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.

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:

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.

NOTE: Contact certified reseller partner or 3D Systems Customer Support when the UI continues to report an empty cartridge even though the cartridge is non-empty and is seated properly in the MDM.  Contact your certified reseller partner first or contact 3D Systems Customer Support, whose contact information can be found here.

NOTE: Make sure you are wearing Nitrile gloves and protective clothing before performing any of the following procedures. Always protect yourself from possible exposure to materials. Always wash hands thoroughly with soap and water after handling parts and/or material. Never eat or drink without washing hands first.

3. The printer will move into position in order to allow access to the print platform. When prompted, open the door to access the print platform.
4. Lift to remove the platform.

5. Install clean print platform. Close top door. If it is placed correctly the platform will automatically lower and clamp the print platform in place.

6. A message will display (see below) asking user to confirm that the platform is clean, verify the platform is clean.

NOTE: Always be sure you are installing a room temperature print platform that is clean on both sides to avoid any printing issues. Also, confirm that the print platform is free from damage due to any drops or dings. Protruding metal on the platform may come in contact with the printhead and cause severe damage.

For each VisiJet M2 material, the "General" build styles in 3D Sprint are designed to give you accurate prints right out of the box. Please use the "General" build style 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 "Scale and Offset Wizard" in 3D Sprint to troubleshoot such issues.

Each ProJet MJP 2500 printer will vary slightly in accuracy. If you have multiple printers, you may need to set the accuracy for each one separately. To do this, click the "Printer" icon in the upper left corner, connect to a specific printer, and run the steps in this section for each printer. Additionally, you will need to run the wizard for each Material,Print Mode, and Build Style combination you use.

1. Click the "Load Reference" button to load the accuracy models that will be printed. 
2. Print the reference build on your ProJet MJP 2500, then post process the parts.
3. Click the "Printer Tools" button, then select the "Printer Settings" button. 
4. In the "Printer Settings" window, select the build style you used to print the reference build, then select the "Scale and Offset Wizard" button. 
5. Measure each part using calipers, micrometer, or height gauge, then input the measurement values to corresponding boxes in the "Scale and Offset Wizard". Each measurement is repeated 4 times. Be sure to input the values for parts labeled with X, Y, and Z before selecting the "Next" button.

NOTE: Before measuring, wipe each end of the measurement part with a paper towel to remove excess wax remaining after post processing. Also be sure to wipe clean your measurement device before measuring.

6. Once all measurements are complete, select the "Next" button.

7. You can now see the calibrated slope and offset values. If you calculate a corrected slope and offset on your own, be aware that the offset range will be limited to [ 0, -0.002 ] inches. 

8. Select "Apply", and 3D Sprint will allow you to change the name of your new "Build Style". By default, the syntax includes build material, print mode, and the date. You may add to the printer name as well if you have more than one ProJet MJP 2500 printer.

9. Be sure to press the "Set" button instead of closing the printer settings window. Pressing "Set" will not only set this new build style for your current 3D Sprint build, it will also save the build style for future use.
10. 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.
11. Remember that the Build Style is tied to the build material and print mode you are using. If you use a different print mode, build material, or printer, you will need to run this wizard again for that combination. The software will automatically create "name the new build style", but you can click the "Rename" button to rename it.

12. When you select this build style in the future, you can verify that this is the style with scale factors applied by looking at the scale and offset fields in the "Printer Settings" window.
13. Print your next build using this new build style. The accuracy of your parts should now be slightly closer to perfection.

For successful build jobs, when a user wants to switch from one part material to another without material mixing, a full Material Changeover (MCO) must be performed. A full MCO is required when switching from a rigid material to a elastomeric material or vise versa. 

	NOTE: Please ensure you have replaced the waste bag with a new empty one PRIOR to starting the Material Changeover Procedure. Also, ensure you have the required materials for the material change – two MCO Cleaner 2500 cartridges, two new part material cartridges and two support material cartridges for head maintenance cycles.
	NOTE: Full-MCO requires two support cartridges present to complete successfully.

NOTE: If MCO is not performed correctly, the color profile of the new installed material may have residual original material color.

1. Ensure printer is in Ready state. Select Tools > Material Change Wizard from the UI.

2. Select  to start the Material Change Wizard.

3. Verify you have the required material on hand to start the material changeover procedure and select CONTINUE.

Evaluation Criterion 1 of 3:  What is the total count of gaps in the part and/or support material side of the print?

Part Material Pass: If there are 10 or less gaps in the part material side of the print

Support Material Pass: If there are 5 or less gaps in the support material side of the print

If both the part and support material pass, proceed to the second evaluation.

Evaluation Criterion 2 of 3:  Are there 5 lines between the gaps in the same row of part or support material?

Fail Samples 

Pass Samples

If all gaps within a single row have 5 lines or more between them, proceed to the third evaluation.

Evaluation Criterion 3 of 3:  Are there at least 2 lines between a gap in a row above or below?

When performing this evaluation, only compare rows of part material to other rows of part material and only compare rows of support material to other rows of support material.

Do not remove any outer panels when cleaning the printer. Panels must only be removed by qualified 3D Systems Technical Support Representatives.

Remove dust from outer surfaces of printer by wiping with a clean, dry, lint-free cloth.

Remove dirt and grease from printer outer surface by spraying all-purpose cleaner on a clean cloth and gently wiping it down.

CAUTION: Use 50% IPA and 50% water with a soft cloth to clean surfaces. Do not use all-purpose cleaners containing petroleum-based polishing agents such as liquid wax.

NOTE: Before cleaning, the 3D printer system must be idle to avoid aborting a build.

Polycarbonate Top Door should be cleaned with a non-abrasive cleaning and damp cloth. Gently wipe surface using dampened cloth to remove debris.

CAUTION: Do not use cleaners such as Windex™ and paper towels to clean polycarbonate surfaces. Use 50% IPA and 50% water with a soft cloth. Using anything else will scratch the polycarbonate surface.

Any time parts are processed, it is a good practice to clean the print platform and re-insert it into the printer. Follow these steps for cleaning the platform:

1. Use a flat razor blade or putty knife to scrape any excess support material off of the platform. Be careful not to scratch the black coating on the platform.
2. Spray the platform with isopropyl alcohol (IPA) and wipe with paper towels.
3. When cleaning the print platform, always clean both sides.

NOTE: The print platform should be clean and at room temperature before installing and using it in the printer.

Remove any printed parts before cleaning the user interface. This will prevent the printer from initiating any actions if controls are accidently pressed.

Spray a water-based solvent such as Simple Green onto a lint-free soft cloth; do not wipe with a dry cloth or spray cleaner directly onto touch screen.

Gently wipe dirt and part material residue from touch screen using an ammonia-based glass cleaner on a clean, lint-free cloth.

Do Not Use:

• A dry cloth on the touch screen
• Any cleaning products that contain acetone, MEK or alcohol
• Any abrasive cleaning products
• Using these cleaning products can damage the touch screen.

The following general maintenance procedures provided must be accomplished to help maintain high part yield and to reduce the printer down time.

When changing material cartridges, material may be present in the MDM receptacle after the cartridge is removed. If a large pool of material is present (bottom is submerged and walls of the cartridge receptacle are reached), do not place a clean material cartridge into the receptacle, call your reseller/partner.

CAUTION: The MDM cartridge receptacle and material will be warm; avoid touching the sides of the holder during the cleaning process. Wear heat resistant gloves and goggles.

Cleaning the MDM Drawer

Using Isopropyl Alcohol and a lint free cloth, dampen cloth with the alcohol and clean around the cartridge receptacle.

It is necessary to keep the printer clean and free of debris by cleaning up any dust that has collected around the printhead and the surrounding areas. Depending on the printer usage, it is recommended to clean every week for light usage and every print for heavy usage.

Items needed

• Nitrile gloves
• Lint free paper towels or a damp cloth
• Isopropyl alcohol or similar non-abrasive cleaner
• Vacuum or compressed air hose

Items to clean

• Beauty plate
• Inside and outside of Planarizer cover
• Outside of printer

Warning: Do not clean the underside of the printhead (Jet stack). Doing so will cause severe damage.

Shrink Compensation for ProJet^® VisiJet^® Materials

Material shrinkage occurs in thermosets as they transition from liquid state to solid state during the curing process.

The 3DSPRINT Client Software has features that allow the user to compensate for the natural shrinkage of the material in order to fine tune the accuracy of a part.

These shrink compensation values serve as general guidelines to setting shrink compensation. Part building and cleaning in a controlled process will best determine the optimal shrink compensation values for a particular geometry.

ProJet® MJP 2500 Default Shrink Compensation Values for all materials are as follows. New default values MAY be rolled out without software update notification.

* Replaces former VisiJet® materials (RWT, RCL and RBK).

Identify the exact X and Y dimensions of the part using a CAD program.

• Most CAD programs and simple .stl file viewers will provide a way to view a part with its dimensions.
• Make note of the actual X and Y dimensions as XCAD and YCAD.

Build and clean the part and take measurements of the finished part.

• It is recommended to measure along the critical dimensions of the geometry, take measurements in multiple areas and take an average of the values.
• Measurements can be made using calipers or more advanced metrology methods.
• Make note of the X and Y dimensions of the printed part and mark them as XPART and YPART.

NOTE: If the measurement of the finished part is different from the measurement of the CAD model, fine tune the accuracy using scaling factors.

Determine the Scaling Factor to use for the next build

Use the following formula to calculate the scaling percentage to be used for fine tuning the build:

XCAD = XCAD x (1 + X Scaling Factor) x (XPART / (divided by) XCAD)

YCAD = YCAD x (1 + Y Scaling Factor) x (YPART / YCAD)

Therefore,

X Scaling Factor = (1+ (XCAD - XPART) / XPART) x 100 (answer will be a percentage)

Y Scaling Factor = (1+ (YCAD - YPART) / YPART) x 100 (answer will be a percentage)

Example:

X measurement of CAD model = 3.000"

Y measurement of CAD model = 5.000"

X measurement of printed part = 2.998"

Y measurement of printed part = 4.989"

X Scaling Factor = (1+ (3.000 - 2.998) / 2.998) x 100 = 0.067%

Y Scaling Factor = (1+ (5.00 - 4.989) / 4.989) x 100 = 0.22%

Applying Shrink Compensation Values

There are two ways (Methods A and B) to select or enter new custom Shrink Compensation for the job.

Method A

Enter standard Shrink Compensation Values for the material or entire print job.

1. Open 3D SPRINT™ Client Software and select Print > Printer Tools > Printer Setting.

2. Select the Add Button.

4. Give this new Shrink Compensation a name, enter the new values, click SET.

5. Now the printer is defaulted to the new set of shrink compensation values. The bottom right corner information window is providing the new maximum printable size for XYZ accordingly per shrink compensation. You can now load jobs and print to the printer using these Shrink Compensation values.

Method B

Select Shrink Compensation Values for this material.

1. Open 3DSPRINT client software and select the Printer.
2. Select the printer (use cursor to show printer  information) you wish to print the job with and then click Next.

3. Select material for the job, click Next.

4. Select Print Mode, and then click Next.

5. Pick your Build Style with Shrink Compensation values entered in Method A and click Set.

6. Now the printer is set to print with the selected shrink compensation values. The information window is showing maximum printable size for XYZ accordingly per Shrink Compensation. You can now load jobs and print to this printer with these particular set of Shrink Compensation values.
7. Now this job is ready to print with the chosen shrink compensation values for the parts. You can now add the job to the Print Queue for printing.

Print your part(s) with scaling factors and confirm by measuring. Process may need to be repeated depending on the various geometries of parts.

The ProJet^® MJP 2500 Series uses codes to identify various fault or status conditions with the printer:

• Status about the device, for example, cartridges are low on material
• User-clearable faults, by the user performing cleaning procedures
• Printer-clearable faults, where the printer is automatically attempting recovery
• Service required faults, which can only be resolved by a certified partner

Check the Printer Status envelope for current printer conditions.

Codes listed below describe user-clearable and printer-clearable faults:

Machine Powered On, UI Blank/Black

Issue: The printer has power, fans are on, umbilical thermals are working, LED lights can be observed on the circuit boards, but the UI is blank/black and appears dead.

Probable Causes: The UI is not powered, software issue, UI SD card missing/not inserted, cable issue.

When the UI receives power, it will flash on and then appear to go blank, but if it is powered, there will be a small amount of visible light in/around the display.

Troubleshooting Steps

Power cycle the printer, if the UI doesn't come up Contact a Certified Partner for service.
