Abstract
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.
Claims20
A build substrate for supporting an article during a directed energy deposition (DED) process, the build substrate comprising:
- a clad metal layer defining the build surface, wherein the article is fused to the build surface during deposition;
- and
- a support substrate configured to support stresses and temperatures experienced during deposition, wherein 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.
A method of creating an article by a DED process, the method comprising:
- depositing a build material by a nozzle upon a build substrate, wherein the build substrate supports the article during the DED process;
- and
- fusing the article to a build surface, wherein the build surface is defined by a clad metal layer, and wherein the build substrate further includes a support substrate configured to support stresses and temperatures experienced during deposition, wherein 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.
