Figure 4 Print Material Quick Reference

1. For best results, orient part to try and maintain uniform wall thickness.

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. Use Standard Thick mode for thick parts or densely packed print platform. Thick part for example is 20x20x10.

4. Use orientation to minimize large cross sections areas. Orient parts per best practices and on YouTube Module 3 & 4 tips.

5. Large flat bottom surfaces can be improved by increasing cure depth from 10-20%, pending effects of fine features.

6. 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.

7. Ensure parts are not supported on a line of supports. Best results have three supports similar to a tripod preventing the part from moving side to side during the print.

8. 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.

9. 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.

10. 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.

1. General best practices apply.
2. When printing thick parts or very dense platforms, use Premium Plus for best results. Note mode will be ~2x slower but can provide very good part quality.

2. Place parts a minimum of 8 mm apart to improve material flow and adhesion.
3. If adhesion issues occur, raise the Base Layer Curing Time to 100 seconds. It may also be necessary to change Base Truss Infill Type to 'Solid' rather than 'Connected Solid'.
4. If printing flat surfaces, reduce the Interval Distance to 3-5 mm to improve pillowing effect. Adding some supports will also improve the part.
5. When printing thick parts or very dense platforms, use Premium Plus for best results. Note - mode will be ~2x slower but can provide very good part quality.

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.

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.

1. General Best Practices apply.
2. Due to the delicate geometry of jewelry, it is a best practice to use the Modify tab to Add/Remove supports for optimal outcome.
3. Use the cure depth adjustment under the Advanced section of the Build Style window to resolve fine or negative features when necessary. Adjustments should be within 10-20 µm increments.
4. IPA already dirty with Jewel Master GRY resin cleans slightly better than using only fresh IPA.  Using a two-step dirty IPA/clean IPA cleaning process works best.
5. Remove support tips before part is completely dry to avoid damaging the part.
6. Post cure parts before sanding support nibs flush.  Parts are weaker than supports prior to post curing. After post curing, parts and supports have equal strength and sanding gives the desired result.

1. Manually check support locations in 3D Sprint before printing.

2. In thicker cross sections for large rings or non-ring geometries, go up in cure depth to avoid delamination between layers. Go up in 10 µm increments to prevent over curing features.

3. 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.

4. If positive features have poor resolution, the Border Thickness parameter in the build style could be increased up to 20%. It is not suggested to go higher, or negative features might get closed or too small.

5. If detail is blurry, verify proper cleaning method. Ensure cleaning solvents are not saturated and parts are allowed to dry before post curing.

6. If detailing is still blurred, lower cure depth in 10 µm increments.

7. If detail remains an issue, or accuracy is hard to achieve, run the accuracy wizard for this build style.

8. Make sure all IPA has evaporated off after part cleaning, and allow for parts to dry completely. If surface finish is still shiny (not matte) after cleaning, not all print material has been removed and it will show up in the casting. Repeat cleaning and drying until parts do not have any excess material.
