Band died in the hand of 3D printing pistols?

Former Japanese Prime Minister Shinzo Abe was shot when he made a speech on the streets of Nara on the 8th, dying due to excessive injuries. When the incident broke out, many Chinese media said that "the gunman uses a 3D printing pistol."

"According to the Japanese media" Modern Business "on the 8th, the men's mountains of the former Prime Minister Shinzo Abe have been arrested. His black homemade gun or 3D printer was made."

All kinds of old news about how the 3D printing guns dangerous were immediately turned out and fired.

However, the old driver did not believe in this statement from the beginning. As more and more related investigations were released, it has proved that the murderer has taken a normal homemade double -tube shotgun, which has nothing to do with 3D printing.

Why can the old driver judge this way?

The first thing to figure out is what the so -called 3D printing gun is.

As the materials cited by many media, the earliest 3D printing pistols were the "Liberator" pistol in 2012. It consists of more than 10 parts and components, including gun handles, trigger, gun body and barrel. Printers are printed with common ABS plastic, which is almost impossible to be discovered by safety scanners, and it is more difficult to be tracked, which has attracted great attention from the security departments of various countries.

Since then, the design drawings similar to 3D printing guns have been uploaded to the Internet and spread in large quantities, and warnings about the potential threat of 3D printed guns have been continuously proposed.

However, few people continue to question that this kind of firearm made of hot -plastic ABS plastic materials similar to making Lego bricks, how is the real effect of firing bullets?

As we all know, when the existing guns are basically relying on bullets, the huge pressure generated by the gunpowder explosion promotes the warhead to advance along the barrel at a high speed. This means that the barrel must be able to withstand extremely high pressure. In fact, even the barrel of conventional pistols must be made of special steel to ensure the accuracy and safety during shooting.

The imitation AKS-74U rifle manufactured by the handicraft workshop

It is said that the underground workshop in Pakistan can create a hand -made firearm that is exactly the same as the standard gun, but the only difference is that the latter's barrel quality cannot be guaranteed, and the accuracy of the bullets after a few guns will drop sharply.

This is the case for unqualified metal material gun pipes. Can it be reliable to use ABS plastic to make a barrel of the barrel?

Uh ... the trial results of enthusiastic netizens abroad show that this type of firearm printed with 3D with thermoplastic 3D will basically fires one or two shots and will fall apart due to huge recoil or bore pressure. It is said that when the unlucky Australian police hit a self -made 3D printed gun in the test, the huge recoil of the bullet made the pistol crack instantly at the same time -whether it was hard to say, anyway, it hurt himself ...

Therefore, nowadays, 3D printing pistols that really have effective lethality, among which core components such as barrels, guns and hammers use standard metal gun components, but 3D printing is used in other non -critical parts. In other words, there is no essential difference between this so -called 3D printed gun and the handmade guns in Pakistan's underground workshop.

Of course, there is no higher -level all -metal 3D printed gun. In 2013, Solid Concepts successfully printed a pure metal gun. There are more than 30 components, with stainless steel and chromium nickel iron alloy materials, and have successfully fired 50 rounds. However, the price of 3D printer for making this pistol is relatively expensive, above 500,000 US dollars ...

The topic turned back to Abe's assassination case. The gunman is obviously prepared rather than temporarily, which means that the gun he uses must be carefully selected. As the old driver said before, although the pure plastic 3D printing guns were not difficult to obtain, it was really reliable, and the power of the bullets it fired could not guarantee lethality. Due to Japan's strict gun control measures, it is difficult to get the core components of the pistol, and it is almost the same as obtaining a real gun, which means that the road to "some 3D printing guns" is also unreasonable. As for the all -metal 3D printing pistol ... Come on, it is more difficult to get this high -end 3D printing equipment than real guns.

The gunman is a self -made shotgun at the assassination scene

Therefore, whether it is difficult to obtain the firearms or from the lethality of bullets, the self -control is relatively low, and the powerful shotguns with great power during close shooting have become the ideal choice for the gunner. On -site photos show that his homemade shotgun structure is quite simple, and even uses only tape to fix the gun body, but it adopts a double -tube design to ensure that there can be two opportunities to assassinate. From the on -site video, these careful preparations of the gunmen are carefully prepared by the gunmen. I am afraid that it has played a key role, and Abe fell to the ground when the gunman fired the second shot.

However, the old driver said so much, not to express the meaning of "3D printing guns is not dangerous". In fact, no matter what kind of 3D printed guns, although they have various deficiencies, they have considerable lethality. Especially with the continuous advancement of related technologies, what such an unscractable weapon will evolve in the future is even more worthwhile to be vigilant.
