… Developed by scientists at New York University's Tandon School of Engineering, the system instructs manufacturers' 3D printers to include hundreds of tiny elements within objects, as they're being printed. … "By converting a relatively simple two-dimensional tag into a complex 3D feature comprising hundreds of tiny elements dispersed within the printed component, we are able to create many 'false faces,' which lets us hide the correct QR code from anyone who doesn't know where to look," says associate professor Nikhil Gupta, leader of the study.
