Beschreibung
Zusammenfassung:	An apparatus and method for manufacturing and authenticating a three-dimensional article including the steps of (1) successively building up the article from a metal powder by an additive manufacturing process by scanning a selected portion of the metal powder with electromagnetic radiation, (2) forming an anti-counterfeiting mark in the article during the additive manufacturing process, and (3) determining whether the article includes the anti-counterfeiting mark.
