3D printing has been made possible and people are finding some interesting ways to do it. The technology may have been done before but they have made it possible for people to buy a machine thats compact enough to fit in any large sized room that will print you actual 3D copies. These guys may have just made the world more dangerous at least when it comes to guns and some of the problems that come along with them. This is definitely worth watching if GUNS is a topic you are interested in.
