Interesting Updates on Temp, UV exposure, and water found after my last post: Formlabs has more information posted on “post-curing”: They recommend curing at 60C in 405 nm UV for 15/30/60 minutes for clear/opaque/fancier resins. https://support.formlabs.com/s/article/Form-Cure-Time-and-Temperature-Settings?language=en_US
Now, our really first successful print was cured far below normal room temp, 4-8 C, but they want 60C!!! So, I have no idea what the sensitivity to Temp or importance of that is.
And then there’s water: The user groups seem to like water, sometimes warm water, sometimes after the first wash, and sometimes they like UV curing in water.
Testing IPA, Yellow Magic and RTX with castable resin and in between UV curing with LED array doesn't seem to do anything.
That all segues into the discussion of replacing IPA.
People want to find alternatives to IPA (flammable and harder to find now in EU). I would be careful about the comments on replacing IPA. I have read of tests of part of these ideas, I’ve seen people have the first solution last longer if it is something other than IPA, but I have NOT seen a straight comparison between IPA and “Yellow Magic” or other solutions. Just search the user forums for “IPA replacement” if you are interested in pursuing this.
I’m going to see how far I can get with warm water, seems pretty harmless, and UV light strips for when I can’t get ideal sunlight.
