@olivero said in PETG In elevated heat application for commercial use:
rinted a test peg out of ABS, PLA and now PETG as the material arrived and my main concern was the temperature, the water temperature in the machine gets upwards of 170-180*F so when I got the first Peg I put it through the machine and it actually survived really well, no flex or softening and no surface deform or layer split, it went through a
Welcome to the world of 3D printing, glad you are here!
I am glad to hear the PETG worked for you to start out! I know it has a glass transition temperature of 80C ( about 176F) which it will start to get soft. That is kinda surprising but great news!
It is a bit hard to say how to resolve the cracking you are seeing.
PETG itself can be slightly flexible in some cases depending on your infil or walls.
If parts are cracking like that but now always, it might be the luck of the draw there.
What kind of settings are you using for infill and your walls?
Given the size of your part, I would say increase the walls vs infill since there wouldnt be much a benefit for strength.
