Researchers turn tracking codes into 'clouds' to authenticate genuine 3-D printed parts

A team has found a way to prove the provenance of 3-D printed parts by embedding QR (Quick Response) codes in an innovative way for unique device identification. The researchers describe converting QR codes into 3-D features so that that they neither compromise the part’s integrity nor announce themselves to counterfeiters who have the means to reverse engineer the part.
