This 3D printed metal gun from Solid Concepts is a copy of the revered 1911 semi-auto pistol and made so gunsmiths can get hard to obtain parts. It is completely legal and requires high end 3D printing capabilities to create.

“We’re proving this is possible, the technology is at a place now where we can manufacture a gun with 3D Metal Printing,” wrote Kent Firestone, Vice President of Additive Manufacturing at Solid Concepts. “Now, if a qualifying customer needs a unique gun part in five days, we can deliver.”
Most important, in fact, is that this is a true first.
“As far as we know this is the world’s first 3d-printed metal gun,” said McGowan.
