Abstract: This disclosure provides systems and tooling for cooling components during additive manufacturing. A build plate supports layers of powdered materials as they are positioned and selectively fused to create the component. The build plate defines a build surface and the build surface retracts in a working direction opposite a build direction for the component. At least one vertical cooling structure is provided perpendicular to the build plate and protruding from the build plate as the build surface retracts. The vertical cooling structure cools at least a portion of the component through unfused powdered materials between the vertical cooling structure and the component.

Abstract: A hot gas path component includes a substrate having an outer surface and an inner surface. The inner surface defines an interior space. The outer surface defines a pressure side surface and a suction side surface. The pressure and suction side surfaces are joined together at a leading edge and at a trailing edge. A first cooling passage is formed in the suction side surface of the substrate. It is coupled in flow communication to the interior space. A second cooling passage, separate from the first cooling passage, is formed in the pressure side surface. The second cooling passage is coupled in flow communication to the interior space. A cover is disposed over at least a portion of the first and second cooling passages. The interior space channels a cooling fluid to the first and second cooling passages, which channel the cooling fluid therethrough to remove heat from the component.
