NY bill would require a criminal history background check for the purchase of a 3D printer::Requires a criminal history background check for the purchase of a three-dimensional printer capable of creating firearms; prohibits sale to a person who would be disqualified on the basis of criminal history from being granted a license to possess a firearm.
No, they’re much harder. There’s a lot more to know about the material you’re using and how that effects feed rates. It’s easier to crash the head into the material, so you have to pay attention to the path it takes. Knowing how to square off the stock to the needed precision is a little skill all its own. The software on the cheap Bang Good machines isn’t nearly as well developed as 3d printer slicers. Those are really for plastic or wood; they can kinda do aluminum, but not well, and certainly won’t do steel. The software on more professional machines (Tormach and such) is extremely complicated. You also need a constant supply of lubricant for metal, which gets messy if you don’t have a setup for it.
My makerspace doesn’t let you touch the big Tormach until you’ve had some experience on the manual mill first (or otherwise have previous experience). Conversely, the little Carvey CNC we have can be taught in an hour, but it’s mainly for wood or engraving metal, not cutting metal.
