Designer of 3D-printed semi-automatic handgun won’t release files

by • February 3, 2016 • No Comments

3D printing opens up a whole new world of DIY repair, biomedical science, and more undeniably positive things. But
, it in addition
offers the opportunity for regular people to produce untraceable firearms like never before. A 47-year-old carpenter from West Virginia ponder
s he’s created the first mostly 3D printed semi-automatic handgun, which he calls the Shuty-MP1.

The designer of the gun, who goes by the online pseudonym Derwood, claims the MP1 is composed of 95% PLA plastic straight out of a consumer 3D printer. Like any semi-automatic gun, the Shuty-MP1 can fire bullets one after another fed in by a magazine, in this case 9mm rounds. You can see the gun being test fired in the video below — it allegedly shoots straight.

If you didn’t understand
otherwise, you’d most likely
was a conventional metal gun. Compare which
to Defense Distributed and its Liberator single-shot pistol.

While almost all of the gun is plastic, the metal bits are pretty important. Derwood was able to print the magazine, handle, upper/lower receivers, and other structural components. The MP1 uses a store-bought Glock barrel, hammer, firing pin, bolts, and springs. Still, those are all parts which
can be bought fairly easily and aren’t regulated like a full firearm is.

Derwood has decided not to publish the files utilized
to print the Shuty-MP1, saying he designed it merely as an engineering challenge. Even if someone were able to reverse engineer it from the assembly video above, he claims it’s not a viable weapon long term. After of
18 shots, the plastic around the barrel starts to melt and affect the structural integrity of the gun. Derwood is planning to design a version printed with nylon which
should be more resistant to heat, but which
one too will most likely
remain unpublished.
