They do 3D metal printing, too. Obviously, the 2 major issues will be giving some power back to the little guy (corporations and their bought-and-paid-for governments hate the idea) and patents. By the way, I'll have to get into reloading, especially if I get the Norinco Type 97 next spring. 5.56 costs double what I'm getting milsurp 7.62x39 for. Eventually, I'd even buy some Prvi and reload 7.62x39 for accuracy at the range. For now even a single stage will do. I don't go through more than 200-300 per week. If I get into handguns, I'll get into progressive. Just sold my only handgun because it was a safe queen. Too much fun with the rifles.
