My robot arm will be using the black an fluor orange colouring scheme. The stepper motors are mounted in the black parts. Those parts can get to hot for PLA (max 60°C). PETG can handle 80°C and should be easier to print then ABS. PETG has no shrinkage and no bad smell.
I will try to print all of them in PETG. But I'am having a little bit of trouble printing the support in PETG. It sticks to the print head. I'am also going to change and reprint the base because I want to add a fan inside.
