Solid Concepts has manufactured the world’s first 3D Printed Metal Gun using a laser sintering process and powdered metals. The gun functions beautifully and has already handled 50 rounds of successful firing. It is composed of 33 17-4 Stainless Steel and Inconel 625 components, and decked with a Selective Laser Sintered (SLS) carbon-fiber filled nylon hand grip. The successful production and functionality of the 3D Printed metal gun proves the viability of 3D Printing for commercial applications.

“We’re proving this is possible, the technology is at a place now where we can manufacture a gun with 3D Metal Printing,” says Kent Firestone, Vice President of Additive Manufacturing at Solid Concepts. “And we’re doing this legally. In fact, as far as we know, we’re the only 3D Printing Service Provider with a Federal Firearms License (FFL). Now, if a qualifying customer needs a unique gun part in five days, we can deliver.”
The metal laser sintering process is one of the most accurate additive manufacturing processes available. The gun proves the tight tolerances laser sintering can meet. Additionally, 3D Printed Metal has less porosity issues than an investment cast part and better complexities than a machined part. When 3D printed gun is fired its barrel sees chamber pressures above 20,000 psi. Solid Concepts chose to build the 1911 because the design is public domain.
“The whole concept of using a laser sintering process to 3D Print a metal gun revolves around proving the reliability, accuracy and usability of metal 3D Printing as functional prototypes and end use products,” says Firestone. “It’s a common misconception that 3D Printing isn’t accurate or strong enough, and we’re working to change people’s perspective.”
3D Printing isn’t just making trinkets as the 3D Printed metal gun proved that. The 3d printed gun debunks the idea that 3D Printing isn’t an effective solution or isn’t ready for mainstream manufacturing. 3D printing is accurate, powerful with the right materials and a company that knows how to best program and maintain their machines.
