Picture I https://kirjabloggaus.blogspot.com/ Kimmo Huosionmaa The United States Of America has legalized the 3D-printed weapons. Manufacturing the 3D-printed weapons is quite expensive, and there is needed 3D-printer, what can produce steel parts. That thing is a modified MIG-welding machine, and it's quite expensive. Also, the system needs the CAD-models of every single part of the gun, and then the system must be sharp enough, that the parts would be fitted together. This is why normal people must not be worried about this technology, and that kind of systems are actually so expensive, that lone gunmaker would not have change or willing to pay the prize about that machine. When we are thinking about the tests, where the guns are made by using 3D-printers, the parts of the weapon have been scanned by using laser scanners for taking precise right form and dimensions of every part of that weapon. So this is the very expensive project, and that's why would be easier...
