It’s here, a full metal 3D printed firearm. TheFirearmBlog posted about the first fully metal 1911. Solid Concepts created their 1911 clone with a 3D laser metal sintering printer. Unlike others making 3D firearms Solid Concepts has an FFL manufacturing license and can print a firearm for their customers within a day.
Laser sintering is one of the most accurate manufacturing processes available, and more than accurate enough to build the 3D Metal Printed interchangeable and interfacing parts within our 1911 series gun. The gun proves laser sintering can meet tight tolerances. 3D Metal Printing has less porosity issues than an investment cast part and better complexities than a machined part. The barrel sees chamber pressure above 20,000 psi every time the gun is fired. “We’re proving this is possible, the technology is at a place now where we can manufacture a gun with 3D Printing,” says Firestone. “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.”
I mentioned earlier this isn’t about desktop printers, and it’s not. The industrial printer we used costs more than my college tuition (and I went to a private university) and the engineers who run our machines are top of the line; they are experts who know what they’re doing and understand 3D Printing better than anyone in this business. Thanks to them, Solid Concepts is debunking the idea that 3D Printing isn’t a viable solution or isn’t ready for mainstream manufacturing. We have the right materials, and the right engineers who know how to best program and maintain these machines, to make 3D Printing accurate, powerful and here to stay.
