"You can make AR lowers out of high grade plastic but not the uppers and guess which part if regulated? Yep, the upper. Without the upper, an AR is not a firearm."

3d polymer/plastic printers are well established in the corporate prototype realm, and hobbyists are making inroads with DIY models.
As someone else mentioned, the 3d designs that work for 3d printers are likely to be easily converted to CAD/CAM files. Combine the easily printed details of a 3d model and the 'designed for easy manufacturing' aspects of the AR lower I saw that was made of cut up cutting boards, and you shoudl be able to create a set of fairly simple CNC shapes that you can bolt together. Imagine - a simple machined metal AR15 lower kit you can assemble with a few screws. |

Technologically, we are maybe 10 years away from a store that sells anything.
I don't mean the internet, which already sells everything. I mean a storefront, right down the street from your house, that will sell anything. You go on the website, put in your order, and it gets thrown into the manufacturing queue. The machine spits out your order a few minutes later. You can pick up for no extra charge, or your order can be delivered, perhaps along with a pizza. You pay onlyfor machine time and material cost, potentially making some specialty products incredibly cheap. Next day shipping is so last decade. How about next hour delivery? |

I was hoping for a centerfire weapon in an intermediate cartridge, likely 5.56 or 7.62x39, something that could use existing mags. I'm basically imagining a homemade Masada with a printed metal receiver rather than a molded polymer one. Remember, we have processes like Scanline Sintering now that allow the production of use-ready metallic parts, so we're not stuck with plastics and polymers even now - they're just expensive as hell. I won't be surprised if we have the affordable rapid-prototyping equipment in the near future to print barrels that are more structurally precise than even the best cold-hammer forged blanks, with the only remaining necessary step being heat-treating... something that can be done with a homemade forge made from bricks, a thermometer, charcoal, and a blower fan. "A fighting rifle out of every home printer" is less than 10 years away. And then the BATF might as well just abandon the F, because they'll be all but powerless to regulate or track anything. |

Wait til some toolbox does his own "tweaking" of the upper, or his "printer," doesn't have the right settings, or any of 5,000,000 other ways this could go very wrong, and the gun blows up in his face. Large firearms manufacturers spend millions of dollars annually on quality control and design testing (by people qualified to do the job) to ensure that the firearm delivered to you is safe to use. I'm not entirely sure this is any different than homemade explosives by some amateur pyro with a chemistry set he bought online... Soon, these AR's will be Glocking like nobody's business. |

You can get the igs format files at cncguns.com for AR lowers and uppers.
I've taken those igs files, joined them, and saved as .3dm in Rhino. Just playing around, mind you, to see if it can be done. It can. Once you do that, with some cleanup, you can 3d print using a 3d printer. No big deal. A more reliable, sturdy output would be done on a cnc mill, which is also tens of thousands of dollars cheaper than a 3d printer. A universal, printable weapon is probably already on someone's hard drive, just waiting to be disseminated. You can't stop the signal, to quote a rather subversive movie. 
Best, JBR |

Considering the quality of the "3D printers" I've seen, I just don't see how the people making these expect them to fire reliably, to hold a magazine securely in the proper orientation, and to not bend when the buffer slams back and forth repeatedly. Metal inserts would solve the FCG and magazine well dimension problems, but not the stiffness. |
