The Sigxty Nine is a remarkable 3D printed firearm project that replicates the functionality of the iconic SIG P226, P228, and P229 pistols. Designed by UberPoor over the course of a year with input from the 3D printed firearms community, it represents a major achievement in the world of 3D printed semi-automatic handguns.
At the heart of the Sigxty Nine is a 3D printed frame that incorporates the fire control components like the trigger, hammer, sear, and decocking lever mechanisms. This printed frame integrates with a complete SIG P226/8/9 upper parts kit containing the slide, barrel, recoil spring, and guide rod assembly.
One of the key innovations is the frame’s connected rail design, which helps prevent the common issue of cracked rails on printed frames. The guide also specifies an optimal 30-degree print orientation and settings like 100% infill density to maximize strength and reliability.

The ones they show off in MW3 are not feasible, no. However, there are 3d printed guns that do work, such as this SIG P226 for example pic.twitter.com/4N68LpZDP8
