New work is emerging in the authentication of parts made using AM. This presentation will detail initial experiments in metals directed energy disposition (or DED) 3D printing, using an innovative anti-counterfeiting solution to protect AM products permanently and invisibly. Chemical fingerprints were strategically and intentionally incorporated in sub-surface layers in a part and then subjected to chemical authentication with a handheld, off-the-shelf detector. The results show promise, but challenges include the selection of compatible materials and characteristics while minimizing the impact on part performance, and appropriate modeling is needed to ensure reliable detection. Chemical tagging and field validation provide a novel security solution for metals AM that can be used in multiple manufacturing environments.
