New York Bill Would Require a Criminal Background Check to Buy a 3D Printer (gizmodo.com)

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.

Do I need a background check to buy a CNC? Or a lathe?

I mean, kind of, yes. CNCs have been one of the big items for export controls. Especially if they can be used to build weapons, parts for nuclear subs, etc.

Generally speaking, lathes and milling machines must be licensed for export if their accuracy exceeds six microns. Grinding machines are controlled at four microns. The Wassenaar Arrangement controls all machine tools capable of simultaneous, five-axis motion, regardless of machining accuracy.

six microns

Given that human chromosomes are on the order of 5 to 10 microns, I am thinking this export regulation doesn't apply to the hobby market. This is "use the machine in a clean room" level precision.
