The first printed barrel can already take 9 shots so I say we'll see one within a year if the fascists don't cripple 3D printing.
Maybe the printed items can be tracked back to the individual printer?
They can't. You can build your own printer if you are so inclined. This 3-d printing stuff has a large opensource communitity behind it.
Think linux, writ small, like the early days when I was downloading a few disks to build a system.
Linux was international before powers tried to kill it.
I believe FR is running on linux.
This is international. It's global. 3-d printing is here to stay, regardless of the politicos.
The only thing to determine is the cost in blood and treasure.
We’re also going to need field expedient ammo - black powder in a cartridge, maybe for use in a multi-barrel setup. Chris Rock anticipated the anti’s next move - bullet control. http://www.youtube.com/watch?v=VZrFVtmRXrw
