In the field of 3D printing , I am afraid that no topic is more controversial than 3D printing guns. This topic began in 2013 when the US Distributed Defense organization and its founder Cody Wilson published their 3D printed pistol design drawings online for free, sparking global attention and the vigilance of governments. Cody Wilson closed the download of the design despite the ban imposed by the US State Department. However, Wilson has always believed that 3D printing design is a kind of freedom of speech and should not be censored. He even sued the US State Department and some officials for unconstitutionality, and the US government has launched a lawsuit. Recently, he even got some Republican lawmakers. The support made the situation complicated.
In other countries outside the United States, the fear that 3D printing weapons may be used by terrorists and criminals has never stopped. Especially after the terrorist attacks in Paris. In general, most of the world's governments (including China) and public opinion support the prohibition of the spread of 3D printed weapons design.
But in this process, the distributed defense organization that has always insisted on the rights of 3D printing guns is not idle. They are busy developing an automatic weapon for 3D printing, the AR-15 semi-automatic rifle, and plan to announce its latest design in April 2016. "I assure you that you haven't seen it now because it was delayed because of man-made reasons. If I were allowed to do so, I would show it in front of you." 27-year-old Cody Wilson The British "Mirror" said: "We are fighting the government, and now we have a whole new set of things." When it was explicitly asked whether this meant that a new 3D printer gun was coming, he confirmed this.
Wilson further added that all you need is a 3D printer and a few parts that you can buy from a hardware store – such as a striker. "We still can't print bullets or strike pins in 3D, because the compactness of the material is not enough. So we just recommend using something that is common on the market," he said.
The Mirror, which has long been known for its sympathetic left, is now questioning that such 3D printing guns may be used by terrorist organizations like the Islamic State (IS) because the metal parts used in such 3D printing guns are very Less, it is difficult to detect by security equipment, and the manufacturing cost is very low (less than £100), which poses a considerable security risk. But when asked if he was concerned that his guns would be used in a terrorist attack, Wilson's reaction was negative. "This is not true. There are actually a variety of books on how to make bombs in the library. All we want is a guarantee of free exchange of ideas," he said.
But Wilson's behavior has caused strong condemnation by British anti-terrorism experts. The Mirror quoted former intelligence official Hamish de Bretton Gordon as saying that Wilson’s efforts made the work of terrorists easier. "Especially in the UK, security agencies are putting so much effort to prevent IS attacks," he said. "The person who released these (3D printing weapons design) is completely irresponsible. We can only hope that the US authorities will handle this person quickly. This is absolutely crazy." He further added: "This behavior will force the government." Start tracking sales of 3D printers."
