3D printing of
actual machine parts.
So you're thinking of prototypes when you’re thinking of 3D printing? Well, we can't blame you. That is what it has been used for, for over 30 years. But: sit down and hold on tight: you can now use 3D printing in the world of grownups, as a valid production technique.
Right now - day after day - we produce thousands of enclosures, guides, grippers, brackets, gears, clamps, spacers, molds, holders, pumps and valves. Genuine machine parts. Anyways, you get the point.
