We’ve seen no shortage of 3D-printed masterpieces over the last several months, but this is reportedly the first time that someone has used the technology to create a firearm. It comes from a users on the AR15 message boards, a community for gun fanatics. He used a Stratasys 3D printer to create a .22 pistol. And yes, it actually works; it can shoot bullets just like a normal gun.

In fact, the user claims to have fired more than 200 rounds out of the machine, and says it still works just fine. But he didn’t stop there. He also assembled a .223 rifle upper and attached it to the lower, again with 100% success. There are multiple resources and blueprints for guns on 3D printing websites, but this is believed to be the first documented case of someone actually creating a working model.

3D printing may still seem like a science fiction concept to the uninitiated, but to those who are willing to open their eyes, it is very apparent that it is here, it is now, and it is exploding in popularity. Everything from glasses to bikinis to coasters to artificial bones to guitars (need we continue?) has been successfully printed from a 3D printer. It’s fascinating to watch this next evolution in scientific advancement.
