Supporters of the bill say it's necessary to thwart convicted felons who use 3D printers to develop untraceable "ghost guns."
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.
Zip guns have existed for a long, long time, but nobody's going to legislate serious controls for buying building supplies. I could walk into any hardware store and come out with the materials to build a gun that fires real bullets.
