Printed Part Quality

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. To prevent this, be sure to fill material back up to the minimum level specified in this guide before building.
2. Tension latch down and resting on the springs but not engaged, membrane not tensioned. Check that latch is fully down.
3. 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 print material.
   
   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 Cables to determine if you can clean your lens, or if the material 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 material spills, contact your reseller immediately.

4. The part orientation on the print platform can contribute to delamination. Please see the Figure 4 Best Practices to find out the best way to orient your part.
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 Tray.

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 print material.
   
   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 Cables to determine if you can clean your lens, or if the material 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 material spills, contact your reseller 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.
   2. This is not required if you completed Method A successfully. For Method B, empty the resin tray and clean the partially cured material out. This method can be particularly useful if cured material is fused to the resin-tray film, rather than just floating in the material.
      
      1. Discard the material in the resin tray according to all government regulations.
         

      2. Wearing 100% nitrile gloves, hold the resin mixer at the edge of the cured material, while simultaneously gently pushing the cured material 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 Tray.

Any one of the following could be the cause:

1. Print material was not mixed in the bottle before pouring - Be sure to mix the material before pouring, according to the section Mixing, Stirring, and Curing Chart.
2. Material was not stirred in the resin tray before printing - Be sure to stir the material before printing, according to the section Mixing, Stirring, and Curing Chart.
3. You may have poured the wrong material - Ensure that the material you pour in the resin tray is from the same bottle you scanned.
4. You may have over-cured or under-cured the part - Ensure the part is cured as recommended in the Material Stirring and Curing Chart.
5. You may not have cleaned the resin tray well enough before changing from one pigmented material to another.

This could be caused by:

1. Dirty projector lens - Clean the lens according to the section Inspect Projector Lens and Cables.
2. Tension latch down and resting on the springs but not engaged, membrane not tensioned. Check that latch is fully down.
3. Dirty catch-tray glass - Clean the glass according to the section Clean/Replace the Catch Tray.
4. Debris on the print platform - partially cured material 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.

The optimal operating temperature of the printer is between 18°C-28°C (64°F-82°F). If you attempt to start a print job while the printer temperature is outside these limits, you will see the screen below. Adjust your facility's temperature to be within this acceptable range and, once this temperature has been reached, the message will disappear and you can continue printing. Tap the Cancel button to go back to the Pending Job screen.

Print does not start.

1. Make sure to follow UI prompts.
2. If still experiencing issues, contact your reseller.

Part did not build.

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 print material used in the print.
3. Ensure that Print Platform is seated correctly on elevator arms.

Part does not adhere to supports.

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

Pitting/Chalkiness

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).

Line Defects

1. Check for debris in print material. 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
