I dried my filament, and it printed a lot better (lemmy.world)

If only there was some way I could have known to try this sooner! /s

Story: I wanted to try printing with petg, since I've read how much easier it is. But with a new roll I just had a really hard time. Lots of stringing, poor adhesion, and it just seemed like no amount of my usual fiddling would really make it better.

Somewhere I read that even new filament can benefit from drying, because maybe it wasn't stored in the best way, or maybe it's older than you think. I also read about putting the roll on the print bed, heating it up and covering it for a long time, since I don't have a filament dryer. I did that for about half a day, and then sealed the roll in a ziptop bag with a silica packet because I needed a break from it. A week later and, it seems much better!?

Either the drying, the break, or something else seems to have helped a lot! Happy printing everyone.

You're starting to make me think that my own PETG issues may be due to more than my laziness about fine-tuning after all. Time to break out the dryer (which I've previously only used with PVB, another one of those highly hygroscopic materials).

Good luck to you! Let us know if it works out. (If not, just keep that to yourself!)

Heh. Don't worry—if it doesn't help, there are plenty of excuses available. I'm not going to bother doing anything with the spool I've currently got on the printer, since I'm not sure there's enough of it left to print even a calibration cube. I'll test the next spool fresh out of the package, and then after drying it for a few hours, and see whether it makes a difference. If not, it just means that the supplier I buy from actually is as careful in producing and storing their house brand as their marketing claims, and I left the old spool out for too long.
