Anycubic Wash & Cure 365nm LED blocker

thingiverse

I've been successfully printing pieces that I want to be crystal-clear by working closely with SirayaTech's chemist. The secret lies in the fact that most resins come pre-tuned to cure with UV light at 405nm - check the label on the bottle for proof! Unfortunately, the Anycubic Wash & Cure machine has a mixed setup, with half its curing LEDs operating at 405nm and the other half at 365nm. Using 365nm UV with transparent resins meant for 405nm can lead to an unpleasant yellowing effect. I've solved this problem by blocking all the 365nm LEDs on my Anycubic Wash & Cure machine, which ensures that only 405nm UV LEDs are used - a move that greatly reduces yellowing of clear resins.
