Solid Concepts announces the successful creation of the world’s second 3D printed metal gun. Our second iteration is composed entirely of Inconel 625, a material that is stronger than Stainless Steel (and a bit heavier) save for the springs which were not 3D Printed. The gun is once again composed of thirty-four 3D Printed components. Our second gun will be stress relieved and post processing will be by hand once again.
Inconel 625 is a harder, stronger alloy than 17-4 Stainless Steel. We modified the geometry for this second iteration to incorporate different tolerances in order to make hand finishing sufficiently easier. With our first prototype, we had to hand sand to perfect a few tolerances, but our tweaks to the design should remove the need for such sanding. Our first gun is now up to 1,000+ rounds.
We’re thoroughly enjoying this research-development-improvement process for an internal project. The implications of its success for our customers’ future projects – from aerospace to medical – are very uplifting! Thanks to our followers for their support and enthusiasm, it has been quite the ride.
