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?
Edit: another 10 hours at 55 did nothing, I’m abandoning the spool and trying the ABS at 65 for a full day. It wasn’t brittle to start so I’ll have to test print to know if it worked, but I’ll post an update here for posterity.
PLA has a shelf life, it does degrade a little especially if in a room that had sunlight. Over 3-4 years old it may not ever be usable.
You may need a very long dry time (multiple days) due to the spool likely being wet completely throughout.
Yeah that makes sense. Do you think the ABS would be more salvageable?
The ABS is more likely to be usable after drying.
