Freedom

I'm definitely behind the times and just catching up, but a user on AR15.com used a 3D printer to print a functioning AR-15 lower receiver...and the print file is free to the public.

This whole 3D printing thing is amazing. For the same cost as a nice plasma TV you can buy a 3D printer for home use and print cups, plates, forks, replacement oven knobs, cell phone cases, bicycle chains....and AR15 receivers.

Potential illegalities aside, consider the near impossible regulation of 3D printers and their use for printing hi-cap mags, lowers, and other neato things that would ultimately serve to protect our freedom.

I just saw a news story on this. Amazing...

Ok I guess im not that smart could someone tell me the purpose of printing a 3D pic of a mag or lower please, or am I missing something here?

It's an actual functioning piece of equipment .

On a mag the only required item to make it work was the spring.

Basically u would draw it to the exact dimensions in inventor of solid works. We used autocal inventor then it actually prints a 3d object! Pretty cool we made some things like valves and small pump pieces and gear sets at TJC. So for the Mags you would be printing the spereate pieces out of the plastic material or "ink", suck as bottomn, Actual mag case, and follower then all u would need is a spring or buy a pmag follower kit. For mags and stuff I'm sure someone already has it drawn up in a file.

3D copying is right around the corner. The output technology is here, so the next step is a 3D laser scanner, maybe something like a home MRI in which you could place, oh say the bottom half of a Glock, and then print 10 copies. It's all just a matter of how easily the print file is created. Legality would of course be an issue, but if the technology is available, don't think that the cartels won't exploit it.

We're about to enter a new era in manufacturing folks

WOW!! That is pretty neat....

That is nuts, and a little scarey, but awesome...
