Well, I imagined this would happen at some point...someone has now posted the Print-on-demand 3D printer file for both an AR magazine & a lower receiver.

Lower: AR-15 Lower Receiver by KingLudd - Thingiverse

3D printers are really becoming more of a reality now, and they are doing more than just plastic parts, some of the industrial type machines can do metal parts too. They can do fairly precision parts now, here is a great example:
High Quality Pliers by russrobot - Thingiverse

The coolest thing is that in theory, with the plans/parts file a machine like this can print out the parts to make duplicates of itself(minus the electronics of course).

In case you are wondering, the printers are still a bit expensive from $1200 for a full kit to ~$2250 and up ready to run. Some are starting to be made in China and thus the price for an at home model is coming down fast. (see this one: Personal Portable 3D Printer

Here it is in action:

Plastic parts make good cores for making your casting molds. Jay Leno uses a scanner and 3D printer to make his own replica car parts for some of his classic cars. Autozone don't exactly stock an exhaust manifold for anything before WWI.... He scans the part he does have into a 3D model, draws in the missing pieces, then prints out a prototype to check for fit. He then uses it to make a casting mold, or sends the program to his CNC center to mill it out of solid material.

OH, and yeah just to balance things out, 3-D printing isn't alawys as easy as it looks. Calibration, printing platform temp., extruder temperature, raw material differences can all add up to bad prints and wasted time. See these FAILS at Flicker for some reality checks... Bottom line: don't expect to buy one and then just start print out perfect parts like clockwork, you will be tweaking and adjusting, and trying to get things just right.
