Security researchers identify "fingerprints" in 3D printed objects that can be used to trace their manufacturing

In PrinTracker: Fingerprinting 3D Printers using Commodity Scanners (Scihub mirror), a paper to be presented at the ACM SIGSAC Conference on Computer and Communications Security conference in Toronto this month, a group of U Buffalo and Northeastern researchers present a model for uniquely identifying which 3D printer produced a given manufactured object, which may allow for forensic investigators to associate counterfeit goods, illegal guns, and other printed objects with the device that manufactured them.
