3D printing to create a metal gun
"Three-dimensional concept" company claims that the company has manufactured and tested the world's first metal 3D printing gun. The gun is designed according to the American classic gun Browning 1911 (also known as M1911) and uses "laser sintering technology". "production. The 3D printing specialist who made the gun claimed that the 3D printed gun was “exquisitely treatedâ€, firing 50 rounds of bullets without any jamming, and hit the bullseye multiple times in a distance of about 28 meters.
The body of this 3Dgun is made up of 30 stainless steel parts, an alloy part called Inconel and a nylon handle. The whole gun, in addition to the handle, spring, and other components are produced by "metal laser sintering technology."
The "Stereo Concept" company claims to have the advantage of being finer and with fewer gas holes than those printed by 3D technology and conventionally manufactured gun parts. This print gun, although not comparable in performance to the traditional craft of the gun, but compared to its predecessor - plastic 3D printing gun, both durability and accuracy have surpassed.
2 printing principle?
Selective laser sintering
1. Complete pre-graphic design on the computer
2. Use a high-energy laser to melt small particles of plastic, metal or glass powder into the desired three-dimensional shape.
3. The three-dimensional shape is transformed into a set of slices
4. The sintering machine obtains the required parts by accumulating the pieces one by one.

Parts that break 3D printing are not strong and not accurate
Company manager Firestone revealed that the barrel of this 3D printed gun has to withstand a huge pressure of more than 20,000 psi (pressure unit: about 0.0703 kg per square centimeter) per shot, and the 3D technology they use This gun has withstood the pressure and obtained excellent test results. Connor, the project manager of the "Three-Dimensional Concept" company, said: "What we are doing is to dispel everyone's traditional concept of breaking the view that '3D printing parts are not strong enough or accurate enough for real-world products."
