World’s 2nd 3D Printed Metal gun, hot off the sintering machine.

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.

Got a question about the gun? We probably answered it on our Questions Answered blog. Want to see the gun in action? We got that covered too, on our YouTube Channel.

    Out of everything to print, they chose a gun. Faith in humanity now down another notch.

      The 1911 pistol proves to be an excellent technology demonstrator because of its complexity and the extreme forces exerted on it when being fired. Solid Concepts’ goal in making the 3D Printed 1911 public was to deepen the level of conversation around the quality and capabilities of 3D Printing.

      They chose a firearm not because of what it is, but because of what it must endure. Think beyond the terminology. What else in the world takes as much stress on itself as a firearm? By your verbiage, I can only presume that you speak from a position of intolerance and ignorance rather than one of proven knowledge. The amounts of heat and pressure generated with each shot prove the tensile strength of the materials used in a new and exciting way, that is on par or better than current manufacturing methods. Above all else, to improve human thought as well as remove ignorance, is more than a printer can bear (currently). Have a nice day.
