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. Un appareil et une méthode de fabrication et dauthentification dun article tridimensionnel comprend les étapes suivantes : (1) former progressivement larticle à partir dune poudre métallique au moyen dun procédé de fabrication additive en balayant une partie sélectionnée de poudre métallique au moyen dun rayonnement électromagnétique; (2) former une marque anti-contrefaçon dans larticle pendant le procédé de fabrication additive; (3) déterminer si larticle comprend la marque anti-contrefaçon.
