I understand the intent, but feel that there are so many other loopholes that put much worse weapons on the street than a printer. Besides, my prints can barely sustain normal use, much less a bullet being fired from them. I would think that this is more of a risk to the person holding the gun than who it’s pointing at.
Pretty soon they would have to band backyard foundries, aluminum cans, molding sand, metal files, and drill bits!
Why them flat bastards!
