I don't know of any... "non-victimless" crimes committed with 3D printed firearms, but this legislation may be related to the guy in Port Jervis who was caught "manufacturing" via 3D printer this summer. I don't know more details than what's in this article. Though the crime here is manufacturing, the guy must have been distributing them for this narcotics task force to find him.
