Digital Engineering 247 covered UB research by Wenyao Xu on traceability of 3D printed objects. The study, in collaboration with colleagues at Rutgers University and Northeastern University, details the PrinTracker solution, which essentially can detect a unique “fingerprint” of a printer to aid in traceability.
“Think about the 3D printing process as analogous to people’s handwriting,” explains Wenyao Xu, associate professor of computer science and engineering.
“Different machines are going to fabricate the same product differently because of their own hardware properties and manufacturing processes. Each machine leaves a unique signature on the product.”
