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.

  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.

Pre-mix resin on LC-3DMixer before pouring

New bottle - 1 hr.

After 1st use - 10 min.

(see Note 1)


Mix resin in resin tray before printing

30 sec.

Post-Processing Guide

Cleaning Charts

30 min. (see Note 2)

NOTE 1: Considerations for resin that has been sitting, unused, for over 1 month - If you have a resin bottle like this, simply treat it like a new bottle and mix it for the time specified in the "Brand-new bottle" column in the above chart.

NOTE 2: Ensure that you place the build in your UV curing oven in the same orientation it was printed in, as if the bottom of the oven is the print platform.
