3D printing has ramifications beyond firearms. In theory there are thousands of products that we currently buy which could be “printed” at home and assembled.
A good friend of mine works for a company that does just that, he is the actual machine/equipment operator. He is always regaling a few friends like myself of what he has been making and how well these items work in reality, how the technology is continuing to improve. He has told us on a number of occasions that 'some' in his trade have indeed done exactly what is being discussed here. He says it is something that must be seen to be really appreciated.
Read that drugs could also printed...scary thought if possible
