I just read an article that says a company called Solid Concepts makes a 1911 using a process that is(I think) similar to injection molding, except with metal not plastics/polymers.
The article says the parts have to be "cleaned up", which I interpreted as deburring and polishing.
Solid Concepts has a FFL though, so it's completely legal.
When someone builds and proves a replicator(like on Star Trek), then I'll be impressed.

That's pretty much what this article says. Kind of neat actually. I can see how it would change things, especially things like knife blades and such that could benefit from layers of varying metals. Maybe even a better bullet. Things that are stronger, yet light weight; Who knows where it could lead?
I don't know why people want to ban it though, just because they used it to make a gun.
Maybe they're afraid it'll hurt business?
Lol, all that technology and they used rubber bands and string to test fire it.
