Feasibility in metals has been demonstrated for a fast, accurate method for authenticating three-dimensional printed products. The method relies on spectral signatures produced from chemical taggants, yielding covert material-based fingerprinting. Fingerprints were created using a directed energy deposition multimaterial additive manufacturing system, and detected with x-ray fluorescence spectroscopy.
