Working Handgun Printed On a Sub-$2,000 3D Printer

Just a few weeks after Cody Wilson and friends successfully fired an instance of their own 3-D printed handgun design, Sparrowvsrevolution writes, "a couple of Wisconsin hobbyist gunsmiths have already managed to adapt Defense Distributed's so-called Liberator firearm and print it on a $1,725 Lulzbot 3D printer, a consumer grade machine that's far cheaper than the industrial quality Stratasys machine Defense Distributed used. They then proceeded to record their cheaper gun (dubbed the 'Lulz Liberator') firing nine .380 rounds without any signs of cracking or melting. Eight of the rounds were fired from a single plastic barrel. (Defense Distributed only fired one through its prototype.) In total, the Lulz Liberator's materials cost around $25 and were printed over just 48 hours."

    In 1994 a friend and I assembled a .22 from hardware store pipe, a hacksaw, a drill, some nails, and springs. It had a hammer and a trigger. We followed no plans...we just knew you needed a barrel, and something to smack the rim of the bullets we had...and we improvised. It worked fine, but you have to unscrew the barrel to to reload its single shot.

  8. here's a question by slashmydots · · Score: 2, Insightful

    Everyone is freaking out like before this you needed to be God himself to create a firearm. How long does it take a gunsmith to build a gun from scratch? Compare that to the time it takes to design one in AutoCAD or whatever and then 3D print it and assemble it. It's probably pretty comparable and the metal one doesn't look like a bad sci fi prop. I bet I could design a working rifle that would fire a couple bullets from a trip to the hardware store, or especially a shotgun! You need a barrel, aka steel pipe. Then a handle so solder/glue basically anything on. Then you need an end cap with a semi-sealed firing pin to strike the bullet so a piece of scrap metal and a spring. Tada, gun (at about the same reliability level).

    I wouldn't be surprised if some type of DRM appeared on printers to prevent this

    3D-printers are actually pretty easy to build even at home and if you build one of your own there wouldn't be any sort of a DRM.

    The DRM could look for blueprint designs by hash, or certain "gun-like" items.

    Impossible. There is no way for the printer or the software to know what the parts will be used for. There is no universal definition for "gun-like" as even a simple, straight tube would be "gun-like."

    No, but neither is fertilizer when you get down to it. I'm about to go on a tirade for a position that isn't really even mine:
    Gun control is about impulsive people.

    You're never going to stop a McVeigh of Bin Laden with gun control. They're meticulous planners who will not be impeded by inconveniences, and will work around them. They'll build their own materials, circumvent safety control systems, and seek to maximize damage. Those people aren't the most common problem. Their problem is that they are certain that their cause is just.

    The most common thread in criminals, particularly murderers, is poor impulse control and emotional volatility. People kill because they get angry, or desperate. 3/4 of people who attempt suicide will be deterred by a simple obstacle or obstruction in their way. People being rational don't murder. Gun control is about limiting the ease with which someone can engage in irrational acts.

    Is this a gun, as in a fully functional and useful tool? No. But it's not proof of any kind that 3d guns are impractical in principle (as that Register article claims); quite the contrary. The Liberator proved that it's possible to print a gun that can be fired (unreliably) on a printer, without blowing up. The Lulz version proves it is possible to create one that can be fired repeatedly, and can be created on a consumer grade printer. From here on in the reliability will improve, and perhaps someone will come up with a double barreled one or a six-shooter even.

    This development is not interesting for gun enthusiasts. It may be interesting for people who need to smuggle a gun past security (you still need to get the metal parts + cartridges through the detector). It's not that interesting for people with the skills, tools and smarts to build their own gun, nor is it for criminals who can (in most countries) quite simply acquire a gun from an illegal source. But it is very interesting for people who want to acquire a gun illegally, not necessarily because they want to use it for criminal purposes, but in case they want one to defend themselves but the gov't doesn't let them have one.

    And for that purpose, you wouldn't really need something that can reliably fire 10.000 rounds. 6 reliable shots would already be a vast improvement over nothing at all. And given the progress already made on these printers, I'd say that printing and assembling such a gun by anyone may well be viable in a few years.

    It's a lot easier to take away guns from irrational people than it is to get them to control their impulses. When you figure out how to get irrational people to control their impulses, let me know.

    I don't know where you get the idea that gun banners don't care about addressing the base cause of violent crime. The people who led the effort were doctors who got tired of having people dying from gun wounds in the emergency room. They were happy to reduce violence any way they could do it. The easiest way was to start by taking away the guns.
