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.
