Dry the Build Parts

For information on the different methods for drying printed parts, please see the section Air-Drying Parts. Dry printed parts until you see no more liquid on their surfaces. For any drying method, please use the following guidelines:

  1. Always dry printed parts over a tub, lab paper towel, or absorbent cloth. Do NOT dry the part over a sink or tub that drains to normal wastewater.
  2. Discard any disposable towels used in the drying process according to all local, state and federal regulations. These towels have been in contact with uncured resin and solvents, and must be treated as such.
  3. On a regular basis, have a professional cleaning service wash any absorbent cloths used in the drying process.
  4. If you dry the part over a tub, periodically empty/clean it, discarding its contents according to all local, state, and federal regulations. The tub has been in contact with uncured resin and solvents and must be treated as such.
  5. If using an air compressor in the same room (as opposed to shop air), wear ear protection when it is in use.
  6. Always wear 100% nitrile gloves and safety glasses when handling partially cured printed parts. When drying with a high-pressure method, uncured resin or solvent may splash.
  7. If you come into contact with uncured resin during part drying or at any time, wash the affected area with soap and COLD water. Any clothes contaminated with uncured resin or solvent must be dry cleaned promptly.
  8. There might be remnants of supporting architecture left on your part(s). You can remove these supports by hand in the majority of cases. If you experience any issues removing supports, please see Troubleshooting item PCI4.

Drying Time Quick Reference

No matter which method you use to dry your part, you must ensure it is completely dry before proceeding to the post-curing step. The chart below serves as a quick reference for suggested air-drying times. If you dry the part with compressed air before letting it out to air dry, you will significantly cut down the time needed for air drying.

CAUTION: Using compressed air is not a replacement for air drying. After drying with compressed air, you must still leave the part out for at least 30 minutes to completely dry.
