Safety Guidelines

General

The 3D printer system is designed with built in safety features, improper use can cause injury to personnel.

Follow these safety guidelines when operating the printer:

• Read and follow all 3D printer system instructions. Printer should only be operated by trained personnel.

• Follow all safety rules and heed all cautions and warnings in this guide.

• Do not attempt to open top door while printing.

• Do not use any material without reviewing the Global Harmonized Standards/Safety Data Sheet (GHS/SDS).

• Dress power and communication cables behind printer to prevent tripping.

• Do not attempt to access, service, or adjust printer components or perform procedures without reviewing the documentation for user accessible maintenance routines unless specifically trained to do so.

• Only certified service personnel that have completed the 3D Systems service training may perform tasks they are authorized and certified to complete.

• Do not ignore warning signs posted during 3D printer system service operations. If an error message appears on the 3D printer system’s User Interface refer to “Troubleshooting Section” within this guide depending on the error, before resuming operation.

• To prevent potential skin irritation and sensitization due to contact with waste material or uncured Part Material, follow all guidelines in the following sections.

Protective Equipment/First Aid 

Follow recommendations for protective equipment and general first aid procedures to minimize the risks from part material exposure. If professional medical attention is necessary, take the Global Harmonized Standards/Safety Data Sheet (GHS/SDS) for the exact material involved to the attending physician.

	Always wear 100% nitrile gloves and lab coats when handling any part or waste material. Latex gloves are not chemical-resistant and are not recommended.
	In the event of a leak or spill of uncured part material, wear safety glasses with side shields to provide eye protection.
	Because of the 3D printer system’s built-in engineering controls, respiratory protection is not necessary during normal operation. A NIOSH-approved (or equivalent) dust mask is recommended when dry sanding cured material parts.
	Always wear protective sleeves or a lab coat when doing anything around the materials. When skin comes in contact with materials they can cause an allergic reaction that can be harmful to skin.

Skin Contact

Uncured part material is a sensitizer, and can cause allergic reactions if skin comes into contact. When handling any part or waste material, always wear 100% nitrile gloves and lab coats.

Should skin come into contact with uncured part material, wash thoroughly with soap and cold water and immediately remove contaminated clothing and shoes. Do not use hot water or solvents to wash hands, as it will result in absorption through the skin. If skin is irritated, seek medical attention. Dry-clean contaminated clothing and discard contaminated shoes and leather products in accordance with applicable regulations.

Eye Contact

Safety goggles with side shields should be worn to prevent accidental splashes into the eyes. If 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 3D printer system.

Contact Lenses

Wearing contact lenses is not recommended if handling liquid materials. If material splashes into eyes when contact lenses are worn, flush eyes immediately with water. Verify that flushing has removed the contact lens from the eye(s). Protect eyes from light and obtain immediate medical attention. Discard contact lenses that come into contact with liquid material.

Fume Inhalation

Under normal operation, inhalation is not an expected route of entry. Always work in a well ventilated area when using materials and avoid breathing vapors. If inhaled, remove the personal to fresh air. Give artificial respiration or cardiopulmonary resuscitation (CPR) if required. If breathing is difficult, give oxygen. Obtain immediate medical attention.

Ingestion

Uncured part material is toxic if ingested. Obtain immediate medical attention.

Hygienic Practices

Because uncured material is toxic if ingested, it must not be present where food and drink are stored, prepared, or consumed. After handling materials, wash hands with soap and cold water before consuming meals, breaks, smoking, applying cosmetics, using toilet facilities, and after work.

Employees should be alerted of the need to clean and rinse off any contacted surface promptly in order to prevent further contamination. Ensure a convenient washroom location is provided with access to soap, water, and disposable paper towels.

Tools contaminated with part material should be cleaned prior to reuse. Solvents such as denatured alcohol or Isopropyl Alcohol (IPA), are normally required to clean equipment and tools. Wash with soap and water to remove any traces of excess part material or solvent.

Material Handling and Safety

Prior to using the ProJet® MJP 2500 and 2500 Plus,  users should be aware of potential hazards which may result in exposure to uncured part material, such as removal of the material waste bag and handling part material cartridges.

Emergency (GHS/SDS)

Chemtrec USA (800) 424-9300; Europe +1-703-527-3887

Consult the materials Global Harmonized Standards/Safety Data Sheets (GHS/SDS) for information on specific materials. For further information on this and related topics, consult the 3D Systems - Materials website at http://www.3dsystems.com/support/materials/msds.

Packaging Inspection

The material cartridges are packaged in shipping cartons. Upon receipt of material shipments, inspect cardboard carton exterior for signs of damage and leakage. If leakage is observed, DO NOT open carton, and contact 3D Systems’s Technical Support Hotline. 

ProJet® MJP 2500W	ProJet® MJP 2500 IC	ProJet® MJP 2500W

Storing a Partially Used Material Cartridge

It is important not to lay material cartridges that are partially used on their side. Doing so will cause material to seep through the vent cap and clog cap. This will cause damage to the material cartridge if used for a later print. To store a partially used Material Cartridge, place it upright in a ProJet® 2500 Cartridge Holder and tighten the vent cap.

Recertification Date

Always check material "Recertification Date" before use. If the cartridge has reached its Recertification Date, your 3D Systems certified Partners or 3D Systems Technical Support can assist with questions on material requiring recertification.

Disposal

Support Material 

Support material has no known regulatory requirements and may be disposed of in ordinary office waste.

Spilled Material

Spills of material are unlikely, and should NOT occur in normal operation of the 3D printer system.

Spills of support material can be cleaned without the use of protective gear, and disposed of as office waste.

Promptly remove spilled materials, dispose of waste materials, and clean up materials per local regulatory requirements. Small spills of uncured liquid part material can be cleaned up using disposable towels, non-reusable rags, or absorbent materials to clean spills outside of the printer such as sawdust, clay, diatomaceous earth, or activated charcoal and placed into containers for transfer to an approved waste disposal site.  

 Caution: Never put sawdust, clay, diatomaceous earth, or activated charcoal inside the printer, doing so will damage the printer. 

 If spilled material is hot (liquid), wait until it cools before wiping up. Use of heat above 65° (149°F) may prove helpful in removing spilled support material from carpet. After wiping up the spill, wipe surface with denatured or isopropyl alcohol and clean thoroughly with soap and water.

Some cleaning solvents are highly flammable such as denatured alcohol and isopropyl alcohol. Before using solvents to clean and remove uncured part material, be sure read and follow the solvent supplier safety precautions and recommended usage.

Flammability Hazards

Though the U.S. Department of Transportation does not consider VisiJet materials a "flammability hazard," they do classify them "combustible" based on flash points. Material containers may rupture when exposed to extreme heat. Use National Fire Protection Association Class B extinguishers such as carbon dioxide, dry chemical, or foam.

The three dimensional solid parts consist of two materials (support material and part material). The support material is a wax based material providing adhesion to print platform, as well as, providing material used to produce supports required to build the your part.

The part material is a wax material. After a layer of material is deposited on the build plate, the part is immediately solidified by cooling of the molten wax. When the build is complete, the part (consisting of the two materials) is adhered to the print platform by means of the support material).

The material delivery module consist of four material cartridge holders; the two left side holders are for the support material (white) cartridges. The right side of the module are for two part material (grey) cartridges. Once materials are heated, they are fed to the printhead. Material waste is generated by two processes; cleaning the printhead array plate and planarization. The cleaning process involves purging jets and wiping the printhead array plate. The planarizer removes excess material during the print process. The combined waste materials are then periodically emptied into the waste bag. The printhead cleaning process is invoked automatically prior to starting a build.
. 

After the build is complete, the print platform and the part are then removed from the printer. A secondary operation, known as post processing, is required to provide a finished/cleaned part. Refer to your Post Processing Guide for more information.

POWER THE PRINTER

1. If the printer is not already on, turn printer on by flipping the power switch on the back of the printer. UI may take up to a minute or so to come on. After about a minute the 3D Systems logo should appear and then the Status Screen will appear.
2. If printer has been shut down and is starting from a cold state, wait 2 hours for printer to warm up before starting a build job. UI display will show Warming on the Status screen under Printer State (1).

NOTE: Build files can be submitted but will not start printing until printer is warm and ready.

Installing New Material Cartridge

NOTE: Cartridges cannot be installed into a cold printer. The printer must be warm before drawer will open and cartridges can be installed.

To place a material cartridge into the MDM, perform the following steps:

1. Obtain a new material cartridge ensuring that it is the same material as currently installed in the MDM.

2. If drawer is not already open, push to unlock drawer.
3. Pull open the MDM drawer.

	NOTE: The steps to install a support cartridge are the same as installing a part cartridge.
	NOTE: To install cartridges into the MDM drawer properly ensure that the small cap be installed away from the user.
	NOTE: It is important to verify the cartridges have been audibly clicked into place, have material in them, and the cartridge caps properly ventilated; otherwise the printer may not be able to pull material from the bottles, potentially resulting in the following fault codes:
	93-134 thru 137

4. Place cartridge in slot and push down until you hear it click in place.

5. Vent each cartridge by loosening the material cap (A) by a 1/2 turn counterclockwise.

6. Close the MDM drawer (B), by pushing in the dimple at the top until it’s latched securely.

7. Check the material level under the Materials tab (C) on the UI to ensure cartridge is seated properly into MDM and ready to print.

REMOVING MATERIAL CARTRIDGES

When a material cartridge is empty and needs to be replaced, or if a partially filled container needs to be replaced with a full container, perform the following procedure.

NOTE: It is important to verify the type of material currently in the MDM before proceeding with these steps.

NOTE: Cartridges cannot be removed from a cold printer. The printer must be warm before drawer will open and cartridges can be removed.

The MDM drawer (A) is a push/push mechanism. Push to open drawer, push to lock drawer.

1. Open the MDM drawer by pushing in at the recessed dimple.

2. Pull the MDM drawer open.
3. Turn the material cap (B) a 1/2 turn to clockwise to tighten the vent cap.

4. Press the release button (C) on the front. You will hear the cartridge release. Pull the cartridge out of the slot.

5. Dispose of the empty cartridge according to local regulations.
6. Wearing nitrile gloves and either protective sleeves or a lab coat to protect arms, use a disposable paper towel and wipe all material from the container seal assembly, if necessary you can use some isopropyl alcohol on the paper towel to wipe up the excess material.

NOTE: It is important to always wear nitrile gloves and either protective sleeves or a labcoat to protect arms when coming in contact with materials to avoid getting materials on skin. Contact with skin may cause an allergic reaction.

WASTE BAG REMOVAL AND INSTALLATION

NOTE: Even though  the waste bag may not appear full when the user is notified to change it, it is highly recommended to replace the waste bag when prompted to avoid unnecessary overflow and mess. When waste bag has been changed ensure you confirm the level has been reset to zero.

1. Verify that the printer is in READY.
2. Select Materials tab.

ProJet® MJP 2500W	ProJet® MJP 2500 IC

3. Select  next to the Waste Bag status bar.
4. Wearing protective Nitrile gloves, open the MDM drawer.
5. Remove the waste bag and dispose of bag according to local regulations.
6. Inspect the waste bin for any remaining waste. If necessary, wipe out any waste that exists with a lint free cloth and isopropyl alcohol.

NOTE: If the waste bag is stuck to the liner when you attempt to remove it, replace the entire liner and bag to prevent the bag from tearing and causing material to leak into the receptacle. Waste bags can be ordered using part number 310248-00. With each order you will receive 50 bags.

7. Confirm on the printer UI when you have completed replacing the waste bag.

The Waste Bag routine can also be accessed from the Operator Maintenance window:

8. Unfold cardboard insert.

9. Carefully place insert inside of plastic waste bag.  Do not push down insert fully to the bottom of bag as this may cause the waste bag to tear.

Note: Do not push down insert fully to bottom of bag as this may cause waste bag to tear.

10. Check to make sure the waste bag counter has been reset to 0%.
11. Close MDM
