Abandoned printing a few years ago, getting back into it. I have several rolls of PLA and one ABS. The PLA rolls are brittle due to being stored in the open for years. I ran them through a dryer at 50c for 12 hours with no improvement. I’ve seen suggestions online for 55c so I’m trying that right now, but I imagine they’re fucked.

Will more heat help or am I wasting my time?
