Zusammenfassung:	A build substrate for supporting an article during a directed energy deposition (DED) process includes a clad metal layer defining a build surface, where the article is fused to the build surface during deposition. The build substrate also includes a support substrate configured to support stresses and temperatures experienced during deposition. The support substrate defines an upper surface and a lower surface, and at least a portion of the upper surface of the support substrate is covered with the clad metal layer. Un substrat de construction pour supporter un article pendant un processus de dépôt d'énergie dirigée (DED) comprend une couche de métal plaquée définissant une surface de construction, l'article étant fusionné à la surface de construction pendant le dépôt. Le substrat de construction comprend également un substrat de support conçu pour supporter des contraintes et des températures subies pendant le dépôt. Le substrat de support définit une surface supérieure et une surface inférieure, et au moins une partie de la surface supérieure du substrat de support est recouverte de la couche de métal plaquée.
