I’m pretty new to PETG, and have been really struggling with it compared to PLA. My latest print of this part is dimensionally accurate, but I need it to be air tight. It is very much not at the moment.
I have a Flashforge Adventurer 3, so the hot end and nozzle are one interchangeable unit. My higher temp nozzle is 0.6mm. My 0.3mm is only capable of 240. My last print was 0.2mm layers, with the 0.6mm nozzle at 245C. I used 15% overlap on my walls, and in order to keep my nice dimensions I had my cooling fan on.
Anybody have any advice on how to improve the seal? I’m tempted to try more overlap, with random start locations per layer. Do you think if I run it hotter I can get the layers a little thinner? Any advice would be appreciated.
Yeah, I will definitely try smaller layer height. The wall thickness is only about 4 or 5 perimeters wide at the thickest point, though. So, I can’t really increase that I’m afraid.
