminates in.

 

  1. Open the printer lid by pulling the handle on the front. It will stay open by itself once you lift it.
printer-lid-open-2.jpg
  1. Verify the platform has been properly cleaned and is not visibly warped. A properly cleaned print platform will not have any residual print material or contaminants of any kind present. Special attention should be paid to the print surface (1), and elevator guides (2).
  2. Also make sure the elevator is at its upper limit, or offload, position before installing the platform.
print-surface-and-elevator-guides.jpg
  1. Install the print platform onto the elevator arms, convex side down, as seen at the right. The triangular groove on each print-platform elevator guide lines up with the cone-shaped pin on each elevator arm. Ensure the print platform is fully seated and level. Magnets will secure the platform in position. If you feel there is an issue with how the print platform is sitting on the elevator arms, do not build on the printer. Contact 3D Systems customer service.

Start Printing

Prepare Build File in 3D Sprint

Before printing can begin, you must prepare a 3D model in 3D Sprint, slice the file, and export the sliced file to the printer. When in the 3D Sprint Software, you can click the help icon new.png icon, or press F1, for full software instructions. If you do not wish the print job over your network, please follow the steps in the section Submit Build File via USB.

Printing for the First Time

If you are building for the first time on the printer, the Quick-Start Guide will walk you through running a verification build to ensure the printer is functioning normally. It is highly recommended to print this part before attempting any other builds on the printer. This build is not meant to test the printed parts for accuracy. To test accuracy, please follow the instructions in the section Accuracy Wizard.

CAUTION: Do not run this test print without resin in the resin tray. It is necessary to print the part and observe part quality to ensure that the test print was a success.

Print Process

  1. Once you have sent a build file to the printer from 3D Sprint, the printer's Status screen will look like the screen at the right. Tap the Start Job button.

NOTE: If the pending print job requires a resin that is different than the one loaded on the printer, you will be prompted to take steps to change the loaded print material, as seen in the section Change Material Before Printing.

start-job-button.jpg
  1. The QR-code scanner below the touch screen will be activated and the printer will ask you to scan a bottle of the print material sent over in the build file from 3D Sprint. You will see a screen similar to the one at the right. Ensure you are scanning the correct material bottle and hold the bottle's QR code in the path of the scanner such that the center dot is in the middle of the QR code.

scan-bottle-qr-user-guide.jpg

please-scan-bottle.jpg
  1. If the scan is successful, you will see a screen similar to the one at the right. If the scan is not successful, this could be due to a few different reasons, which are outlined in the section Printer Error Messages.
bottle-found.jpg
  1. The printer will remind you to perform three tasks before proceeding with the print job. Tap each check box as you perform each task.
    1. Empty and clean print platform, as in the section Clean Print Platform.
    2. Mix the material, as in the section Mixing, Stirring, and Curing Chart. This refers both to stirring the material that is currently present in the resin tray and mixing the material that is in the bottle.
    3. Fill the resin tray from the material bottle you just scanned, as in the section Fill Resin Tray With Material.
printing-checklist.jpg
  1. Tap Start Job button.
check-all-boxes.jpg
  1. You will see a screen like the one at the right, with the progress bar showing the "percent complete" of the print job. You will also see a print preview of what is currently printing. You may abort the print job at any time by tapping the Abort button. Please see the section Abort a Print Job for more information.

  1. Once the job has completed, you will see a screen like the one at the right. Please proceed to the section Post Processing.
print-complete.jpg

Submit Build File via USB

If you do not want to submit your build file over a network, you may save the build file to a USB drive and upload it to the printer. This section assumes you have prepared the build file in 3D Sprint and transferred the file to a USB device.

NOTE: The printer only accepts USB drives formatted in FAT32 or NTFS. If you experience issues with the printer reading your USB device, you can troubleshoot by turning the power switch on the back of the printer off, and then on again. If you continue to experience issues, contact your reseller.

 

  1. At any time, even during printing, you may insert a USB device with .f4x or .pxl files on it. The printer will automatically look for these files and show the screen at the right if it finds them. Tap Dismiss if you do not wish to transfer USB files at this time. Tap Select Jobs to bring up a list of the build files on the USB device.

NOTE: If the printer finds a firmware-update file on your USB device, it will prompt you to update the firmware with that file before it shows any of the print jobs on the device. Tap "Cancel" and the printer will then show the "print jobs" screen at the right.

NOTE: The PXL format slices the file in 3D Sprint, which makes the job-submission process faster than submitting with the F4X format. However, the file will be optimized for the printer that Sprint was connected to at the time the file was created, while F4X can be used effectively on any of your NextDent 5100 printers. See the section Submit Build File via Network for more information on F4X.

usb-print-jobs-found.jpg
  1. Tap the checkbox next to each print job you wish to add to the printer queue. When you have selected all the files you wish to add to the queue, tap Add to Queue.

NOTE: The printer can store up to 32 queued jobs at a time.

usb-submit-select-files.jpg
  1. You will see a screen like the one at the right to confirm that your jobs have been added to the print queue. Tap Continue to go back to the screen the printer was on before this process.
usb jobs have been submitted.jpg

Submit Build File via Network

One way to submit your build file to the printer is over your network via 3D Sprint. This section summarizes the process. For full 3D Sprint instructions, see the 3D Sprint Help Menu.

  1. In 3D Sprint, click Add to Queue. This will automatically send the build file as a .f4x file.
add-to-queue.jpg
  1. The print job will appear as pending in the queue for up to five minutes before being able to print.

NOTE: The F4X file format will slice the file on the printer itself, as opposed to the PXL file format, which slices the file in 3D Sprint before outputting it. See the section Submit Build File via USB for more information on the PXL format.

preparing-job-in-queue.jpg

 

Change Material Before Printing

If the print job sent over from 3D Sprint uses a different print material than that loaded on the printer, one of two screens will pop up, prompting you to take certain actions:

Pending Job Requires a Different Material - Materials Compatible

different-material-message.jpg

When you see this screen, it means that the material currently loaded on the printer is not the same material that was sent over in the build file AND that the new material and the old material ARE compatible with the same resin tray, according to the section Resin Tray Material Cross-Usage.You must now:

  1. Either replace the resin tray or clean it as seen in the section Clean Resin Tray. Install the new or cleaned resin tray. Once you have done this, tap Continue.
  2. You will see a screen similar to the one below:
    looking-for-resin-bottle.jpg
  3. Scan your material bottle, as in Step 2 of the section Start Printing. Continue with Step 3 of the printing steps in that section.

Pending Job Requires a Different Material - Materials NOT Compatible

resin-print-tray-not-compatible.jpg

When you see this screen, it means that the material currently loaded on the printer is not the same material that was sent over in the build file AND that the new material and the old material are NOT compatible with the same resin tray, according to the section Resin Tray Material Cross-Usage.You must now:

  1. Replace the resin tray. Once you have done this, tap Continue.
  2. You will see a screen similar to the one below:
    looking-for-resin-bottle.jpg
  3. Scan your material bottle, as in Step 2 of the section Start Printing. Continue with Step 3 of the printing steps in that section.

QR Code Override

When you scan a bottle's QR code, there could be an error in reading the code itself. You should contact 3D Systems Customer Service to let them know you have a faulty QR code on your bottle. However, it is possible to continue printing for a limited number of builds by overriding the QR code requirement. This section describes how to access QR code override.

  1. The first time you experience a scanning error, you will see a screen similar to the one at the right. This can happen if the printer determines it cannot read the code, or if the printer has not read the code within 30 seconds of the scanner being activated.
error-in-scanning-qr-code.jpg
  1. The second time you experience a scanning error, you will see a screen like the one at the right. Tap Try Again to scan the bottle again. Tap Select Bottle to go to the QR Code Override screen.
could-not-read-code-select-bottle.jpg
  1. If you tapped Select Bottle in Step 2, you will see the screen at the right. This screen shows a list of the last 20 unique bottles scanned to the printer that have not been marked as "empty." Tap the bottle that matches the resin you are using. If you do not see your resin listed, contact 3D Systems Customer Service.
mqg-override-choose-bottle.jpg
  1. Once you have selected a bottle, you will see a confirmation screen like the one at the right. Tap Select to confirm the bottle. The printer will then pick up with Step 4 from the section Start Printing.
mqg-override-confirm-bottle.jpg
  1. If you have exceeded the amount of overrides the system allows, you will see a screen like the one at the right and will not be allowed to override the QR code requirement anymore. Tap Try Again to scan your bottle again or scan a new bottle. Contact 3D Systems Customer Service for more information.
mqg-override-disabled.jpg

Abort a Print Job

There are two ways that you may abort the print job:

  1. Trip a printer sensor during a print.
  2. Tap the Abort button on the touch screen:
    tap-abort.jpg

Safety Sensor is Tripped

The printer has three safety sensors that, when tripped, will abort the current print job without warning. In any of these cases, you will see the screen at the right and the elevator will move to the offload position.

  1. Lid - Because the resin cures with UV light, exposure of the printed part during printing to any other light besides that of the projector can cause a failed build and can cure the resin in the resin tray. For this reason, if you open the printer lid or lower-chamber door during printing, the print job will be aborted.
  2. Front Door - To avoid operator exposure to optical radiation, the printer will also abort the current job if the front door of the printer is opened during printing.
  3. Catch Tray - In the unlikely event that the catch-tray sensor malfunctions during a build, or if the catch tray becomes loose during a build, the print job will abort to protect the bottom of the print engine.

CAUTION: Take care not to place the printer in a place where it might be run into or shaken, causing any of the above actions to happen accidentally.

 

One of the three sensors might also trip just after you press the Start Job button in Step 5 of the section Start Printing. This will abort the pending job and you will see the screen below:

safety-sensor-trigger-no-job.jpg

job-aborted-safety-trigger.jpg

Tap "Abort" Button

  1. Tapping the Abort button during a print will not immediately abort the print. You will see the popup at the right. Tapping the Abort button on this screen will abort the job. There is no further warning.
abort-current-job-v2.jpg
  1. You will see the screen at the right and the elevator will stop.
aborting-screen-v2.jpg
  1. Once the build is aborted in either case, the printer's Status screen will appear like the one at the right. You can take the following actions:
    1. Tap the Reprint button to restart the build. This will begin the printing process again from Step 1 in the section Start Printing.
    2. Tap the Next Job button to prepare the printer for accepting a new build.
print-aborted.jpg

Change Air Filter

Frequency: Every 3 months, or when prompted by touch screen

The air filter is located on the back of the lower build chamber. A fan inside the printer pulls air in to cool off the printer components. This filter keeps contaminants out of the air being pulled in. If the filter gets resin on it, it must be replaced IMMEDIATELY.

CAUTION: If you need to move the printer to perform this procedure, you must remove the resin tray and place it in its garage before beginning. Also, you will need to lift all leveling feet to move the printer and will need to re-level the printer once this procedure is done.

CAUTION: Failure to change the filter when prompted could lead to a clogged filter, which would block the cooling fan from taking in air. This could cause printer parts to overheat and fail. Similarly, installing a damaged or used air filter may result in overhearing or debris getting in the lower print chamber.

 

  1. Remove the two hand screws securing the bracket to the printer.
replace-air-filter.jpg
  1. Pull the filter out by the cardboard. Discard the filter with your normal trash.
intake-filter-v2.jpg
  1. Inspect the new filter to ensure that it is not damaged in anyway or dirty. Install your new air filter with the convex part facing out.
 
  1. Replace the air-filter bracket and secure with screws taken out in Step 1. Be certain that the screw is tightened adequately and that the bracket fits snugly on the printer frame.
intake-filter-air-flow-04242018.png

Change Carbon Filter

Frequency: Every 6 months, or when prompted by touch screen

The printer software will alert you periodically to replace the carbon filter, located on the back of the upper build chamber. If the filter gets resin on it, it must be replaced IMMEDIATELY.

CAUTION: If you need to move the printer to perform this procedure, you must remove the resin tray and place it in its garage before beginning. Also, you will need to lift all leveling feet to move the printer and will need to re-level the printer once this procedure is done.

CAUTION: Failure to change the filter when prompted could lead to a clogged filter, which would trap noxious fumes in the print chamber. Upon opening the printer, these fumes could be very potent. Failure to change the filter could also result in a loss of positive pressure in the print chamber, causing it to lose it's "clean-room-like" properties. Do not run the printer without a carbon filter installed.

 

  1. Remove four thumb screws by hand from the carbon-filter bracket. The bracket may be removed if you wish.

 

install-carbon-filter.jpg
  1. Remove the filter and discard it according to all local, state, and federal regulations.

WEAR 100% NITRILE GLOVES WHEN HANDLING A CONTAMINATED FILTER.

carbon-filter.jpg
  1. Inspect the new carbon filter to ensure that it is not damaged in any way or dirty. Install the filter inside the empty bracket.
install-new-carbon-filter-v2.jpg
  1. Secure the carbon-filter bracket in place with the four thumb screws.
install-carbon-filter.jpg

When Printer is Idle / Sleep Mode

When the printer is idle, be mindful of the following:

  1. Be sure to keep the printer lid closed to keep out dust and other debris, as well as to keep any fumes inside the printer.
  2. After a time, the printer will go into Sleep Mode: the touch screen will turn off, while the printer will remain turned on. You can wake up the screen by touching it.

    NOTE: The screen the printer fell asleep on will still be present, and will still register a button press if a button is active on the screen. It is recommended to touch the screen at the top when waking it up, since the buttons at the top are simply menu buttons, and accidental presses will not perform critical actions.

Running a Resin Tray Cleaning

Any time you experience a failed build, there will more than likely be partially cured resin either floating in the resin tray or stuck to the resin-tray film. Because of this, you must perform a Resin Tray Cleaning after a failed build, even if floating debris in the tray is not obvious. The following steps describe the process.

  1. Remove the print platform from the machine. This print does not need to adhere to the print platform and might be difficult to remove from the platform.
  1. On the printer, tap the settings-cog.jpg button to open the Settings screen. Tap the Resin Tray Cleaning Tool icon.
preferences-tray-cleaning.jpg
  1. You will see the screen at the right. Tap the Clean Tray button.
tray-cleaning-gui-1.jpg
  1. If you have not done so, remove the print platform. Ensure printer lid and front door are closed and tap Start.
tray-cleaning-gui-2.jpg
  1. The cleaning print will now begin. This build cannot be aborted, even if you open the lid and front door. It must complete once it is started. You will note there is a progress bar on the screen and a Remaining Time indicator. Once the build is finished, the printer screen will change. Tap Next Job to prepare the printer for the next build.

tray-cleaning-gui-3.jpg

  1. Wait at least one minute after job completion. Use the Resin Mixer to get under the printed sheet and remove it from the tray. Clean and cure the printed sheet so that you can discard it with regular trash.
flash-print-with-resin-bits-SA.jpg

Post Processing

Introduction

Once your 3D build has completed, the part on the platform is considered green until it has been through post-processing. A green part must be handled with nitrile gloves at all times. This section describes how to post-process the part, rendering it safe to handle without nitrile gloves. You will need lint-free paper towels (or absorbent cloth) to catch resin that may drip from the part, as well as two stainless-steel or glass containers in which to submerge the part in >90% alcohol solvent.

always wear 100% nitrile gloves during post-processing procedures.

CAUTION: Always follow the precautions noted in the SDS (Safety Data Sheets) for any resin or solvent being used. It is important to limit the exposure of the resin tray to light, as too much exposure will begin to solidify the resin inside it and render it unsuitable for part building. Place resin-tray cover over resin tray when not in use, close the printer door, or empty the material from the resin tray back into a material bottle of the same resin, sealing the bottle.

Remove Print Platform

  1. Allow the printed part to drain over the resin tray until resin stops dripping off the part. Once this is done, open the printer lid. You will see the screen below on the printer:

lid-open-after-job-complete.jpg

drip-over-print-tray-v2.jpg
  1. Wearing nitrile gloves, tilt the print platform over the resin tray such that any remaining resin is drained into the resin tray.
tilt-print-plat.jpg
  1. Place a paper towel or gloved hand under the part and lift the print platform out of the machine. The paper towel will keep resin from dripping on unwanted surfaces.

CAUTION: Do not remove the printed part from the print platform while both are still in the machine. Doing so risks getting partially cured print material in the resin tray, which will cause future builds to fail and/or cause the resin-tray membrane to puncture.

remove-print-plat.jpg
  1. If you have another print job in your 3D Sprint queue, or if you want to reprint the same job, you may now insert a clean print platform, as the screen in Step 1 suggests. Closing the printer lid at this time will show the screen at the right, whether you insert a new platform or not. You may now:
    1. Reprint the previous job
    2. Print the next job in your 3D Sprint queue. If there is no pending job in your 3D Sprint queue, you will not see the Next Job button.
reprint-or-next-job-screen.jpg

Remove Printed Parts From Platform

You must now remove the printed part(s) from the print platform to prepare them for cleaning.

WEAR 100% nitrile gloves whenever handling uncured or partially cured print material.

CAUTION: Ensure that any tools you use in post-processing have been cleaned since their last use.

 

  1. Put a nonabrasive cloth/lint-free paper towel underneath the print platform. Using the included punch tool, remove printed part from the print platform by pushing on it through the top side of the platform. Hold it the way you would a rubber stamp.

hole-puncher-hero.gif

  1. Once the parts are off the platform, rinse them in >90% alcohol solvent by hand, holding them over a container that can catch the solvent.
rinse-parts-off-platform.gif

Special Considerations for Elastomeric Resins

If you are running elastomeric resins, such as Ortho IBT or Gingiva Mask, it may be difficult to remove parts from the print platform using only the punch tool.

  1. Use the punch tool as described in Step 1 above. This will get the part started in detaching from the platform.
 
  1. Use the Platform Scraper to fully remove the part from the platform.
remove-elast-part.gif
  1. For instructions on removing the remaining, partially cured resin, see the section Clean Print Platform.
 

Cleaning Printed Parts

The following equipment is needed to clean parts produced on the NextDent 5100 Printer:

  1. Stainless steel or glass containers that are big enough to contain the printed parts you wish to make
  2. >90% alcohol solvent
  3. Ultrasonic cleaner, which agitates solvents like >90% alcohol solvent using ultrasonic sound waves. Sonication is the required cleaning method for your printed parts to achieve medical certification. Your ultrasonic cleaner should have:
    1. Digital Timer
    2. Volume great enough to hold your steel or glass containers
    3. Explosion-proof features

WARNING: >90% alcohol solvent is FLAMMABLE AS BOTH LIQUID AND VAPOR. KEEP AWAY FROM HEAT, SPARK AND OPEN FLAMES. USE WITH ADEQUATE VENTILATION. STORE AT 20-30ºC (68-86°F).

always wear gloves when cleaning build parts.

Cleaning Parts Using an Ultrasonic Cleaner

NOTE: Follow all safety precautions and guidelines set forth in the User Guide for the ultrasonic cleaner you have purchased.

Always wear 100% nitrile gloves whenever handling an uncured printed part, as well as when handling any solvent used to clean such parts.

Important Notice for Ortho IBT Resin

If you are running Ortho IBT resin, you MUST use Ethanol as your cleaning solvent. Do not use IPA.

Cleaning Procedure

While the User Guide for your ultrasonic cleaner will provide specific-use instructions, the steps outlined below describe how 3D Systems recommends cleaning build parts via an ultrasonic cleaner. 

  1. Label your steel or glass containers as "1st Bath" and "2nd Bath."
 
  1. Wearing nitrile gloves, place the printed part inside 1st Bath container. Pour >90% alcohol solvent into the container until you completely submerge the printed part. Used >90% alcohol solvent may be used for this first bath, unless it is completely saturated.

    NOTE: The same solvent may be used in the first bath to clean several printed parts. It will, however, become saturated over time and will no longer be effective at stripping uncured resin from printed parts. You must visually gauge this effectiveness each time you clean a part. If after washing, the printed part still has large amounts of uncured resin on it, you will need to discard the old solvent according to all local, state, and federal regulations. Then use new solvent for your next cleaning job.

 
  1.  Place 1st Bath container inside the ultrasonic cleaner.

CAUTION: Ensure that your ultrasonic cleaner is properly rated to use flammable solvents. Failure to do so could present a fire hazard.

put-parts-in-ultrasonic.jpg
  1. Follow the instructions in your ultrasonic cleaner's User Guide to power it on and begin cleaning. For this first bath, run the ultrasonic cleaner for 3 minutes.
 
  1. After the cleaning cycle has finished, remove the printed part from the ultrasonic cleaner using nitrile gloves. You may wish to use shop air or an air compressor to dry the part in between cleanings, as this is an effective method for getting one solvent off the part before cleaning it with another.
 
  1. For 2nd Bath container, follow Steps 2-5 once more. But the >90% alcohol solvent must be completely clean for the second bath (no other parts or printer components should have been cleaned with it). This time, run the ultrasonic cleaner for two minutes. After finishing Step 5 with 2nd Bath container, the part is ready for drying and post-curing in the LC-3DPrint Box.
 

 

CAUTION: Cleaning printed parts for any longer time than prescribed in this manual risks creating defects in the part.

Cleaning Crowntec Parts

Wear nitrile gloves and protective goggles whenever handling uncured parts.

  1. Remove the parts from the print platform using a putty knife.
  2. Remove excess material by wiping the parts with a lint-free cloth (or small brush) soaked in 96% alcohol solution. Clean the parts until all uncured material is removed.
  3. Dry parts thoroughly with an air syringe.

Dry the Build Parts

For information on the different methods for drying printed parts, please see the section Air-Drying Parts. Dry printed parts until you see no more liquid on their surfaces. For any drying method, please use the following guidelines:

  1. Always dry printed parts over a tub, lab paper towel, or absorbent cloth. Do NOT dry the part over a sink or tub that drains to normal wastewater.
  2. Discard any disposable towels used in the drying process according to all local, state and federal regulations. These towels have been in contact with uncured resin and solvents, and must be treated as such.
  3. On a regular basis, have a professional cleaning service wash any absorbent cloths used in the drying process.
  4. If you dry the part over a tub, periodically empty/clean it, discarding its contents according to all local, state, and federal regulations. The tub has been in contact with uncured resin and solvents and must be treated as such.
  5. If using an air compressor in the same room (as opposed to shop air), wear ear protection when it is in use.
  6. Always wear 100% nitrile gloves and safety glasses when handling partially cured printed parts. When drying with a high-pressure method, uncured resin or solvent may splash.
  7. If you come into contact with uncured resin during part drying or at any time, wash the affected area with soap and COLD water. Any clothes contaminated with uncured resin or solvent must be dry cleaned promptly.
  8. There might be remnants of supporting architecture left on your part(s). You can remove these supports by hand in the majority of cases. If you experience any issues removing supports, please see Troubleshooting item PCI4.
    dental-supports-061520181727.jpg →dental-supports-v2-061520181730.jpg

UV Cure the Parts

  1. After the part is completely dry, insert the part into the middle of the LC-3DPrint Box. If there are multiple parts, ensure there is some space between them on the oven platform. It is necessary to use the LC-3DPrint Box as your UV oven, as it has been tested specifically for the NextDent resins that are used to build certified medical devices. Ideal, tested curing times are outlined in the Resin Stirring and Curing Chart in the "Operation" section of this manual.

    CAUTION: Use nitrile gloves whenever touching or operating the LC-3DPrint Box. Normal usage of the box will most likely get uncured resin on the box handle and buttons; so it is always best to take this precaution. Also, the printed parts are still "green" at this stage, not yet fully polymerized and not safe to touch without gloves.

lc-3d-print-box.jpg

 

  1. Follow instructions in your UV oven instruction manual to begin the post-curing process. If you have the LC-3DPrint Box, the instruction manual can be found both in the packaging or by downloading the link here: NextDent LC 3D-Printbox Instructions for Use.
  2. Please see the Resin Stirring and Curing Chart in the "Operation" section of this manual for resin curing times. Do not open the curing chamber door until the curing process has been completed. The LC-3DPrint Box has a sensor that will turn the machine off during curing if the lid is open. Please see the User Guide of the resin you are using for full post-curing instructions. These guides are linked to in the section NextDent Material Documentation.

    CAUTION: Be careful not to over-cure the part. Over-curing can cause discoloration and part warping.

  3. Once the printed part has been fully cured, remove the part from the UV oven, using nitrile gloves when opening and closing the oven.
  4. The printed part is now safe to touch without nitrile gloves.

Clean Print Platform

CAUTION: Do not clean the print platform or resin tray in a sink or tub that drains into wastewater. These components must be cleaned in a self-contained tub and the solvent/resin mix must be discarded according to all local, state, and federal regulations.

WEAR 100% nitrile gloves throughout this procedure.

Clean Print Platform

You must clean the print platform after each use.

  1. Use the punch tool to punch out the bits of supporting architecture that are inside the holes. Punch in a column, going up an down until you have run the punch tool through every hole. See the punching pattern below for reference.

punch-tool-pattern.gif

scrape-supports-(2).jpg
  1. Use the Platform Scraper to scrape cured resin off the underside of the print platform. If you are running Ortho IBT or Gingiva Mask, please see the section below, Special Consideration for Elastomeric Resins.
clean-print-plat-dental-tool.jpg
  1. You should have the platform-cleaning fixture in a tub with >90% alcohol solvent. Place the print platform on the fixture, being sure it is submerged in the solvent, and use the punch tool up and down on the platform once more, as you did in Step 1.

print-platform-stand.jpg

Platform-cleaning fixture

clean-print-plat-ipa.jpg
  1. Wipe down the platform with a lint-free paper towel or nonabrasive cloth.
wipe-with-paper-towel.gif
  1. Inspect the platform, particularly the holes on the flat surface, to ensure no partially cured resin remains. If you find resin or partially cured bits on the platform at this point, follow the steps in this section again on the problem areas.

Your print platform is now clean and ready to be reused.

Special Considerations for Elastomeric Resins

For cleaning print platforms that run elastomeric resins such as Ortho IBT or Gingiva Mask, your printer package includes a Wire Brush accessory. The following instructions demonstrate how to use this brush.

  1. Use the Platform Scraper to remove as much partially cured resin as you can.
remove-elast-partially-cured.gif
  1. Identify all areas of the platform with partially cured resin and use the Wire Brush to scrape off as much as possible.
use-wire-brush-no-solvent.gif
  1. Turn the print platform over and use the Wire Brush to scrape all areas that have partially cured resin.
use-wire-brush-no-solvent-top.gif
  1. Place the print platform in solvent and use the Part-Cleaning Brush to clear away areas of liquid resin.
use-part-cleaning-brush.gif
  1. Use the Punch Tool if desired to punch bigger chunks of material through the platform. Use the Wire Brush to scrape the remaining partially cured resin from the platform
use-wire-brush-in-solvent.gif
  1. Wipe down the platform with a lint-free paper towel or nonabrasive cloth.
wipe-with-paper-towel.gif
  1. Inspect the platform, particularly the holes on the flat surface, to ensure no partially cured resin remains. If you find resin or partially cured bits on the platform at this point, follow the steps in this section again on the problem areas.

Clean Resin Tray

You must clean the resin tray if:

  • You believe the resin tray has debris in it.
  • You are using a new bottle of the same print material AND that bottle has a different batch number than the previous bottle.

    CAUTION: Do NOT mix identical print materials from bottles with different batch numbers, as any issues with the material must be traceable to a specific batch number. Mixing batches makes this impossible to track.

  • You are using a different print material in the same resin tray, according to the section Resin Tray Material Cross-Usage.

Every time you remove the resin tray for any reason, you should also inspect/clean the catch tray, as in the section Clean/Replace the Catch Tray.

NOTE: The elevator must be at its upper limit and the print platform must not be in the printer during this procedure.

NOTE: Two iterations of this process tends to be enough for a fully cleaned resin tray. If you find that you need to repeat this process more than once, consider spending more time brushing the membrane/tray when soaked in >90% alcohol solvent.

NOTE: Avoid touching the bottom of the membrane during this procedure. If resin is observed on this surface, spot clean with >90% alcohol solvent by squirting/pouring solvent on the area with uncured resin. Finish by drying with compressed air. Do not touch Part-Cleaning Brush or any other tool to the bottom of the membrane.

Procedure

  1. Push in the tension-arm release lever and lift tension arm.
  2. Using nitrile gloves and using both hands, slowly lift the resin tray out of the printer.

CAUTION: Take care not to hit the resin tray on the elevator arms, printer lid, or other printer components during removal.

clean-resin-tray-1.jpg
  1. Pour the contents of the tray over the tray corner into your hazardous waste container. The Resin Mixer may be used to guide print material and debris out of the tray.

CAUTION: Do NOT pour the resin back into the bottle. Doing so risks contamination, and/or improper mixture, of material in the bottle. This could result in undesirable build quality and/or build failure.

CAUTION: Do NOT use the Platform Scraper to clean the resin tray, as it will easily puncture the resin-tray membrane.

clean-resin-tray-2.jpg

clean-resin-tray-3.jpg

  1. Place resin tray in its garage.

TIP: You may place a paper towel or clean-room wipe on your cleaning surface, so as not to get print material and/or solvent directly on it. This can also prevent foreign debris from dirtying or puncturing the tray's membrane. If you use this tip, be sure to discard the paper towel/wipe according to all government regulations after each cleaning.

clean-resin-tray-5.jpg
  1. Pour approximately 250 mL of >90% alcohol solvent into resin tray and use the Part-Cleaning Brush to gently agitate the resin on the membrane and tray edges.
  2. After brushing all surfaces that were in contact with resin, discard dirty solvent according to all government regulations.
  3. Rinse the resin tray with clean >90% alcohol solvent and discard solvent according to all government regulations.

spray-ipa-on-tray.gif

wipe-ipa-inside-tray.gif

  1. Dry membrane gently with 30 psi dry compressed air using an air gun attachment, or allow tray to air dry.

spray-ip-on-tray-2.gif

  1. If uncured print material remains within the tray, repeat steps 5-8.
  2. If uncured print material remains on the outer edges of the resin tray:
    1. Wipe clean with a lint-free paper towel soaked with >90% alcohol solvent (~15mL). Dispose of used paper towels and gloves discard according to all government regulations.
    2. Dry membrane gently with 30 psi dry compressed air using an air gun attachment, or allow tray to air dry.
clean-resin-tray-9.jpg

spray-ip-on-tray-2.gif

  1. Inspect the resin tray to ensure no uncured resin and/or foreign debris remain.

spray-ip-on-tray-2.gif

  1. Discard all paper towels/wipes used throughout this procedure according to all government regulations.

The resin tray can now be stored in the Resin-Tray Garage or filled with new print material for printing, according to the section Resin-Tray Material Cross-Usage.

clean-resin-tray-10.jpg→resin-tray-garage-05012018.jpg

You can also store the resin tray in the printer with the cover from the garage on top, as seen below.

resin-tray-lid-in-machine.jpg

Clean Finishing Tools

It is necessary to clean any tools you used during post-processing before their next use, even if you are continuing to use the same resin. Items to be cleaned include:

  1. Punch Tool
  2. Resin Mixer
  3. Platform Scraper
  4. Part-Cleaning Brush
  5. Your own dental tools

To clean any of these items, you can either soak them in >90% alcohol solvent or place them into a beaker of >90% alcohol solvent and put them in an ultrasonic cleaner. Ensure that they are completely dry before their next use, either by using compressed air or letting them air dry.

CAUTION: Before performing any preventative maintenance procedures, power the printer down using the power switch on the back and disconnect printer power by unplugging the power cord from the back of the machine.

Cleaning the Printer

Frequency: Monthly

The external and internal parts of the printer should be cleaned according to the guidelines in the following sections. Here is a quick overview:

  1. Clean the flooring/walls/surfaces around the printer with >90% alcohol solvent to ensure that any resin drips have been wiped up. For cleaning dust and other debris, use a small vacuum or other method that does not release particulates in the air.
  2. Clean the outside printer frame, EXCEPT FOR THE LID, with >90% alcohol solvent and a nonabrasive cloth. Please see the section Inspect Printer Lid for instructions on cleaning the printer lid.
  3. Use >90% alcohol solvent and a nonabrasive cloth to clean elevator arms.
  4. The following sections will give instructions on how to remove and clean more-specific parts of the printer. Please review all sections before cleaning your printer to ensure you are properly cleaning each component.

Clean/Replace the Catch Tray

Remove and Clean the Catch Tray

Frequency: Weekly

Remove the catch tray and clean it of dust or any drops of resin with a clean-room wipe and 90% Alcohol Solution as described below.

If there has been a significant leak from the resin tray, replace the resin tray and install the new catch tray that came with the new resin tray.

CAUTION: Do not attempt to use a catch tray after it has captured a significant spill of resin.  It can be difficult to clean the glass well enough to ensure perfect transmission of the UV radiation to ensure good print quality.  Instead, replace the catch tray. 3D Systems is not responsible for print quality failures due to a contaminated catch tray. Do not attempt to clean the catch tray while it is still inside the printer. The cleaning methods discussed below could cause damage to printer components if attempted inside the printer.

ALWAYS WEAR 100% nITRILE GLOVES WHEN HANDLING THE CATCH TRAY, EVEN IF IT APPEARS THERE IS NO RESIN ON THE OUTSIDE OF IT. Getting fingerprints or other debris on the catch-tray GLASS can degrade print quality. remove/Hold the tray with both hands and upright to prevent spilling.

 

  1. Carefully pull the catch tray toward you until it comes off its track. Keep the tray upright at all times while pulling it out of the machine.

remove-catch-tray.jpg

  1. If the catch tray glass is visually clean of dust and resin drips, skip to the section Replace the Catch Tray below. If the catch-tray glass has normal dust or other debris on it, proceed to Step 3. If only the catch-tray reservoirs have resin in them, proceed to Step 4. If the catch-tray glass only has a few drops of print material on it, proceed to Step 5.

CAUTION: Do NOT reuse print material that has spilled into the catch tray. Spilled material is no longer viable for printing, as contaminates could have mixed with it.

 
  1. You may use any of the following methods to clean dust or other debris off the catch tray:
    1. Use shop air to blow debris off both sides of the catch-tray glass. Be sure you clean both sides.
    2. Use a non-ammonia-based glass cleaner and a nonabrasive cloth to remove finger prints or other debris that is not print material. Be sure to clean both sides of the glass. After cleaning, use shop air or give the glass plenty of time to air dry before reinstalling.
  2. To clean spilled resin in the catch tray and discard it:
    1. Pour out and discard the resin in the catch tray according to all government regulations.
    2. Hold the catch tray over a drip pan and squirt 90% Alcohol Solution into the catch tray, tilting the tray so that all waste material comes out.
    3. Use a nonabrasive cloth or lint-free paper towel to dry the inside of the catch tray.
    4. Discard the catch tray and all waste products according to all government regulations.
clean-catch-tray-glass.jpg
Catch tray with clean glass

 

  1. To clean spots of resin on the catch-tray glass:
    1. Pour >90% alcohol solvent onto a nonabrasive cloth such as a clean-room wipe.
    2. Wipe the glass inside the catch tray until no more resin exists.
    3. Turn the catch tray over and, using a new cloth sprayed with 90% Alcohol Solution, wipe the glass on the bottom of the catch tray.
    4. Use shop air or give the glass plenty of time to air-dry before reinstalling.
  2. Inspect the catch tray, ensuring that the glass plate has not detached or become damaged during cleaning.

clean-catch-tray-2.gif

clean-catch-tray-3.gif

Replace the Catch Tray

Use the following instructions to reinsert the catch tray into the printer or to install a new catch tray.

CAUTION: Operating the printer without a catch tray installed risks getting material on the print-engine components, and risks over-curing of the printed parts, as the projector's radiation is filtered slightly by the catch-tray glass. Printing without a catch tray installed will also slightly alter the size of printed parts.

 

  1. Line up the catch tray on the rails.
catch-tray-follow-rails.jpg
  1. Hold up the catch tray, flush with the underside of the chassis, and push it toward the back of the printer until it stops at the back of the rails. See the picture below for the correct orientation to install the catch tray.

catch-tray-orientation.jpg

replace-catch-tray.jpg
  1. Push gently against the front of the catch tray to ensure that it does not go back any more and is fully seated in the machine.

Clean Resin Tray

Frequency: When changing materials, or monthly if using same material

Please follow the instructions in the section Clean Resin Tray to clean it.

CAUTION: Failure to clean the resin tray regularly risks having partially cured resin bits in the tray, which can cause resin-tray membrane punctures and build failures.

Clean Tension System

Frequency: Monthly

To clean the tension latches on the left and right sides of the chassis:

WEAR 100% nitrile gloves throughout this procedure.

 

  1. Untension the resin tray and carefully remove it. Place it in the resin-tray garage with the lid on.

print-tray-garage-v2.jpg

release-manual-tension-arm-v9.gif
  1. Remove both vanity covers from the printer chassis. Clean the vanity covers with a nonabrasive cloth and 90% alcohol solution.
remove-vanity-covers.jpg
  1. Pour 90% alcohol solution on a nonabrasive cloth. Clean both latches and inspect them for any signs of damage. If there is damage, contact your reseller.
clean-tension-latches-1.jpg
  1. Clean the top and bottom of the tension arm itself with 90% alcohol solution. Inspect the tension arm for any signs of damage. If there is damage, contact your reseller.
  2. Reinstall the vanity covers over the chassis.
top-and-bottom-tension-arm.jpg

Cleaning of the tension system is now complete.

Clean Membrane Interface Lip

Frequency: Weekly

The membrane interface lip is pictured below. It is the part of the chassis that makes contact with the resin-tray membrane.

membrane-interface-lip.png

If the lip has dust, debris, or resin on it, clean it with >90% alcohol solvent and a nonabrasive cloth. Inspect the lip for any damage, as chips or cracks could affect the tension of the resin-tray membrane during printing.

Clean Touch Screen and QR-Code Scanner

Frequency: Monthly
  1. Ensure that the printer's touch screen does not have resin, dust, or other debris on it. If it does, pour >90% alcohol solvent on a nonabrasive cloth and wipe the screen down.
gui-(2).jpg
  1. Ensure that the QR-Code Scanner's window does not have resin, dust, or other debris on it. If it does, pour >90% alcohol solvent on a nonabrasive cloth and wipe the screen down. You will not have access to clean behind the scanner's window. If you see that resin and/or debris has gotten inside the scanner window, contact your reseller.
qr-code-scanner-(2).png

Inspect and Clean Printer Lid

Frequency: Monthly

Inspect Dust Seals

There are strips of dust-sealing material around the underside of the printer lid. These strips must remain intact to avoid dust and other debris entering the print chamber. There are seven strips in total, as indicated below. If ANY of these strips is damaged or removed, cease printing until the strip is replaced. print-lid-dust-sealers.jpg

Inspect Printer Lid for Damage

Ensure that there is no damage to the printer lid that could hinder the printing process. Normal scratches are okay. Look for:

  1. Cracks in the lid's plastic. Any cracks could expose the printing area to ambient UV light, which could affect part quality and could also cure material in the resin tray.
  2. Breaks that do not allow the lid to close completely. If the lid does not fully close, the printing area could be exposed to ambient UV light.
  3. Breaks that do not allow the lid to stay open when lifted. This type of break will make many print processes more difficult and prone to error.

If any of these conditions is found to exist, contact your reseller for replacement information.

nextdent-lid-closed.jpg

Clean Lid

The outer surface of the lid should be cleaned monthly or as often as necessary to maintain an acceptable appearance.  The printer lid is made of acrylic and must be cleaned with a specialty product such as Novus No. 1 or Brillianize.  A mild solution of soap or detergent and water can also be safely used. NEVER use window-cleaning fluids with ammonia (such as Windex or Formula 409), gasoline, denatured alcohol, carbon tetrachloride, or acetone, which will cause the acrylic to crack. It is best not to have a print platform or resin tray installed during lid cleaning, so as not to contaminate either with the cleaner you are using. During the cleaning cycle, verify that the hinges move freely. If the hinges are binding, contact your reseller.

  1. Apply the cleaning product with a damp, nonabrasive, lint-free cloth. Using a microfiber cloth or cellulose sponge is also acceptable.
  2. Rinse with a nonabrasive cloth and clear, clean water.
  3. Blot-dry with a chamois, damp cellulose sponge, or microfiber cloth to prevent water spotting

NOTE: Grease, oil, and tar may be removed with a good grade of hexane, naptha or kerosene. Be sure to wash these solvents off quickly to prevent damage to the acrylic.

Inspect Projector Lens and All Cables

Frequency: Every two weeks
  1. Ensure that the power cable is in good shape. If the cable is damaged and/or any wiring is exposed, cease use of the printer and order a new power cable.
   
  1. Ensure the Ethernet cable is in good shape and that it still connects tightly on the network port of both the printer and your Ethernet outlet. If this cable is damaged and/or wiring is exposed, cease use of printer and replace Ethernet cable.

Inspect the area around both wired connections for dust collection and other debris. Keeping these areas clean will prevent a static hazard and potential damage to the printer.

 
  1. Clean the projector lens every two weeks or as needed. Use a clean-room swab and >90% alcohol solvent to wipe the projector lens of any dust. Be sure to wet the clean-room swab with the alcohol, rather than squirting it directly onto the lens. Wear 100% nitrile gloves whenever handling >90% alcohol solvent.

CAUTION: Do not use the printer if resin has spilled onto the projector, rather than just the lens. Do not attempt to clean the projector. Contact your reseller immediately.

Check Printer Level

Frequency: Every three months

Check that the printer is still level relative to the chassis, whether it is on the pedestal or not.

Place bubble level on chassis, as seen at the right. If the bubble is not in the center of the circle, follow the steps in the section Level the Printer on Pedestal.

level-printer-via-elevator-v3.jpg

Check Print Platform Level

Frequency: As needed

If the print surface on the print platform is not level, it will affect the quality of your builds and may even lead to build failure. If a print platform is not level, it cannot be reliably bent to be made level and must be discarded according to all government regulations. This section describes how to identify the two ways in which your platform might be bent.

Identify a Convex Print Platform

  1. Place the print platform, print-surface down, on a level surface.
  2. Place a spacer of some kind that is between 0.5mm - 0.75mm thick (such as a credit card, shim, or washer) on the same level surface next to the platform.

    NOTE: This test will be more accurate the closer your spacer is to 0.5mm.

  3. Slide the spacer against one corner of the platform and ensure that the spacer does NOT fit underneath. If the spacer does fit underneath, the platform is convex on that corner.
test-convex-platform.jpg
  1. Perform this check for each corner of the platform. If the spacer fits under any corner, the platform is convex and must be discarded.
test-convex-platform-2.jpg

Identify a Concave Print Platform

  1. Obtain a small spacer between 0.5mm - 0.75mm thick, such as a round shim or washer. Place the spacer on a level surface.
  2. Place the print platform, print-surface down, on top of the spacer such that the spacer is in the center of the platform.

test-concave-plat-1.jpg

Shown upside-down for clarity

  1. Gently push down on each of the four sides of the platform, one-at-a-time, and ensure that the platform rocks in the direction you are pushing. If the platform does NOT rock, it is an indication that the platform surface is concave.

concave-plat-good-test.jpg

Good test - the platform tilts and is NOT concave. It may be reused.

 

concave-plat-bad-test.jpg

Bad test - the platform does not tilt and is concave. It may NOT be reused. Platform bend in this image is exaggerated for clarity.

Printed Part Quality

# Issue Description Customer Troubleshooting Steps
PPQ1 Part not accurate in the X/Y direction Run the Accuracy Wizard in 3D Sprint, as seen in the section Accuracy Wizard.
PPQ2

Delamination between layers - this is separation of printed layers, which do not cure together properly

delamination.jpg

This can be caused by:

  1. Not enough material in the resin tray. To prevent this, be sure to fill material back up to the minimum level specified in this guide before building.
  2. Cured material or other debris caught in between layers. Run cleaning print.
  3. The part orientation on the print platform can contribute to delamination. Please see the section 3D Sprint Part Orientation Guide to find out the best way to orient your part.
  4. Spilled print material or other debris gets in between the projector's radiation path and the print surface. In this case, remove the resin tray and catch tray and inspect them for spots of resin.
    1. Clean the resin tray, as in the section Clean Resin Tray.
    2. Follow the guidelines in the section Clean/Replace the Catch Tray to determine if your catch tray needs to be cleaned or replaced. 
    3. Follow the guidelines in the section Inspect Projector Lens and All Cables to determine if you can clean your lens, or if the resin spill is too wide-spread to clean with simple means.

      CAUTION: Do not attempt to clean anything in the lower print chamber outside of what is listed in this guide. Doing so risks further damage to the printer. For large resin spills, contact your reseller immediately.

PPQ3 Voids in printed part - holes or empty spaces where there shouldn't be

This can be caused by:

  1. Not enough material in the resin tray. To prevent this, be sure to fill material back up to the minimum level specified in this guide before building.
  2. Spilled print material or other debris gets in between the projector's radiation path and the print surface. In this case, remove the resin tray and catch tray and inspect them for spots of resin.
    1. Clean the resin tray, as in the section Clean Resin Tray.
    2. Follow the guidelines in the section Clean/Replace the Catch Tray to determine if your catch tray needs to be cleaned or replaced.

        pry-part-off-film.gif

        CAUTION: Putting too much pressure on the resin-tray film can puncture the film. Be mindful of this during cleaning. The film cannot be replaced by itself; if the film is damaged, the whole resin tray must be replaced.

      3. Clean the resin tray as described in the section Clean Resin Tray.

PPQ4 Part color is incorrect

Any one of the following could be the cause:

  1. Resin was not mixed in the bottle before pouring - Be sure to mix/stir the resin before printing according to the section Mixing, Stirring, and Curing Chart.
  2. Resin was not stirred in the resin tray before printing - Be sure to mix/stir the resin before printing according to the section Mixing, Stirring, and Curing Chart.
  3. A combination of both 1 and 2 - Be sure to mix/stir the resin before printing according to the section Mixing, Stirring, and Curing Chart.
  4. You may have poured the wrong resin - Ensure that the resin you pour in the resin tray is from the same bottle you scanned.
  5. You may have over-cured or under-cured the part - Ensure the part is cured as recommended in the Resin Stirring and Curing Chart.
  6. You may not have cleaned the resin tray well enough before changing from one pigmented resin to another.
PPQ5 Part does not adhere to the print platform

This could be caused by:

  1. Dirty projector lens - Clean the lens according to the section Inspect Projector Lens and Cables.
  2. Dirty catch-tray glass - Clean the glass according to the section Clean/Replace the Catch Tray.
  3. Debris on the print platform - partially cured resin from a previous build or other debris could prevent adhesion. Ensure you clean the print platform between each build as in the section Clean Print Platform.
  4. Damaged or bent platform. Contact support.

Hardware Issues

WEAR 100% NITRILE GLOVES WHENEVER HANDLING RESIN OR SOLVENTS

 

# Issue Description Customer Troubleshooting Steps
HW1

Resin cures in the resin tray from ambient light sources.

cured-resin-in-the-print-tray.jpg

Ensure that you do not stage the printer in an area where it will be exposed to the following: Sunlight (even through windows), quartz-halogen lights, high-intensity incandescent lights, and other UV-intensive lighting. To clean cured resin out of the resin tray:

  1. Remove the resin tray from the machine.
  2. If cured resin is on the upper lip of the tray, as in the picture at the left, use the Resin Mixer to scrape the cured material off.
  3. If cured resin is in the main part of the tray, it will likely be floating on top as a thin film. You should be able to lift this film out wearing nitrile gloves. If you are printing with Gingiva Mask, the cured resin will be at the bottom of the tray. You should be able to remove this cured resin with the resin mixer.

In either case, you must discard the rest of the resin in the resin tray, as you will not have a way of knowing the amount this resin has cured. Discard the resin according to all government regulations.

HW2 Resin Tray membrane is punctured or otherwise damaged. The resin tray will have to be replaced. Contact your reseller to order more trays. It is a good idea to have at least one extra tray on-hand to reduce printer downtime.
HW3 Elevator Arms are loose If elevator arms appear to be loose when placing a print platform on them, gently push on the arms in multiple directions to see if they shake. If they do, contact your reseller immediately. The printer will need to be sent in for repairs.
HW4 Resin spills inside machine

Resin spills in different parts of the machine will require different actions by the printer operator. Please find the scenario that matches your spill below:

  1. Spilled resin is contained in the catch tray reservoirs, and no resin is on catch-tray glass - Remove the tray and dispose of the resin in the tray according to all government regulations. Rinse the catch tray out with >90% alcohol solvent and re-install in machine.
    catch-tray-reservoirs.jpg
  2. Spilled resin hits the catch-tray glass - Follow the guidelines in the section Clean/Replace the Catch Tray to determine if your catch tray needs to be cleaned or replaced.
    catch-tray-glass.jpg
  3. Spilled resin hits projector lens - Follow the guidelines in the section Inspect Projector Lens and All Cables to determine if you can clean your lens, or if the resin spill is too wide-spread to clean with simple means.
    no-resin-on-lower-build-chamber.jpg

    CAUTION: Do not attempt to clean anything in the lower print chamber outside of what is listed in this guide. Doing so risks further damage to the printer. For large resin spills, contact your reseller immediately.

  4. Spilled resin hits components of the upper build chamber - If the resin has spilled on the orange lid (A), do NOT use >90% alcohol solvent. Clean the lid according to the section Inspect Printer Lid. If the resin has hit any other component (B) besides the orange lid, clean the spill with >90% alcohol solvent and a nonabrasive cloth.
    upper-printer.jpg
HW5 Resin spills outside machine

Resin spills outside the machine will require different actions by the printer operator. Please find the scenario that matches your spill below:

Porous surfaces - These are surfaces that will absorb liquids. Examples of porous surfaces are: carpeting, unfinished wood, certain stone tiles/counters. It is not recommended to stage the printer on surfaces such as these, as resin cannot be reliably cleaned out of them. If resin spills on these, the recommendation is replace the affected sections of the surface.

Non-porous surfaces - These are surfaces that will absorb little or no liquid. Examples of non-porous surfaces are: metal, glass, hard plastic, concrete, and finished wood. To clean spills on these surfaces, use paper towels to soak up as much resin as possible. Use >90% alcohol solvent and paper towels to clean residual spilled resin. Discard all spilled resin and cleaning materials according to all government regulations.

HW6 Touch screen touch input not working There may be resin buildup on the screen. Clean the screen with >90% alcohol solvent and a nonabrasive cloth.
HW7 Machine makes noise; but touch screen is blank or off
  1. GUI computer might be frozen. Unplug printer and leave unplugged for 30 seconds. Plug printer back in and turn on.
  2. If Step 1 does not work, contact your reseller immediately. The printer will have to be sent in for repairs.
HW8 Tension arm does not fully close
  1. Ensure that the vanity plates are properly seated on the chassis. Pay particular attention to the rear piece that partially covers the elevator.

  2. Ensure there is nothing obstructing the underside of the tension arm or the top of the chassis.

  3. Ensure that the tension clamps move freely and are unobstructed.

ts-tension-arm-wont-close.jpg

HW9 Printer Lid does not close Ensure that the tension arm is fully closed. If the arm is raised or simply not fully locked into place, the lid will be hard to close or may not close at all.
HW10 Printer Front Door does not close
  1. Ensure that the catch-tray access door (1) is fully closed. If the catch tray is not fully seated, this door cannot close- thus, the front door cannot close, either. Ensure that the catch tray is pushed all the way back.
  2. Ensure there are no obstructions blocking the door from closing.

lower-chamber-hero-best-dental.jpg

HW11 Elevator Arms unable to lower the Print Platform onto the Resin Tray's membrane surface
  1. Ensure that the print platform is seated correctly on the elevator arms, with the triangular grooves of the platform fitting around the conical pins on the elevator arms. Ensure that no built-up resin or other debris are preventing this from happening.
  2. Ensure that there is nothing obstructing the sides or back of the elevator spine that limits the motion of the elevator arms.

install-print-plat-04242018.jpg

HW12 Barcode on bottle not scanning/Printer asks to "select previously scanned bottle"
  1. Ensure the QR code on your bottle is clear and does not have resin or other material on it that obstructs it.
  2. Ensure the QR code scanner's window is clean of dust and debris.
  3. Ensure your printer has an active internet connection. Scanning data is sent to a 3D Systems server for validation and the scanner will not operate correctly offline or on a closed network.
  4. The printer might not be able to contact the QR-code-scanning server. Contact your network administrator and have him/her white-list the address mqg.3dsystems.com.

Part Cleaning Issues

# Issue Description Customer Troubleshooting Steps
PCI1 Parts come out of cleaning process dirty, shiny, or sticky.
  1. Parts may not have been properly cleaned. Ensure you have followed all the steps in the sections under Cleaning Printed Parts.
  2. Parts may not have been cleaned soon enough after printing. Be sure to clean your printed parts within 24 hours of the print job finishing.
  3. Solvent baths may need to be changed.
PCI2 Parts show surface cracks or edge erosion during sonication cleaning.

Your particular print material may be sensitive to sonication power. Reduce the power of your ultrasonic cleaner; reduce the duration of sonication; or, reduce the temperature of the cleaner's tank.

PCI3 Parts crack downstream after post curing.
  1. Parts may have been overexposed to solvents during cleaning. Ensure that you clean printed parts no longer than the times specified in the section Cleaning Parts Using an Ultrasonic Cleaner.
  2. If your cleaning times were correct, there are other cleaning parameters that you can try changing:
    1. Reduce sonication power.
    2. If your ultrasonic cleaner's power setting cannot be changed, reduce cleaning time.
    3. Reduce temperature of liquid in ultrasonic cleaner.
    4. Increase drying time after cleaning.
PCI4 Supporting architecture not completely removed by hand
  1. Ensure that for future builds, you have removed the supporting architecture before post-curing the part(s). The post-curing process makes the supports stronger and, therefore, harder to remove.
  2. Use tools such as flat snips and/or tweezers to remove support remnants from tight areas of your part.
  3. Perform wet-sanding with >90% alcohol solvent on support remnants.

Network Issues
