A U.S. company recently released an ad that says it would take just a few hours to make a semi-automatic gun with a computer and a 3D printer, click print, and go away. No production license, no age limit, no background check, no need for a firearm serial number or a sales receipt requiring tracking of firearms. Having a gun easily at home without knowledge of gun and gun technology.
Since the end of last year, U.S. President Saddam Hood Primary School shot dead in the United States, U.S. President Barack Obama is vigorously pushing gun control. However, the development of science and technology continues to pose new challenges to U.S. gun control.
Printing guns is easy
These 3D printers, which cost about $ 1,000, can print objects of various shapes by spraying thin plastic, metal or ceramic coatings. This type of printer has long been used by industrial companies to make prototypes and components. Some amateurs have already printed fairly simple objects: prostheses, iPhone cases, cat sculptures and missing luggage loops. However, some people have already used 3D printers to make firearm parts, and guns made with these parts have successfully fired bullets.
3D printing gun This technology was invented by a radical U.S. organization called Defense Distributed, who have created downloadable drawings that can be downloaded online and then passed through a 3D printer AR-15 gun body print out, and then create AR-15 semi-automatic gun.
The organization's founder, Texas State University law student Cody Wilson called the gun a wikis weapon: "The great thing about the Vikings weapon is that it only needs a fatal blow, and that's the philosophy behind it. The fact is that it did And even if it's only once deadly, we've come to that threshold and we'll have a weapon system that can be printed on the desktop, and with the computer, we can make weapons. "
Wilson mentioned a project in the video: the RepRap printer, which will replicate itself through other 3D printers. After criminals have used their printed weapons to commit crimes, they can melt the plastic and reprint it into a mundane statue of Buddha. Firearms made of plastic can not be identified by metal detectors at airports, courts or other government agencies.
Currently Distributed Defense has 3D printed drawings of two plastic guns, one of which is a training gun with no moving parts, an electromagnetic firing bullet and the other with moving parts that are closer to a real gun .
It is understood that the researchers had originally planned to print and test the prototype of the firearm without a license, but after being exposed by the media, the project had to be suspended pending the release of a license from the United States Government to manufacture a firearms legally. Wilson said: "If we think the information should be free, then the Internet is the last barrier between freedom, knowledge and society, since we can share all the information, then the firearms manufacturing information is not it?" The company has Released on the website of multiple gun parts 3D printed drawings for users to download for free.
Print gun easy to use?
Some gun experts have challenged the technology to guess whether the plastic components of this 3D printer can withstand the pressure of a firearm fire, including the force that explodes and ejects each bullet. On December 1, 2012, a technician tested the 3D printing gun. During the initial test shot, the AR-15 submachine gun manufactured by the 3D printer did not have any problems, but at the sixth shooting, three firearms appeared Fragmentation, serious damage after loading bullets. There are also firearms enthusiasts who mount 3D-printed magazines on real guns, often involving shotgun shells during shooting tests. Therefore, it is expected that 3D-printed guns will have the same quality as guns made in the normal process, and I am afraid that the current technology is still very difficult to achieve.
Michael Guslik, an amateur gun manager who has exclusively released a number of 3D printing gun production technologies online, said people have been experimenting with homemade firearms for some time now. He said the best-known example is a zip gun made of water pipe parts (not surprisingly, production drawings and tutorials can be downloaded online). "It's just about applying different technologies to what's already being done, but 3D-printed guns are harder to produce than water-pipe guns." To date, this task is not as simple as printing, though some have been successful 3D printing gun. The main issue is not print technology, but the lack of a tough enough plastic to make firearms. But in 2012 Gusick printed some of the AR-15 semi-automatic rifle parts on a 3D printer using ABS plastic, the same plastic used to make LEGO toys. With regard to printed materials, currently only limited to thermosetting plastics for low-end printers, very high-end printers can be printed using ceramics and metals. General printer resolution of 0.1 mm.
Opponents are worried about the proliferation of firearms
Copying deadly weapons through 3D printing shocked the U.S. anti-firearm community. Many Americans worry that this is not a question of freedom, which is related to public and personal security. Still others fear that such printed plastic guns will run past metal detectors and pose a greater risk to national security. Leah Barrett, a member of the New York-based anti-firearms violent group, is worried about the potential firearms rampant. "Using 3D technology to print plastic guns is daunting and worrying. Imagine now that 40% of Americans buy guns All attempt to evade background checks, and those who print plastic firearms at home are more likely to conduct background checks on them. In addition, these firearms may fall into criminals, those with severe mental illnesses, those with serious domestic violence, and even Is the hands of children and other people should not have guns. "
The shooting at the Connecticut campus triggered the U.S. government's further management of firearms, and the 3D gun-printing technology was born just shortly after the shooting in Connecticut and made the government gunless. The American people's debate over gun management is even more talkative. One New York City resident said he was scared to face a strike wherever he went.
"Even if you stand here, someone who crosses the street may have a 3D printing gun and he might shoot to test whether the gun works or not." That's scary.
