3D-Printed Gun Successfully Fired

3D-printed-gun-liberator

The gun which was created using a 3D printer has been tested and successfully fired:

The world’s first gun made almost entirely with a 3D printer has been successfully fired in the US. But it’s not going to herald an age of widespread weapon ownership, and it’s certainly not proof that 3D printing technology needs to be controlled for our safety.

The gun – called the “Liberator” and produced by Defense Distributed, a group that describes itself as aiming to “defend the civil liberty of popular access to arms” through “information and knowledge related to the 3D printing of arms” – is the second to have made the headlines in the past year. In July, an American gunsmith printed the lower receiver for an AR-15, a type of modular assault rifle popular among enthusiast. Although not capable of firing on its own, the part is the only component legally considered a firearm in the US, so the rest of the gun – the barrel, trigger, cartridge and so on – could be bought without a licence.

The Liberator is a more serious prospect. All of the necessary parts can be printed from a 3D printer except for the metal firing pin, which is made from a single nail. (In order to comply with US laws, the gun as produced also has a 175g chunk of steel inside it, so that it doesn’t evade metal detectors). It is a fullblown gun, and recognisably so.

But technologically, it’s still simple. That’s because the principle behind a gun isn’t too tricky: load a bullet into a reinforced tube, and whack the back of it hard. That’s an engineering problem street gangs in the 1950s managed to solve with wood, antenna housings and elastic bands, building “zip guns” to shoot at each other; and it’s also the basis for converted air rifles and cap guns. The difficult stuff – getting it to fire accurately, repeatedly and without jamming or blowing up in your face – is still a long way off for 3D printers. And even the best 3D-printed gun still relies on someone else to make the gunpowder.

Here’s the video:

Now that this technology is out of the bottle and in the public domain, controlling it is going to be next to impossible.

    I’ve been reading a lot about, and listening to interviews with, Mr. Cody Wilson regarding his plastic gun.
    He fully admits that his gun is substandard to traditionally made firearms, however he makes an argument that one day soon technology will exist to make firearms at home that are just as deadly as commercially made firearms. He claims he is making an ideological argument that with today’s technology, gun control measures may not be as effective as proposed.

    His best argument lies not with a fully homemade pistol, but with large capacity magazines. If high capacity magazines were banned, what is to stop someone at home from manufacturing a 30 round clip made from plastic and a spring? And if one had nefarious purposes in mind, who cares if it lacks durability – all it needs to do is last for one use.

    I don’t necessarily agree with Mr. Wilson’s ideology, but at least it is reasoned and consistent.

    Cheers.

    If the argument is rational, it can only be by projecting 3-d printers far, far, far, beyond anything available today.

    Not even high end commercial printers can do plans-in-guns-out. They can produce metal parts (with voids!), which a skilled gunsmith could assemble. It is possible that such a gun could handle low pressure rounds. But a teenage spree shooter is not going to “print a gun and go.”

    (Note that high capacity magazines require high tolerance springs, which cannot be printed on any machine today.)

    There were those who didn’t want a product made from stamped parts not hand fitted, but now millions fly across the landscape at high speed in the same product made with a lot of plastic. Don’t you worry about it, the youngsters will innovate while you sit about stewing in your own juices.

    No they don’t. In any case, the printed high capacity magazine was demoed months ago. Fed like a champ.

    You might argue such “high tolerance” for long reliable service life. No one is going to carry a printed gun for self defense for the time being. But then a hundred years ago, there were those who derided those fancy automatic pistols as never being reliable enough to replace to old six-shooter revolver.

    @Doug Mataconis:

    You misunderstand.

    Let’s back up. In the beginning there was the SciFi concept of a matter replicator. Wouldn’t that be neat? And so people started to project how it could be done without Star Trek magic. The idea they came up with (just conceptually now) was that products would be printed in 3d. You could print yourself an iPad, or anything.

    That was a neat enough idea that people started working on it. Someday they may get to the replicator, and you may be able to do plans-in and iPad-out, or gun-out.

    But everything 3d is not equal. Think about the 3d things in your life now. You may go buy a cap for the cat food can at the 99 cents store. You may still drop hundreds at the Apple store.

    Right now, the best any 3d home printer can do is make that 99 cent cover for your cat food can.

    People have been “innovative” in trying to make things work in cheap plastic, but that is not at all the same as making the home printer work in steel, let alone in dynamic mixes of materials, anytime soon.

I also know that we made guns out of some pretty terrible quality metal through the centuries. During WW1 and then WW2 the steal being used was of serious inferior quality to what we can do today. That inferior steel has held up in guns such as the mosin nagant which has been around since 1891 and fires a high powered 7.62x54r cartridge that is lethal out past 1000 meters.

    I’d like to note that after all Matt’s bashing of me, he admits here what I said in the other thread:

    our material technology allows for us to “3d print” metal parts that are almost as strong as cast steel

    That is less than cast steel, and of course less than forged steel.

    Commercial firearms use forged steel for their barrels and many of their parts, and so not even the high end commercial 3d printers can truly replicate them. To make a gun, you’d have to make a blocky design compensating for weaker materials.

    Barrel Making: The Rise of Steel Barrels

    [In the late 1800's] Mr. Whitworth was the eminent mechanical engineer of his day and came up with a way of producing a stronger cast steel. His process consists of melting a steel ingot into a mold and applying pressure of up to 6 tons/sq. inch to the mold while the steel is in a liquid state. The pressure drives out all the gases and eliminates blowholes in the cast steel.

    Survivorship bias is the logical error of concentrating on the people or things that “survived” some process and inadvertently overlooking those that didn’t because of their lack of visibility. This can lead to false conclusions in several different ways. The survivors may literally be people, as in a medical study, or could be companies or research subjects or applicants for a job, or anything that must make it past some selection process to be considered further.

    Survivorship bias can lead to overly optimistic beliefs because failures are ignored …

    The only reason this technology would be used to make a gun is to A) make a point (not what guns do) or the B) avoid regulation for nefarious purposes.

    Hell there’s plans on the internet for barrel construction using simple pieces of pipe.

    All of this is completely mute as barrels are easily purchased. In a lot of cases (such as the ar-15) the only part that qualifies as a gun is easily made in plastic. The rest of the ad-dons can be purchased separately without IDs or tracking involved.

    So yeah keep fighting about printing barrels when the reality of a home printed gun is already here.
