I do a lot of 3D printing (repairing stuff at home).
But these are old projects.
I do not own a 3D printer, but send the 3D design to a print shop. Bender the grey one was in printed with plaster. Because you can print in color then, but I for got to include the text color image, so it printed grey. The object was so fragile (legs, arms), that it broke within one day.
Don’t design things thin and printed in plaster …
