General Tips for All Materials
  1. Use orientation to minimize large cross sections areas. Orient parts per best practices and on YouTube Module 3 & 4 tips.
  2. For full platforms and parts with cross sectional areas, print quality is best in Premium mode. Or add 1-2 seconds to slow down the Interval Pause Time and the Interval Down Time in the Build Style by an extra 1-2 seconds.
  3. Large flat bottom surfaces can be improved by increasing cure depth from 10-20%, pending effects of fine features.
  4. Verify all holes, bosses, and fine features are supported properly when using auto-generated supports. If support issues occur, increase density of supports and tip ratio.
  5. For large parts, dense arrays of parts, or negative features in bottom of part, you might wish to clean the parts while still on the print platform. If this is the case, increase Minimum Support Height to 5-7 mm to make cleaning under the parts easier.
  6. May need to remove the bottom of bulk of supports (not tips) before cleaning. Allowing part to dry before removing supports allows for less scratching of part.
  7. After a curing cycle in the LC-3DPrint Box, the glass plate inside will be hot. To prevent part warping, avoid placing green parts on the glass plate when it is still hot. For best results on large or flat parts:
    1. Post-cure for 20 minutes on the build platform and allow five minutes to cool
    2. Remove part from build platform and remove supports.
    3. Cure the part on the glass for the standard amount of time listed in the chart below.

  2. To avoid chipping printed part during post processing, do not support part too close to its edges in 3D Sprint.

  3. To avoid areas of color differences on your parts, space parts well in LC-3DPrint Box to avoid parts casting shadows on each other.

Figure 4 RUBBER-BLK 10
  1. General best practices apply.
  2. Material is soft when green. You must orient it in 3D Sprint to allow for the maximum number of support locations.
  3. Tall parts (>100 mm) print best at 30 µm layer thickness.
  4. Take care when handling green parts due to their flexible nature.
  5. IPA does not dissolve this material. Propylene Carbonate must be used when cleaning printed parts.  IPA should only be used as a final rinse.
  6. Parts can be sticky until post cured.

Figure 4 EGGSHELL-AMB 10
  1. General best practices apply.
  2. When using parts to create injection molds, keep supports on the part to hold it steady during injection and current process of silicones.
  3. There are many commercial silicone and RTV materials used for eggshell molding. Use the following during post-processing with EGGSHELL-AMB 10 to improve any inhibition issues:
    1. When cleaning parts, use acetone instead of IPA, following the same cleaning instructions for IPA from the Post-Processing Guide. Follow all SDS and safety precautions when using any solvent for cleaning parts.
    2. Dry parts in an oven at 60°C (140°F) for one hour before post curing.
    3. Post-cure parts for 180 minutes.
    4. Reheat parts for one hour at 100°C (212°F).
    5. Cure injected materials at an elevated temperature, such as 60°C (140°F), for one hour if material allows.
    6. Clean parts with soapy water after post-curing. Dry parts thoroughly.
