3D-printed parts are increasingly finding their way into airplanes and operating rooms.
Garter experts predict that, by 2021, 75% of new commercial and military aircraft will feature engine and airframe components made through additive manufacturing.
Similarly, the use of 3D-printed medical implants are set to increase by 20 percent over the next decade.
As the role of additive manufacturing emerges in a variety of industries, engineers will need to verify that their 3D-printed part is genuine and works as designed.
A team at NYU Tandon School of Engineering has found a new way to prove the provenance of a part.
