3D Printed Rifle Breaks After 6 Shots

If you HAVE an AR 15, you can take it down and scan it and produce the parts.

You can scan parts that you have, but chances are that the scan won't have the precision needed for a firearm. I'd bet that the 3d printer files started from the blueprints instead of scans of actual parts. That's more precise and probably easier than scanning.

BTW, 3d printer files are pretty easy to get

3D precision scanners are becoming ever more common and prices continue to fall.

As for feeding the 3D printer, we use Solidworks and Rhino3D..the same design programs that we use to feed our CNC machines. Having an original drawing of a part allows you to create the 3D model, of course,...

How One Group Is Trying To Skirt Federal Regulations On Its $50 3-D Printed Gun Part | Popular Science

Enthusiasts of gun-law loopholes, this might be your new favorite workaround. A project at the crowd-funding site Rockethub wants to create a 3-D printed gun part for just $50. The twist: the part is only 80 percent complete, so like an Ikea desk you'll have to finish the rest of it yourself.

Started by 2nd AM Arms, the project promises to make a lower receiver for an AR-15 semiautomatic rifle. The lower receiver is what holds all the working parts in a gun. The receiver is so important that under U.S. law, a receiver on its own is still treated as a firearm, and requires a serial number. The argument made by 2nd AM Arms, however, is that an 80-percent completed receiver is just part of a gun component, not a full-blown firearm, and as a such is not subject to the same degree of federal regulation.
...
Making the lower receiver is only one of the goals of this project. Obviously, there's a larger agenda here: to send a political message. Just look at the other donor rewards. At the lowest level of support, 2nd AM Arms will mail a copy of the 2nd Amendment to President Obama and Sen. Dianne Feinstein (D-California), both of whom have expressed interest in stricter gun laws. All higher pledge levels include T-shirts featuring the 2nd Amendment, and if you pledge anything above $50, you get a commemorative lower embossed with the 2nd Amendment. Finally, if the project meets its funding goal (which it had as of press time), 2nd AM Arms pledges to donate 2 percent of its funding to the NRA.

You couldn't come up with anything more original for a vanity plate than "SAMPLE"??

You going to have a bumper sticker that says BR-549??
