Abstract: A method for removing excess powder from a part for a vehicle during an additive manufacturing process, comprises defining parameters for a part, defining parameters for a removal tool comprising a plurality of links to create a chain-like structure, simultaneously creating the part and the removal tool via additive manufacturing, wherein the part defines an interior passageway and the removal tool is created within the interior passageway and, upon completion of the creation of the part and the removal tool, the removal tool is surrounded by excess powder in the interior passageway, and wherein each link of the plurality of links are created with a gap between adjacent links of the plurality of links, and removing the removal tool from the interior passageway, forcing at least some of the excess powder out of the interior passageway.

Abstract: A system for additive manufacturing a component includes the component configured to be additively manufactured using powder bed fusion. The component includes a first geometry that is different than a second geometry, and the first geometry and the second geometry are configured to create a thermal gradient along the component. The system includes a thermal management structure defined proximate the component. The thermal management structure has a first structure geometry that is different than a second structure geometry. The first structure geometry is defined proximate the first geometry and the second structure geometry is defined proximate the second geometry. The thermal management structure is configured to be additively manufactured with the component substantially simultaneously to reduce the thermal gradient along the component.
