First Prints (#2)

I received my Form1 about a week ago and we are getting acquainted.  Does anyone know what causes the yellowing of the transparent resin?  Is it a heat or humidity thing?  Is there anything I can do to keep it from happening?

The yellowing comes from continuing curing – direct sunlight, etc. You might try a UV-blocking transparent spray to minimize the effects.

Thanks Sam,  Would something like this work? (

Any UV spray safe for plastic should work.  I think I’ve used the gloss version of what you’ve linked and it does slow the yellowing (but not stop it.)
