Question by Kitshmoff: Is it currently attainable to 3D print all the parts needed for a 3D printer?
Is it even achievable to print a servo motor?

Answer by Mr. Wizard
Not actually, no. We’re not there however. Given that a servo motor is made of all kinds of other materials like aluminum, iron and copper, there’s no way for a 3D pritner to print that out of nothing at all. They would require machines just for those phases of the method, nevertheless if you happen to be seeking to print a housing for the servo or a gearbox (just the gears), that is achievable!

**EDIT: @Tony — For Residence use. I know individuals who can till 3D objects as well out of aluminum core but those machines are so big, just a single would take up an complete 1-port vehicle garage, oh and they’re a total fortune too.
