Researchers from the NYU Tandon School of Engineering have developed a method for proving where 3D printed parts come from and ensuring their design integrity by embedding QR code clouds into the 3D model in a new and clever way. That is, rather than simply sticking a QR bar code onto the 3D model’s surface, the research team has devised a way to convert QR codes into subtle 3D features which can be integrated into a given part without affecting its properties and, crucially, without being noticeable to counterfeiters.
