This Is The World's First Entirely 3D-Printed Gun

May 07, 2013  -"Forbes" - Eight months ago, Cody Wilson set out to create the world’s first entirely 3D-printable handgun.

Now he has.

Early next week, Wilson, a 25-year-old University of Texas law student and founder of the non-profit group Defense Distributed, plans to release the 3D-printable CAD files for a gun he calls “the Liberator,” pictured in its initial form above. He’s agreed to let me document the process of the gun’s creation, so long as I don’t publish details of its mechanics or its testing until it’s been proven to work reliably and the file has been uploaded to Defense Distributed’s online collection of printable gun blueprints at Defcad.org.


All sixteen pieces of the Liberator prototype were printed in ABS plastic with a Dimension SST printer from 3D printing company Stratasys, with the exception of a single nail that’s used as a firing pin. The gun is designed to fire standard handgun rounds, using interchangeable barrels for different calibers of ammunition.

Technically, Defense Distributed’s gun has one other non-printed component: the group added a six ounce chunk of steel into the body to make it detectable by metal detectors in order to comply with the Undetectable Firearms Act. In March, the group also obtained a federal firearms license, making it a legal gun manufacturer.

Of course, Defcad’s users may not adhere to so many rules. Once the file is online, anyone will be able to download and print the gun in the privacy of their garage, legally or not, with no serial number, background check, or other regulatory hurdles. “You can print a lethal device,” Wilson told me last summer. “It’s kind of scary, but that’s what we’re aiming to show.”

Since it was founded last August, Wilson’s group has sought to make as many components of a gun as possible into printable blueprints and to host those controversial files online, thwarting gun laws and blurring the lines between the regulation of firearms and information censorship. So far those pieces have included high capacity ammunition magazines for AR-15s and AK-47s, as well as an AR lower receiver, the body of that semi-automatic rifle to which off-the-shelf components like a stock and barrel can be attached.

Those early experiments have made Cody Wilson into one of the most controversial figures in the 3D printing community. In October of last year, Stratasys seized a printer it had rented to Defense Distributed after the company learned how its machine was being used. New York congressman Steve Israel has responded to Defense Distributed’s work by introducing a bill that would renew the Undetectable Firearms Act with new provisions aimed specifically at 3D printed components. In January, personal 3D printing firm Makerbot removed all gun components from Thingiverse, its popular site for hosting users’ printable designs.

All of that opposition has only made Wilson more eager to prove the possibility of a 3D printed firearm. “Everyone talks about the 3D printing revolution. Well, what did you think would happen when everyone has the means of production?” Wilson asked when we spoke earlier in the week. “I’m interested to see what the potential for this tool really is. Can it print a gun?”

It seems that it can.

Stay tuned for more. In the mean time, here’s another photo of Defense Distributed’s prototype.

Update: Defense Distributed’s political opponents aren’t waiting around for its printable gun to be finished and uploaded before calling for it to be banned. Congressman Steve Israel issued a press release Friday responding to this story: “Security checkpoints, background checks, and gun regulations will do little good if criminals can print plastic firearms at home and bring those firearms through metal detectors with no one the wiser,” his statement reads. “When I started talking about the issue of plastic firearms months ago, I was told the idea of a plastic gun is science-fiction. Now that this technology is proven, we need to act now to extend the ban [on] plastic firearms.”

Why States Still Use Barrel Bombs

Smoke ascends after a Syrian military helicopter allegedly dropped a barrel bomb over the city of Daraya on Jan. 31.(FADI DIRANI/AFP/Getty Images) Summary Barrel bombs are not especially effective weapons. They are often poorly constructed; they fail to detonate more often than other devices constructed for a similar purpose; and their lack of precision means they can have a disproportionate effect on civilian populations. However, combatants continue to use barrel bombs in conflicts, including in recent and ongoing conflicts in Africa and the Middle East, and they are ideally suited to the requirements of resource-poor states. Analysis Barrel bombs are improvised devices that contain explosive filling and shrapnel packed into a container, often in a cylindrical shape such as a barrel. The devices continue to be dropped on towns all over Syria . Indeed, there have been several documented cases of their use in Iraq over the past months, and residents of the city of Mosul, which was re

Russia Looks East for New Oil Markets

Click to Enlarge In the final years of the Soviet Union, Soviet leader Mikhail Gorbachev began orienting his foreign policy toward Asia in response to a rising Japan. Putin has also piloted a much-touted pivot to Asia, coinciding with renewed U.S. interest in the area. A good expression of intent was Russia's hosting of the Asia-Pacific Economic Cooperation summit in 2012 in Vladivostok, near Russia's borders with China and North Korea. Although its efforts in Asia have been limited by more direct interests in Russia's periphery and in Europe, Moscow recently has been able to look more to the east. Part of this renewed interest involves finding new export markets for Russian hydrocarbons. Russia's economy relies on energy exports, particularly crude oil and natural gas exported via pipeline to the West. However, Western Europe is diversifying its energy sources as new supplies come online out of a desire to reduce its dependence on Russian energy supplies . This has

LONDON POLICE INDIRECTLY ENCOURAGE CRIMINALS TO ATTACK RUSSIAN DIPLOMATIC PROPERTY

ILLUSTRATIVE IMAGE A few days ago an unknown perpetrator trespassed on the territory of the Russian Trade Delegation in London, causing damage to the property and the vehicles belonging to the trade delegation , Russian Foreign Ministry Spokeswoman Maria Zakharova said during the September 12 press briefing. The diplomat revealed the response by the London police was discouraging. Police told that the case does not have any prospects and is likely to be closed. This was made despite the fact that the British law enforcement was provided with video surveillance tapes and detailed information shedding light on the incident. By this byehavior, British law inforcements indirectly encourage criminals to continue attacks on Russian diplomatic property in the UK. Zakharova’s statement on “Trespassing on the Russian Trade Mission premises in London” ( source ): During our briefings, we have repeatedly discussed compliance with the Vienna Convention on Diplomatic Relations, specif
