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.
99% of the what I’ve seen is more deadly to the user than to anyone on the receiving end. You’d really be better off with a pipe pistol or shotgun.
But yeah, almost anything could be dangerous depending on how it’s applied.
