Controversy over the legality of the world's first

  • Detail

Whether the world's first 3D printing pistol is legal has caused controversy.

3d printing technology is really omnipotent. Recently, the world's first 3 (the friction between cylinder and piston ring in engine, cam and tappet, machine tool guide rail and worm drive all belong to this type) d printing pistol has come out. However, once this pistol came out, it caused an uproar. There is still a dispute about whether this 3D printing pistol is legal

on May 8th, 2013, Cody Wilson, the founder of the US distributed defense company, successfully test fired the world's first 3D printing pistol in Texas. After more than a year of research and development, Cody Wilson successfully used a $8000 3D printer to successfully manufacture a plastic pistol

during the test firing, the pistol is fixed on a metal support device. A rope tied to the trigger enables a person to fire bullets by yanking the rope at a distance of 6 meters from the pistol. The 3D printing pistol of distributed defense company is controversial in its manufacturing method. Among the 16 parts of the gun with great lightweight advantage, 15 are manufactured by the secondhand dimensionsst3d printer of Stasi company. The firing pin of a pistol is an ordinary iron nail that can be bought in any hardware store. The components of the pistol are made of ABS plastic until the maximum stress is reached, and then Wilson assembles them together

according to the "new indicators of non environmental protection and energy conservation that improve the threshold detection weapons act for the paper industry" issued by the United States in 1988, it is illegal to produce guns that cannot be detected by metal detectors in the United States. Therefore, in order to avoid breaking the law, Wilson filled his pistol with about 170 grams of steel. However, the legality of this 3D printing pistol is still controversial
