Didn't think I'd find this kind of FUD there, but then this is the new America, why am I surprised?
The FUD part:
"For instance, a user on Makerbot's Thingiverse, a site where users share potentially useful 3D models for others to print out at home, posted the plans for printing a magazine for an AR-15 rifle. A fully automatic AR-15 can fire 800 bullets a minute. While the posted model held just five rounds of ammunition and was completely legal, extending the magazine to hold fifteen, or even more rounds by modifying the model, would be easy enough. Under the now-lapsed Federal Assault Weapons Ban, possessing any magazine containing more than ten rounds was illegal. In response, another Thingiverse user posted a model for printing a part called the lower receiver for the AR-15.
If, like me, you're not very knowledgeable about guns, that may not sound like much. But from a legal perspective, the lower receiver is actually pretty interesting. You could purchase at gun shows or from mail-order catalogs—without any sort of record—every part of this rifle except the lower receiver. By printing out the lower receiver of an AR-15 on a 3D printer, it's possible to complete construction a fully functional, unregistered AR-15.
3D printers can now help a bad guy break into your home, steal your money, and even assemble an unlicensed automatic weapon. Clearly it's time to pass some laws that limit what these things can do, right? Not so fast."
