Cody Wilson – Inventor of 3D Printer Guns Gets Shut Down By Government

3D printing guru Cody Wilson of Defense Distributed announced that the US Office of Defense Trade Controls Compliance, Enforcement Division (DTCC/END) had sent him a letter requesting the group remove all data supposedly in violation of the Arms Export Control Act from public access immediately on his website at http://defcad.org.

The State Department’s Office of Defense Trade Controls (DTCC) have shut down the Austin Texas based 3D printing company.

“I think information will be free, and it wants to be.” Cody said May 9th, 2012 when the State Department’s Office of Defense Trade Controls Compliance (DTCC) Enforcement Division had issued a take down notice to Austin-based 3D gun printing company Defense Distributed declaring the group’s open distribution of 3D gun part files on the Internet potentially violated export laws explicit in the International Traffic in Arms Regulations, or ITAR.

The notice came just days after the group finally managed a fully-functional gun using mainly parts printed from a 3D printer, and aimed to have Defense Distributed take down the offending files and cite their “procedures for determining proper jurisdiction of technical data,” data which, at this point the DTCC says, could be in violation of § 127.1 of the ITAR.

“As an arms manufacturer, we registered ITAR, but we thought since Defense Distributed would be a non-profit software company; we could not have to register for ITAR because we were just a software company and not interested in actual trade of arms, and then number 2, we could basically claim a public domain exemption from the ITAR and we wouldn’t have to ask permission to put the files up for download.”

Gun-related files, Wilson claims, are already regulated and must be permitted before they can be distributed online, but since the beginning, the group has tried to avoid asking government for permission, not to flout the laws, but because they believed they met public domain exemptions.

According to Wilson, the fact that the DTCC cites specific pieces of the ITAR is an indication that they may plan to bring criminal prosecutions of civil penalties against the group.

“So it’s not a good day for the project, but it was expected, and we released, especially the Liberator, in such a good way that it’s definitely online forever and, especially with news of this censorship, I don’t think it will ever disappear. So that’s a success even if Defense Distributed or DefCad is somehow indefinitely shut down.”

Wilson says the group knew what they were up against long before the project even started by studying the case of Phil Zimmermann, the inventor of the Pretty Good Privacy (PGP) encryption program who in 1993 was under investigation by the United States Customs Service.

Similarly, in that case, law enforcement wanted to see if Zimmermann’s software violated federal arms-export laws because the technology could be considered a munition in that, being readily available online, it made it too difficult to determine what kinds of files, transactions and emails were being exchanged and what countries they came from and went to.
As was the case with Zimmermann, Wilson hoped the popularization and widespread distribution of his group’s gun files would lead the State Department to reconsider, if not altogether dump, an investigative effort.

“And to me, I understand that this software seems more closely related to guns so it might be a different case, but the parallels seemed pretty strong. At the end of the day, these are just bits, they’re not actual bombs.”

The frantic rush to regulate the data was no doubt accelerated by Defense Distributed’s recent successes — printable 30-round AR magazines and lower receivers that could withstand more than 650 rounds and of course their latest conquest, the single-shot pistol known as the Liberator.

Additive manufacturing or 3D printing[1] is a process of making a three-dimensional solid object of virtually any shape from a digital model. 3D printing is achieved using an additive process, where successive layers of material are laid down in different shapes.[2] 3D printing is also considered distinct from traditional machining techniques, which mostly rely on the removal of material by methods such as cutting or drilling (subtractive processes).

A materials printer usually performs 3D printing using digital technology. The first working 3D printer was created in 1984 by Chuck Hull of 3D Systems Corp.[3] Since the start of the 21st century there has been a large growth in the sales of these machines, and their price has dropped substantially.[4] According to Wohlers Associates, a consultancy, the market for 3D printers and services was worth $2.2 billion worldwide in 2012, up 29% from 2011.[5]

The 3D printing technology is used for both prototyping and distributed manufacturing with applications in architecture, engineering, construction (AEC), industrial design, automotive, aerospace, military, engineering, civil engineering, dental and medical industries, biotech (human tissue replacement), fashion, footwear, jewelry, eyewear, education, geographic information systems, food, and many other fields. It has been speculated[6] that 3D printing may become a mass market item because open source 3D printing can easily offset their capital costs by enabling consumers to avoid costs associated with purchasing common household objects

Artificial blood vessels made on a 3D printer may soon be used for transplants of lab-created organs.
Until now, the stumbling block in tissue engineering has been supplying artificial tissue with nutrients that have to arrive via capillary vessels.
A team at the Fraunhofer Institute in Germany has solved that problem using 3D printing and a technique called multiphoton polymerisation.
The findings will be shown at the Biotechnica Fair in Germany in October.
Out of thousands of patients in desperate need of an organ transplant there are inevitably some who do not get it in time.
In Germany, for instance, more than 11,000 people have been put on an organ transplant waiting list in 2011 alone.
To make sure more patients receive these life-saving surgeries, researchers in tissue engineering all over the globe have been working on creating artificial tissue and even entire organs in the lab.
But for a lab-made organ to function, it needs to be equipped with artificial blood vessels – tiny and extremely complex tubes that our organs naturally possess, used to carry nutrients.

Dr Gunter TovarFraunhofer Institute, Germany

Numerous attempts have been made to create synthetic capillaries, and the latest one by the German team seems to be especially promising.
“The individual techniques are already functioning and they are presently working in the test phase; the prototype for the combined system is being built,” said Dr Gunter Tovar, who heads the BioRap project at Fraunhofer Institute for Interfacial Engineering and Biotechnology IGB in Stuttgart.

Elastic biomaterials

3D printing technology has been increasingly used in numerous industries, ranging from creating clothes, architectural models and even chocolate treats.
But this time, Dr Tovar’s team had a much more challenging printing mission.
To print something as small and complex as a blood vessel, the scientists combined the 3D printing technology with two-photon polymerisation – shining intense laser beams onto the material to stimulate the molecules in a very small focus point.
The material then becomes an elastic solid, allowing the researchers to create highly precise and elastic structures that would be able to interact with a human body’s natural tissue.
So that the synthetic tubes do not get rejected by the living organism, their walls are coated with modified biomoelcules.
Such biomolecules are also present in the composition of the “inks” used for the blood vessel printer, combined with synthetic polymers.
“We are establishing a basis for applying rapid prototyping to elastic and organic biomaterials,” said Dr Tovar.
“The vascular systems illustrate very dramatically what opportunities this technology has to offer, but that’s definitely not the only thing possible.”
