Since the production of the world's first 3D printing pistol was published online last week, people are worried about the security threats it may pose. This worry is obviously not a worry. On the 10th, two reporters from the Sunday Post hid a 3D printed pistol in their clothes and successfully passed the security check at St. Pancras Railway Station in London. The "European Star" train to Paris, France.
36 hours, 16,000 yuan
The world's first pistol "liberator" made with 3D printing technology was developed by Cody Wilson, a 25-year-old American college student. The 16 components of the Liberator are made of plastic, the only exception being the pistol striker. Two reporters from the Sunday Post downloaded the design of the 3D printing pistol "Liberator" from the Internet and purchased a 3D printer worth £1,700 (about RMB 16,000) from the Internet.
Subsequently, the two reporters used the printer and printed the 16 parts required for the pistol in plastic in just 36 hours. Then, according to the instructions of the design drawings, the two reporters quickly installed these parts into a plastic pistol that was able to launch small-caliber bullets and was fatal enough.
Airport security check
At 5 o'clock on the afternoon of the 10th, two reporters took the 3D pistol and arrived at St. Pancras International Railway Station in London during the peak traffic period. They planned to use it to check the security inspection procedures of the train station, which is called "as strict as the airport". . The reporter split the pistol into three parts, which were hidden in the clothes. When passing through the metal detector, since all parts of the pistol are made of plastic, the bell is not touched at all. In this way, the reporter successfully passed the security check, and God unconsciously took the 3D printing pistol to the "European Star" train to Paris, France.
When the "European Star" train started, the reporter took out the hidden accessories and assembled the pistols in an imposing manner. In just 30 seconds, they successfully assembled the various parts of the gun. What makes people stunned is that the reporter even stood in the carriage, standing next to other passengers, showing off the 3D printing pistol and taking a few photos, but it was not blocked by anyone.
The two undercover reporters did not bring the bullet and the only metal part of the pistol, the striker, to the train. Despite this, two reporters pointed out that because the small metal parts of the striker can be bought at any hardware store, and these tiny metal objects can be easily hidden, it is not a crime if criminals really want to bring them to the train. Difficult.
Former British Labor and Social Security Minister Rod West said that the reporter’s “experiment†showed that the 3D printing pistol was “extremely dangerous†because it was difficult to detect by security equipment.
US Congressman Isriel pointed out: "Criminal elements can print plastic guns at home and carry firearms through metal detectors. The safety checkpoints and gun management regulations will be ineffective!"
3D printing is fast manufacturing, no need for molds, direct sample prototyping. The printed materials are rubber, plastic, metal, etc. Some people have produced Jewelry , toys, tools, kitchen supplies, etc. Even car experts have printed out auto parts, and various bones may be printed for clinical use in the future.
Compared to the traditional large factory manufacturing model, there are many steps between drawing and physical. Anything that is complex in shape can be broken down into a series of two-dimensionally fabricated overlays. The equipment that makes the world's first 3D printing gun is about 8,000 US dollars (about 49,000 yuan), not a high price. The price of the 3D printer mentioned above is only £1,700 (about 16,000 yuan). Taking a flashlight as an example, a 3D printer can scan a flashlight through a computer to create a three-dimensional design. Then, the three-dimensional prototype is “sliced†and divided into layers. After that, the printer will follow the design layer. The layer was “sprayed†until a flashlight was finally produced, but the 3D printer sprinkled not the toner, but the melted resin, metal or ceramic.
1. Apply computer software to design a three-dimensional processing style;
2. Transfer the style information to the 3D printer, and then deposit and bond the liquefied, silked and powdered solid materials with special glue;
3. Solid object product printing and molding.

Design drawings download over 100,000 US government emergency stop
New Express News Due to concerns about the proliferation of 3D printing pistols, the US government recently issued a ban on a free downloadable 3D pistol design released online by a non-governmental organization.
According to US media reports, Cody Wilson, the founder of the non-profit organization "Defense Distribution," was released online this month. The design download is completely free and can be downloaded by anyone. This pistol is called "The Liberator" and consists of 16 parts. The material used in the 3D printer is also a strong, heat-resistant plastic. The gun, which was first printed with 3D technology, was successfully tested on the 4th of this month.
"Defense Distribution" issued a statement on the website stating that, in accordance with the requirements of the US Department of Defense's head of the arms trade department, the public download channel has been closed and the 3D print gun design has been removed. However, this design has been downloaded more than 100,000 times before the US government stopped.
Cody Wilson emphasized that he followed the current law in preparation and implementation of the plan, and he believed that the Department of Defense's requirements were more politically motivated.

To be technical or to be safe
Technology itself does not care whether the things it creates are beneficial or harmful to human society. As for how to use the norms to constrain the double-sidedness of technology, it is the eternal topic of human beings, from the nitroglycerin detonator in 1862 to the last century. Nuclear technology, as well as the emergence of 3D printing guns.
This has caused people's extreme concern that 3D printers can easily enter any home (currently just a cost issue), if criminals print out all-plastic guns at home, and can unimpededly detect metal through various levels of sea, land and air. Instrumentation, all security checks, background checks, and gun laws in today's society will be in vain. A large number of weapons of mass destruction flow into the “unmanageable, undetectable†situation. While the speed, scale and compatible materials of 3D printers are changing with the day, we don't want to find out in the future that the neighbors are in his garage to drum up something you only saw in the war documentary. In other words, 3D printing guns are just the beginning.
Currently in the United States, the most important clause that governs the production and circulation of 3D printing guns is the decades-long Undetectable Guns Act. In order to comply with this rule, one of the non-functional parts of the Cody Wilson test fire was made of metal and the only non-printed part, so that the pistol could be detected.
3D printing technology is widely used as a complementary production tool in people's minds – providing some plastic parts for large manufacturers and “alternatives†for human bones and even tissues and organs for the medical industry; there are some low-end 3Ds. The printer can enter the personal consumption field, so that we can print the screws on the net head or the temporary strike on the stool at home.
But what we can't control is that with the technology's higher precision and the ability to select materials over a wider range, 3D printers are used directly as production tools, such as printing a whole car or a rifle. In particular, the latter involves social issues that cannot be ignored.
The fluctuations caused by this 3D printing gun may only be a microcosm of the entanglement between technology and norms in the third industrial revolution.
