This guy just built a working 3D printed semi-auto gun!
The man, who is a carpenter in West Virginia using the pseudonym Derwood, but remains otherwise nameless, claims that his working 3D printed semi-auto gun was built with 95 percent 3D printed parts.
The device, which he calls the Shuty MP-1, appears to be a cross between a handgun and a sub-machine gun, and is chambered in 9mm Luger.
While it is not the prettiest gun in the world, apparently, it shoots quite well as you can see in the video below.
Even though Derwood claims that 95 percent of the Shuty MP-1 is 3D printed, he admits the barrel, hammer, firing pin, bolts, and springs are all metal. In the video below, you can see him assembling his working 3D printed semi-auto gun.
Derwood claims that he built the Shuty MP-1 purely for the challenge and fun involved in the endeavor. He also says that he won't be publishing the CAD files used to 3D print the various components.
What do you think of Derwood's working 3D printed semi-auto gun?
