Learn more about basic Form 2 finishing steps; after washing printed parts, add post-curing to the printing process to stabilize the part's mechanical properties.
To automate the washing process, Form Wash agitates the alcohol bath and removes parts from the bath after a set time. Form Cure provides the necessary light and heat for resins that require post-curing.
Before finishing the first part, reference the Form 2 Finish Kit Setup information to ensure the Finish Kit is ready for use. The steps below begin after uploading and completing a print. Follow these guidelines for washing parts, and check whether there are special recommendations for washing or curing each material.
1. Remove the build platform
Always remove the build platform before removing the resin tank to avoid dripping resin onto the optical window. Close the cover immediately after removing the platform to prevent ambient light from curing resin in the tank.
2. Put the build platform on the jig
3. Use the removal tool to remove each part
To release the part(s) from the build platform, slide the removal tool under the angled edge of the base and twist, or squeeze the flush cutters under a release tab and lift.
The tools that are used to remove parts will scratch the metal surface of the build platform. Scratches are normal and improve part adherence to the build platform during the initial layers of printing.
Wash Time Requirements
The combined agitation and soaking time varies depending on the resin type, the alcohol concentration, and the system or washing method.
With Form Wash, wash the average model for the default programmed time, which is 10 minutes. With the Finish Kit, agitate the parts periodically, and soak parts printed with Standard Resin in alcohol for 20 total minutes. Other resins require different amounts of time. For smaller parts, reduce the soak time accordingly.
For more information, check for all materials’ recommended wash times. Increase the Form Wash time recommendations when using the Finish Kit or other manual washing workflows.
4. Agitate part in IPA
Open the first rinse bucket and place the part(s) in the alcohol bath. Use the rinse basket to shake the part(s) for 30 seconds. Agitation removes liquid resin from the printed parts’ exterior surface.
5. Soak parts in IPA
Close the rinse bucket's lid and let the part(s) soak for approximately half the total recommended time.
6. Repeat with a second rinse
Move the part(s) to the second rinse bucket, then repeat Steps 4 and 5 to agitate and soak the part(s) for the remaining time.
After each print, use a disposable cloth or towel to clean excess resin from the build platform and return it to the Form 2. Leaving a wet build platform on the Finish Kit makes it very hard to clean later.
7. Post-cure, as needed
Some resin types require post-curing, and the recommended time and temperature settings vary for each material. Post-curing is optional for most use cases for Formlabs Standard Resins, which include Clear, White, Grey, and Black.
8. Remove the supports
Use the flush cutters that come in your Finish Kit to carefully cut the supports attached to the part(s). Supports can also be removed before post-curing, but parts may warp under exposure to light and heat without structural support.
