Comment on What is the best (liquid) glue for gluing PLA prints together?

I set this up a good 25min ago, let’s see what happens. It’s polymaker polyterra PLA, 3 walls, 15% gyroid infill and some fuzzy skin with default parameters from orca slicer.
So far all I have is very slight color leeching out, but nothing has dissolved so far. I’ll let it run for a few days and keep you updated.
This is Prusament PLA dissolving in acetone in seconds:

I’ll come back to it in 30 minutes and it’ll be a messy soggy half-dissolved thing. And it’ll be fully gone within the hour.

Interesting if that happens, but that seems to be caused by additives used by prusa in their filaments then, because from a chemical standpoint the crystalline structure of PLA is simply not dissolvable by acetone. It can cause swelling and delamination of layers, but not actually dissolve it (without additives that mess with the polymer chains)
