(Gor other readers, I am not arguing the safety points with any of this stuff. There is risk with everything about this process. Period. Understanding the properties of other chemicals is super important my comments are an addendum, not an argument.)
Not too worried about the BPA as the IPA boiling point is way too low. (At my altitude, the temperature is holding at ~84C.)
The acrylates are a bit nastier, but something to think more about. I’ll need to dig into why the resin is clumping at temperature, as that is probably the acrylates doing something special.
Still, this is extremely diluted solution until the last bits and don’t evaporate all the IPA so the resin doesn’t get cooked. (Working in a reasonable temperature range does mitigate some of the nastiness.)
These companies barely release data sheets for pla filaments. I wouldn’t boil anything with resin in it in any garage for any amount of money.

Brother, I hope you’re in one of those Andromeda Strain full body suits.
