Result: Unusable. Same result as before but less severity. Failure.
I still think this is a curing issue. I believe there is still uncured resin inside the model causing the temperature differential which causes the model to expand which is damaging the investment.
I have a few more models in various stages of curing and I'm starting to notice a significant color change as the model cures. The initial color is a light yellowish-green and changes to a almost white color with a tinge of purple (this is noticeable on the first prints).
