  • Hey man, love your gun - can you print me a copy?

    and the implications for the ever-expanding security state . . .





    Cody Wilson holds two of his inspirations: Frιdιric Bastiat's libertarian classic The Law and his AK-74 'individual mandate'.

    Imagine an America in which anyone can download and print a gun in their own home. They wouldn't need a license, a background check, or much technical knowledge, just a 3D printer. That's the vision a cadre of industrious libertarians are determined to turn into reality.

    Last week, Wiki Weapon, a project to create the first fully printable plastic gun received the $20,000 in funding it needed to get off the ground. The project's goal is not to develop and sell a working gun, but rather to create an open-source schematic (or blueprint) that individuals could download and use to print their own weapons at home.

    The technology that makes this possible is 3D printing, a process during which plastic resin is deposited layer by layer to create a three dimensional object. In the past few years 3D printers have become increasingly affordable, and just last week the first two retail stores selling 3D printers opened in the United States with models ranging from $600 to $2,199.

    Spearheading the Wiki Weapon project is Cody Wilson, a second-year law student at the University of Texas. After brainstorming the concept with a friend, Wilson assembled a group of engineers, programmers and designers to develop the printable firearm. Initially the collective, which calls itself Defense Distributed, tried to crowd-source start-up capital on the funding website Indiegogo, but after the project began receiving media attention, Indiegogo froze the group's account and refused to hand over approximately $2,000 that Defense Distributed had raised.

    Indiegogo asserted that the group violated company policy, claiming that the project is related to the sale of firearms. But, as Wilson is quick to point out, Wiki Weapon isn't a for-profit venture and doesn't intend to ever sell tangible firearms. The group's aim is simply to publish a schematic, which would be available online for anyone free of charge.

    Despite this hiccup, Defense Distributed still managed to raise the money it needed from donors by using the direct deposit platform Bitcoin. However, if what happened with Indiegogo is any indication, the project will likely face more legal hurdles in the future. Since 3D printing technology is so new, the legality of the gun publication is still somewhat opaque.

    According to Dave Kopel, the research director of the Independence Institute, it is legal to create pistols, revolvers and rifles at home, although some states are stricter than others. As long as an inventor isn't selling, sharing or trading the weapon, under federal law, a license isn't necessary. Homemade creations also don't need to be registered with the US Bureau of Alcohol, Tobacco, Firearms and Explosives (ATF) and are legal for use by the individual who created the weapon.

    But there are some exceptions to what can be printed legally. Military-grade weapons like machine guns, rocket launchers, sawed-off shotguns and explosives, as well as concealed firearms (like guns within phones or pens) need prior ATF approval before a manufacturer can create them. Federal law also requires "any other weapon, other than a pistol or revolver, from which a shot is discharged by an explosive if such weapon is capable of being concealed on the person" to be subject to ATF review. Since a potential Wiki Weapon would likely be "any other weapon", the ATF would probably have to approve a prototype, and the bureau has said as much.

    Either way, if a fully functional plastic Wiki Weapon is printed, it may be illegal upon creation thanks to an obscure law from the late 1980s. In 1988, Congress passed the Undetectable Firearms Act after the Glock company provoked controversy by selling firearms made with plastic polymers. The technique, which was revolutionary at the time but is common in the industry today, alarmed many gun control advocates who were concerned that plastic guns wouldn't register in airport x-ray machines.

    Gun rights advocates remember the uproar as hyperbolic because Glocks do contain metal, and x-ray machines don't even distinguish between metal and plastic. The legacy of the Glock controversy is a law that mandates that all US guns must contain at least 3.7 ounces of steel. However, the law is set to expire in December 2013. If Congress doesn't renew it, Wilson and company wouldn't have to worry about the legislation.

    "I haven't felt any real heat yet, but I think it's very possible the project might happen outside of America or the files might be hosted outside of America," said Wilson who is cognizant of the statute. "The point of manufacture might also have to be outside of the United States."

    Of course, even if a plastic gun is illegal, it would be incredibly easy to print if a schematic were available. Under US law there's nothing illegal about creating or sharing a schematic for a weapon unless that weapon is copyrighted or patented. Publications like the Anarchists Cookbook and nuclear bomb schematics are available online.

    When asked about the possibility of a Wiki Weapon hypothetically being used by a child or a mentally unstable individual, Wilson, a fierce libertarian, defended the project.

    "People say you're going to allow people to hurt people, well that's one of the sad realities of liberty. People abuse freedom," said Wilson. "But that's no excuse to not have these rights or to feel good about someone taking them away from you."

    Another less hypothetical legal issue concerns the receiver or frame of the gun. In the United States manufactured guns are regulated by serial numbers, which are only printed on the receiver. All other parts of a gun – the barrel, the magazine, the handle, the trigger, etc – don't have to be registered and can be bought by anyone.

    Last year an American gunsmith named Michael Guslick took advantage of this loophole to upload and print out a receiver (technically known as a lower receiver) for an AR-15 or M16. He then attached the lower receiver to other gun components, thereby completely circumventing regulations.

    According to Guslick, after assembling the gun he managed to successfully fire off 200 rounds. In some US jurisdictions, Guslick's experiment would probably have been considered illegal, but what's perhaps most interesting is the implication that today it's already possible, even for someone who has had a gun license revoked, to build their own unregistered firearm at home with printed plastic parts.

    But Kopel expects 3D gun printing to remain a hobbyist pursuit, at least in the United States.

    "If this thing does work I think it would be great for the people in Syria to have a 3D printer so they could start making their own guns and start resisting the mass murderer Assad," said Kopel. "The guy who is robbing a 7-Eleven isn't going to buy a 3D printer."

    According to Peter Swire, an internet law professor at Ohio State University, for the moment 3D printing is just another tool for hobbyists, who have a long history in the US.

    "What's important here is the ability to turn software into a gun anywhere in the world," said Swire. "I think the big question is how many 3D printers are we going to have? The more 3D printers the more gun factories there are."

    It's impossible to know exactly how many Americans own guns because there's no gun census, but it's well-known that the US is the most armed nation on earth with about a third of the globe's guns. Kopel questions whether people will go to the trouble of printing guns out when they are so easily available.

    It's also important to note that building an all-plastic gun is difficult and dangerous. To be successful, the Wiki Weapon will need to be able to absorb the impact of exploding gunpowder and expanding gas, which Guslick doubts could be contained by the type of plastic used in non-industrial 3D printers like the RepRap and Makerbot.

    For Wilson and his team, however, the challenge isn't necessarily to create a practical firearm. Realistically, he said, a plastic gun would probably only work once and have to be disposed of after use. Even if it were to succeed and the team were able to create a plastic gun, he acknowledged that it's highly unlikely that a Wiki Weapon would replace existing commercial models anytime soon. But that isn't why the group is pursuing the project.

    Like many Americans Wilson's family had guns when he was growing up in Arkansas, but he isn't as he puts it, "a guns guy". He only bought his first gun a year ago and most of his childhood was spent "with my nose in a book". Wilson said his interest in making firearms is rooted not in a passion for guns, but in libertarian ideals.

    "In the future no one is going to be able to decide who has a gun but you," Wilson said. "This is a project that intends to help subvert older hierarchies and these older modes of thinking."

    By virtue of his legal training, Wilson is the de facto in-house lawyer for the Wiki Weapon project, and he freely admits that he's not entirely sure if the weapon he's creating is legal. But for him, that's part of the project's novelty.

    "This project could very well change the way we think about gun control and consumption," Defense Distributed states in the "manifesto" published on its website. "How do governments behave if they must one day operate on the assumption that any and every citizen has near instant access to a firearm through the internet? Let's find out."

      I wouldn't be so sure. Not all polymers are the same.

      3D printing sounds great, and it could well be exciting at some point in the future (decades). But I wouldn't recommend firing a gun made entirely out of this stuff just yet.

      The polymers used in 3D printing have to be curable on the fly, unlike the molded/machined plastics in polymer-frame gun components in, for example, a Glock. This means that their fundamental material properties are considerably worse, particularly when it comes to absorbing impact. The materials have to be chosen either for extremely fast curing (in the case of localized material deposition systems (inkjet), or photo-curing, in the case of laser-patterned systems. This means that the polymers that can be printed are not the strong, tough, stuff you might be thinking of when you think of tough plastics like nylon and polyethylene. Instead think of polymers like diazoquinone-based photoresists, or at best PMMA. All those neat side-chains that give the polymers cool curing functionality also get in the way of achieving the highest levels of structural integrity.

      Furthermore, the fabrication process itself works by depositing material in layers, resulting in high pore densities. Even when the process is tuned perfectly to minimize these, diffusion limitations will still create density variations that act as stress concentrators on impact, or under cyclic loading. So not only do the parts begin with weak fundamental material properties, these weaknesses are compounded with poor macroscopic structural uniformity.

      And you can pretty much forget about using such printed materials in any application that might cause material fatigue, like high-cycle automatic or semiautomatic weapons. Their structure is the equivalent of having crack tips not only at the surface of the material, but distributed throughout the entire body of the material.

      As I said, there may be a future in which this sort of thing is interesting for high-strength applications. And even now, for parts that are either massively over-engineered, or don't play a critical mechanical function, they can be fine. But for now, if you want to have a controlled explosion near your head, stick to conventionally manufactured firearms, plastic or otherwise.

        I'm with Astonas.

        Having a reasonable bit of experience with firearms, including a range of modern firearms that include considerable portions made from plastic/polymer...I just don't see we are at or even near the stage where "working parts" such as barrels/bores/receivers can be made from polymer and used safely.

        Many modern firearms are largely plastic/polymer......EXCEPT for the barrel/receiver/gas system "working parts".

        I just don't see it happening...at least much beyond a more effective but equally disposable/temporary firearm like a refined prison/improvised "zip gun".

        On a related by more happy and less crazy note, Makerbot just introduced another new 3D printer(Replicator2):

        http://store.makerbot.com/

        My kids are still too young, but I reckon in a few years when they are ready these 3D printers will be dropping dramatically in price and increasing further in capability.

        I wonder when the big heavyweights of printing like HP are going to come crashing into this space?

        Or will they just buy out Makerbot?

        Owning equity in an outfit like this could be a good investment moving forward, even in this nasty patch ahead.

          Admittedly, there is more processing required, but 3D printing is not limited to polymers.

            Interesting........just to chuck it out there......the requirements to produce a "printed firearm" would require materials that can handle contain pressures of 20-40K PSI for handguns and 50-60K PSI for rifles to avoid catastrophic failure.

                    Toot, toot - right on time, the Crazy Lady Express pushes all the 'right' buttons . . .

                    Disruptions: With a 3-D Printer, Building a Gun With the Push of a Button



                    It has long been possible to make a gun at home. But what happens when it no longer takes knowledge and skill to build one?

                    It won't be long before a felon, unable to buy a gun legally, can print one at home. Teenagers could make them in their bedroom while their parents think they are "playing on their computer." I'm talking about a fully functional gun, where the schematic is downloaded free from the Internet and built on a 3-D printer, all with the click of a button.

                    Hit print, walk away, and a few hours later, you have a firearm. There are no background checks. No age limits. No serial numbers etched on the barrel or sales receipts to track the gun.

                    It might sound like science fiction, but 3-D printers are quickly becoming a consumer product. These printers, which now cost about $1,000, can print objects by spraying thin layers of plastic, metal or ceramics that are built up into shapes. Long used by industrial companies to make prototypes and parts, 3-D printers are becoming faster and less expensive almost weekly. One manufacturer, MakerBot, has set up a retail store in Manhattan. Chinese companies have started making them, and prices are falling to about $500.

                    Hobbyists have printed fairly rudimentary objects: prosthetics, iPhone cases, cat statues and missing luggage clasps.

                    A number of people have already made gun parts using 3-D printers. And yes, the guns with these parts have successfully fired bullets. Cody Wilson, a law student at the University of Texas, is in the process of building a completely functional printed gun. "We hope to have this fully tested and put the files online in the next couple of months," said Mr. Wilson, who runs a Web site called Defense Distributed.

                    He calls the gun the Wiki Weapon. In a video explaining the project's goals, he describes the Wiki Weapon as the world's first "3-D printable personal defense system."

                    "What's great about the Wiki Weapon is it only needs to be lethal once," Mr. Wilson says in the video, in a monotone voice. "We will have the reality of a weapons system that can be printed out from your desk. Anywhere there is a computer, there is a weapon."

                    Under most circumstances, it is not illegal to build your own gun, but it has been pretty difficult. Ginger Colbrun, a spokeswoman for the Bureau of Alcohol, Tobacco, Firearms and Explosives, said people had made firearms out of pens, books and belt buckles. But those contraptions and conventional firearms require a certain amount of knowledge and skill.

                    Ms. Colbrun said the agency was keeping a close watch on 3-D printers. "A.T.F. always tries to stay ahead of the illegal activity and the novel firearms trafficking schemes, without impinging on individuals' rights," she said.

                    But monitoring whether people make their own guns on a 3-D printer is going to be impossible, barring sticking an A.T.F. agent in every home. It's also hopeless to try to build a technology into these printers that prevents people from printing a gun. One project mentioned in Mr. Wilson's video, called the RepRap printer, will be capable of replicating itself by printing other 3-D printers.

                    After committing a crime with a printed weapon, a person could simply melt down the plastic and reprint it as something as mundane as a statue of Buddha. And guns made of plastic might not be spotted by metal detectors in airports, courthouses or other government facilities.

                    "This becomes scary when you consider the fact that it could be yet another opportunity for people to evade background checks and get a gun," said Daniel Gross, president of the Brady Campaign to Prevent Gun Violence and the Brady Center to Prevent Gun Violence.

                    The National Rifle Association did not respond to a request for comment.

                    Given the number of existing loopholes and the ease with which people can buy firearms on the Internet, people printing guns might seem like adding a drop of water to an Olympic-size swimming pool. According to an annual report released by the A.T.F., more than 5.5 million guns are made in the United States each year, and millions more are imported.

                    "Forty percent of guns are sold through a loophole at gun shows, where people are already able to buy a firearm without having to go through a background check," Mr. Gross said. "There's already a permanent 'gun show' on the Internet."

                    Michael Guslick, an amateur gunsmith who has written extensively online about the considerable challenges of 3-D printed guns, said people had been experimenting with homemade guns for some time. He said the most notable example was the zip gun, which is made from off-the-shelf plumbing parts. (Not surprisingly, the schematics and instructions can be downloaded online.)

                    "This is just applying a different technology to something that is already being done," he said. "But making one on a 3-D printer is a lot of work when your local plumbing department is so close by."

                    For now, the task isn't as easy as hitting print, say the few people who have successfully built guns using 3-D printers. The basic problem is not the printing technology, but the lack of plastics strong enough for a real gun.

                    But this year, Mr. Guslick managed to print some components for an AR-15 semiautomatic assault rifle - the kind of gun used in the Aurora, Colo., shootings - on a 3-D printer. He used ABS plastic, "the same plastic used to make Legos."

                    He was particularly interested in printing a part called the lower receiver, which connects the trigger, grip and magazine holder. "I used my home 3-D printer to make the lower receiver, which is the only regulated component of a gun," he said. "Every other part you can legally pick up at your local gun shop."

                      Re: Hey man, love your gun - can you print me a copy?

                      In a film version of "A Connecticut Yankee in King Arthur's Court" the time traveler, played by Bing Crosby, makes a hand gun at the local blacksmith's shop - alas sans 3-D printer . . .






                      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.

                      The fuss around the printing of guns shows the real impact 3D printing will have on our daily lives. By expanding the realm of "digital" goods into the physical world, it extends the questions we've been struggling with when it comes to the internet – how to control the instructions for hacking copy-protection, encrypting files or making bombs (those last instructions apparently followed by the Tsarnaev brothers in Boston to lethal effect) – to a whole new area.

                      The wargaming company Games Workshop has to come to terms with 3D printing of its miniatures in the same way that Paramount Pictures and Warner Music Group are starting to acknowledge that a certain level of piracy will always be endemic.

                      While there are downsides for some, others benefit greatly. Initiatives like Project Gutenberg or Google's plan to scan every out-of-print book in the English language have vastly increased the proportion of human knowledge available to the average person; and if you're struggling to refurbish a century-old car, the fact that the company that made it hasn't existed for 30 years will no longer stop you from being able to print off the right part to get it running again.

                      Ultimately, trying to pin down whether 3D printing is good or bad is like trying to answer the same question for the internet, telephones or the postal service. Some livelihoods will be transformed, others ruined; the only constant will be the change it brings.

                        I'd bet they'd rather buy a real one on the black market or just seal something. Basically, if the cops aren't using it it doesn't work, keep that in mind as future "gun safety" bills work their way through our ignorant politicians. If it works well enough for cops you can most likely trust it (not that bureaucrats don't force failures on cops on occasion).

                        The early ages of firearms are rather bleak due to poor metallurgy. Printed metals are far from the strength of forged steel and current polymers are not even close.

                        These digital fear mongers are stupid. If you're going to build something that's unreliable and good for only one shot why make one that's unreliable and exceedingly loud and requires you to buy ammo? There are plenty of ways to make single shot weapons that are more reliable and much quieter with digital printing technology.

                        I'd guess you'll see things using 11g CO2 cylinders as the propellent and slightly larger projectiles before you see functional firearms.

                        And as I've noted before, felons are already allowed to buy and drive cars, hatchets and Bic lighters. Just because someone is a "felon" doesn't mean he's out to kill every human he lays eyes upon. Most "felons" would be no more dangerous with a gun than they are with a car, an ax or a pressure cooker.

                        Felons are all over the place.

                        BTW -- We looked up the most recent "sex offender" list for our area. Most of them are just perverts, but if you looked at the little polka dots on the map without doing any research you'd freak out. It's yet another worthless idea gone fad.

                          The was an article last year about a guy who made a $5 zip gun then promptly turned around and gave it back to the police for a $200 gift card at a gun buy back.

                          Printing a gun is for folks with too much time and money on their hands.

                          A more enterprising "poor" criminal can mock up a zip gun out of paper mache.

                            Shotguns operate in the vicinity of 10K PSI. At 15K PSI, the strength reported for some feed-stocks, a polymer shotgun is not out of the question. But don't worry, manufacturing firearms requires a license so there shouldn't be any concern of these "deadly gangster style" shotguns falling into the wrong hands.

                              I looked up one of these fellows near me. Turns out when he was 17 he knocked up his 14 year old girlfriend. Go figure.
