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.
I had the same experience…someone on the BK Discord shared this link, which I found pretty interesting https://fillamentum.com/pages/drying-filaments-before-processing/
Key take-away: cooling the filament after drying needs to be done in a controlled environment, i.e. put it in a zip lock bag with desiccant immediately after its taken out of the heat.
I have used my oven on the lowest temp but it really stinks up the house. I just realized that my food dehydrator basically does the same thing…worked out awesome
