Abstract: A method includes controlling an additive manufacturing system to fabricate a 3D structure using successive layers of material. The additive manufacturing system includes a build platform having a first region, second region, and overlapping third region between the first and second regions; and multiple sources configured to build (e.g., deposit, bond, melt, solidify) the successive layers of material in the regions of the build platform. Controlling the additive manufacturing system includes controlling the additive manufacturing system to build first, second, and third portions of the 3D structure within the regions of the build platform. Each portion of the 3D structure includes (i) one or more test features that are common to the portions of the 3D structure and (ii) a substrate onto or into which the one or more common test features are formed.

Abstract: A method includes forming an initial structure having voids, where the initial structure includes one or more first materials. The method also includes infiltrating one or more second materials into the initial structure, where the one or more second materials are different from the one or more first materials. The method further includes forming a finished structure configured to receive and support one or more heat-generating components. A combination of the first and second materials provides a coefficient of thermal expansion in a portion of the finished structure that substantially matches a coefficient of thermal expansion of the one or more heat-generating components. The finished structure is configured to provide a path to remove thermal energy from the one or more heat-generating components.
