When you finished post-processing a print, especially Clear or White resin, you may see some yellowing in the print. This can be the result of:
1. Too long of post curing time
2. The UV curing LED you have emits 365/385nm UV light which yellows print much quicker
3. There uncured resins that have been repeatedly left in vat and receive enough of incidental UV light from LCD panel that it starts to yellow
4. Too long of an exposure time
While it is often best to address the root case, you still have a way to reduce yellowing in your print: heat and time.
Print's yellow will fade over time, normally over a week to two without special condition. You can speed up the process by heating the print up. For Fast, 50C for 15 minutes usually yield visible results. We recommend air heat not water heat treatment as print may absorb water.

This method only works with Simple, Fast, and Craft, not Blu Clear. This method is not limited to printing time.

Would this technique work for Blu Clear and Simple Clear if they’ve yellowed a bit?
