Edit, reading further it's even more insane:
> The New York definitions sweep in not just FDM and resin printers, but also CNC mills and “any machine capable of making three-dimensional modifications to an object from a digital design file using subtractive manufacturing.” That’s a lot of shop & manufacturing equipment!
This is the dumbest thing I have ever read.
Even in countries with strict gun control, like the UK, the most serious criminals can get hold of guns. And if lesser criminals 3D printed a gun, they'd struggle to get hold of ammo for it. So they stick to knives.
