Clean Printed Parts

The PWA 2000 Parts Washing Apparatus is the recommended washing unit for the Envision One cDLM™. To get the information on how to clean a printed model with PWA 2000, see Hardware Operations.

Clean Parts without PWA 2000

Tip: The first container in which the parts are placed in is referred to as the “dirty bath” because this solution will become muddy fairly quickly. The second bath is the “clean bath.” Each bath must be filled with enough 99% IPA to submerge the parts fully.

To clean the parts without the PWA 2000:

  1. Fill both containers with 99% IPA.

  2. Submerge the parts in the first bath of 99% IPA for no longer than 60 seconds.

  3. Use a brush while the parts is submerged to help clean out smaller features of uncured material. Parts may also be swished or gently stirred.

  4. Remove the parts and spray with compressed air until completely dry.

  5. Examine each part for variations in the surface quality. Glossy sections will need to be focused on during the second rinse cycle.

  6. Place parts into the second, or clean, bath of 99% IPA.

  7. Repeat the process by submerging parts for 60 seconds, then blowing each part dry.

  8. Repeat this step as needed until each part has a uniform matte finish.

  9. Dry models quickly with compressed air as extended time exposed to IPA can cause micro-cracks.
