    A Gun from the Printer ? Hardly... but read on

    http://www.extremetech.com/extreme/1...3d-printed-gun

    An American gunsmith has become the first person to construct and shoot a pistol partly made out of plastic, 3D-printed parts. The creator, user HaveBlue from the AR-15 forum, has reportedly fired 200 rounds with his part-plastic pistol without any sign of wear and tear.

    HaveBlue’s custom creation is a .22-caliber pistol, formed from a 3D-printed AR-15 (M16) lower receiver, and a normal, commercial upper. In other words, the main body of the gun is plastic, while the chamber — where the bullets are actually struck — is solid metal.

    The lower receiver was created using a fairly old school Stratasys 3D printer, using a normal plastic resin. HaveBlue estimates that it cost around $30 of resin to create the lower receiver, but “Makerbots and the other low cost printers exploding onto the market would bring the cost down to perhaps $10.” Commercial, off-the-shelf assault rifle lower receivers are a lot more expensive. If you want to print your own AR-15 lower receiver, HaveBlue has uploaded the schematic to Thingiverse.

    HaveBlue tried to use the same lower receiver to make a full-blown .223 AR-15/M16 rifle, but it didn’t work. Funnily enough, he thinks the off-the-shelf parts are causing issues, rather than the 3D-printed part.

    No doubt we will return to the days of the panic that surrounded Glocks when they were first introduced.

    Unless you have a CNC machine too it's a very academic exercise. Think about the plastic parts on the steyr, less durable versions could be printed but you'll still need a barrel/housing group etc etc
    Everyone who's ever loved you was wrong.

    You can create designs on CAD software and email it to companies who specialise in adapting those designs to 3d printing. Recently developed processes allow titanium sintering of 3d printed components and complete assemblies. A quick google search will give more info.

    Can you print a spoon?
    OK Smith it’s Colonel Decker. I hate it when a plan comes together. You’re surrounded. I want you and Peck and Baracus, to throw out your weapons, all the ration packs you stole and come out with your hands up. You have fifteen seconds.

    People have designed 3d printable springs that weren't all that effective, but they'll figure it out soon. In the example trellheim posted they used commercial magazine springs.
