Printed Part Quality

This can be caused by:

1. Not enough material in the resin tray. Ensure that the resin tray's auto-fill is filling up the tray to the appropriate level. This is around the MAX level on the tray by default, or another predetermined height set by your 3D Systems Service technician.
   
   1. Ensure there is no resin on the resin-level sensor that could be blocking it's path. Clean the sensor by spraying IPA onto a lint-free cloth and gently wiping it down.
      
   2. If the Controller/Printer asks for a new resin cartridge during printing, be sure to replace the cartridge as soon as possible.
2. Cold material. Be sure the room where you store your resin is kept at 5°C-30°C (41°F-86°F). And be sure any rooms with Modular printers are kept between 18-28°C (64.4-82.4°F).

If you have taken both of these steps and still have issues printing supports, please contact 3D Systems Service.

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

This can be caused by:

1. Not enough material in the resin tray. See PPQ1.1, above.

2. Cured material or other debris caught in between layers. Run a cleaning print before your next print job.

3. The part orientation on the print platform can contribute to delamination. Please see Figure 4 Modular Best Practices 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. Remove the resin tray and clean it, as in the section Clean Resin Trays. Also, see PPQ4.3 below.
   2. Follow the guidelines in the section Clean/Replace the Catch Trays to determine if your catch tray needs to be cleaned or replaced.
   3. Follow the guidelines in the section Clean Projector Lens 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 3D Systems Service immediately.

5. Resin-tray film scratched, dented, hazy/dirty- particularly in the failed area of the build. If scratched or dented, you must replace the tray. If hazy/dirty, clean the tray as in the section Clean Resin Trays.

This can be caused by:

1. Not enough material in the resin tray. See PPQ1.1, above.
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. Remove the resin tray and clean it, as in the section Clean Resin Trays.
   2. Follow the guidelines in the section Clean/Replace the Catch Trays to determine if your catch tray needs to be cleaned or replaced.
   3. Follow the guidelines in the section Clean Projector Lens 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 3D Systems Service immediately.

3. Cured material fused to the resin-tray membrane during a previous build, or bits of cured material were floating in the resin tray during a previous build. If this is the case, choose between either method A or B below to clean the resin tray:
   
   1. This is not required if you completed Method B successfully. For Method A, perform the procedure in the section Running a Resin Tray Cleaning After a Failed Build.
   2. This is not required if you completed Method A successfully. For Method B, empty the resin tray and clean the partially cured resin out.
      
      1. Discard the resin in the resin tray according to all government regulations.
         

      2. Wearing 100% nitrile gloves, hold the resin mixer at the edge of the cured resin, while simultaneously gently pushing the cured resin from underneath the film. Use the resin mixer to gently scrape underneath the cured part to remove it.
         

         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 Trays.

Any one of the following could be the cause:

1. Resin was not mixed sufficiently before inserting cartridge into machine. Ensure you follow the premixing instructions in the section Premix Resin Cartridge Before Installation.
2. Resin was not stirred in the resin tray before printing. Be sure to stir the resin in the tray before printing according to the section Premix Resin Cartridge Before Installation.
3. You may have failed to sufficiently complete a Material Changeover Procedure. If you performed an MCO without properly switching out all resin-related components, another resin type may have mixed with your current resin.
4. You may have over-cured or under-cured the part. Ensure the part is cured as recommended in the Resin Curing Chart.
5. You may not have cleaned the resin tray well enough before changing from one pigmented resin to another. See the section Clean Resin Trays.
6. You may have used a resin that is not compatible with that resin tray, due to resin you have run in it before. See the section Resin Tray Material Cross-Usage.

This could be caused by:

1. Dirty projector lens - Clean the lens according to the section Clean Projector Lens.
2. Tension arms are not fully engaged. See item HW8 in the Hardware Issues section.
3. Dirty catch-tray glass - Clean the catch tray according to the section Clean/Replace the Catch Trays.
4. 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.

1. Make sure to follow UI prompts.
2. If still experiencing issues, contact 3D Systems Service.

1. Ensure nothing is blocking the path of the projector's radiation to the bottom of the resin tray.
2. Ensure the build style used in 3D Sprint matches resin used in the print.
3. Ensure that Print Platform is seated correctly on elevator arms.

1. Wrong support style - Please see 3D Sprint Best Practices.
2. Not enough supports - Please see 3D Sprint Best Practices.

Ensure part is cleaned and dried correctly before post-curing:  See Part-Cleaning Procedure.

1. Do not leave part in alcohol solvent longer than recommended. See Part-Cleaning Procedure.
2. Replace alcohol solution if saturated.
3. Spot clean hard to reach areas (engraving, small holes).

1. Check for debris in resin. (if there is debris, run a resin-tray cleaning).
2. Check part orientation guide. Please see 3D Sprint Best Practices.
3. Check support guide. Please see 3D Sprint Best Practices.
