Engineers have found a way to track 3D-printed guns back to their source Fortunately, researchers at the University at Buffalo, Rutgers University, and Northeastern University have been working on a solution. They’ve created a system, called PrinTracker, which is able to trace 3D-printed objects to their source, based on each 3D printer’s unique fingerprint. They hope that this could help law enforcement and intelligence agencies to track the source […]
