    Ok so it doesnt work yet... but here is an article from MSN.

    3-D printed gun fires 6 shots — then falls apart

    The idea of using a 3-D printer to create a gun is controversial and interesting, but it seems to still be a ways off from equaling the quality of machined parts. A gun with a major part printed that way failed after just six shots when some enthusiasts decided to give the tech a try.

    Creating a printable gun is the project of Defense Distributed, which is working on what it calls the WikiWeapon. But the effort isn't far enough along to create a working firearm, so Defense Distributed used a design created by another printed-gun creator who goes by the name HaveBlue.

    HaveBlue claimed in July to have fired his printed gun hundreds of times, which doesn't seem impossible given the quality of the printing. The part printed by the group is called the lower receiver, which is where a round is received from the magazine. Pictures show it to be very well made, and it appears to fit exactly to the other parts in the gun kit they used.

    But the pressure of the recoil appears to have been too much for the "buffer ring," which separates the stock from the upper receiver. After firing just six shots, the gun split in two. It's a serious setback, especially considering they were firing a lower-caliber cartridge than the gun would normally shoot.

    The legality of all this is unknown, not to say in dispute. It is legal to create your own firearms, but not to distribute them — and in the case of printed guns there's a bit of both going on. The ATF is looking at the subject, but for now it's all something of a grey area.

    The technical aspects of the part, the failure, and the team's plans to improve it can be found at Defense Distributed's blog. You can watch the video of the test below.

    Do you understand how much a prototyper cost? This is not something just anyone can walk into best buy and toss out the master card and carry it home.

    Do you understand that you have to have a CAD drawing to do this. Most use special propitiatory software that cost $5k+....

    We used Solid Modeler, which cost a ton per station, and looked into something like this for prototyping. The only advantage was speed, because maintaining a model shop with CNC equipment was cheaper, at least thus far.

    I did read of one use that makes sense.
    Have one of these on the space station, or on the base on another planet.
    When they need a tool or very special part, the earth-base transmits the data to their printer and makes the part on the spot. MUCH cheaper and faster than flying it up to them.

    But the technology is FASCINATING!!
