I also like PETG over ABS, mostly because of the very low (PLA-like) VOC’s. The VOC’s emitted from ABS smell awful and actually appear to be pretty crazy in an indoor environment. I like having the printers inside and helping the kids make projects with them, and not worrying about complaints from my wife or what I might be doing to the kids’ brains.
@Jonathon_Thrumble does PETG get stringy?
I must have hit the perfect dialed in settings by accident haha.
That was my first PETG print and just a few of the finest of hairs in the through holes (they were the width of 100th of a human hair).
I couldn’t be bothered going downstairs to get my heat gun so just waved a gas lighter over them and they evaporated.
I’m thinking I better write those settings down so I don’t forget them. Bed=100°c, extruder=255°c I’ll have to check what the retraction, print speed, fan etc etc was…
Might have also got lucky with the PETG too, it was from AliExpress
Too much heat for the hotend or too slow of moves helps ABS get stringy. I can not imagine it being different for other materials. Just the amount of trouble would change is my guess.
is it safe to print indoors?
