Been a while since I’ve been on here. I recently picked up some PETG from a local supplier as an emergency, they didn’t have any 2.85mm ABS which I usually use. I’ve had it a few days now and I just can’t get it to behave, I’ve had 3 nozzle jams and a tonne of stringing. I’ve googled and read about and tested many different things; temperatures ranging from 255 to 215, fan speed from 0 - 70%, print speeds from 30mm/sec to 60mm/sec, different retraction settings, travel settings, messed around with coast and wipe in s3d, the lot. Filament measurement is absolutely bang smack on - measured and remeasured 3 times just to be sure - and flow rate down to 95% (94% starts leaving gaps between passes).
I can get smaller objects or solid, single piece objects to print perfectly but anything with travel moves over the perimiters is just covered in globs and strings and nothing I’ve done has managed to change that.
I think I’ve since decided the standard Taz 5 extruder just doesn’t like this material. I know it can be printed cleanly, the shop I bought it from were using the same type (same brand, same colour, same size) when I went in to print 4 seperate large objects at once on one of those new raise3d printers without so much as a hint of stringing, and some of the prints they showed me which they’ve made with PETG were outrageously good (so good you would have thought they were injection moulded).
What kind of objects is everyone managing to print with PETG? I’m interested to see what people are pulling off without creating such a chaotic, hideous mess.
