Abstract: A method of making a component includes: depositing a metallic powder on a workplane; directing a beam from a directed energy source to fuse the powder in a pattern corresponding to a cross-sectional layer of the component; repeating in a cycle the steps of depositing and fusing to build up the component in a layer-by layer fashion; and during the cycle of depositing and melting, using an external heat control apparatus separate from the directed energy source to maintain a predetermined temperature profile of the component, such that the resulting component has a directionally-solidified or single-crystal microstructure.

Abstract: The disclosure relates to an apparatus for manufacturing a metallic component, and corresponding methods. The apparatus may include a build plate with a build surface and an aperture. The apparatus may also include an actuator operable to translate a metallic component such that an end portion of the metallic component is positioned within the aperture of the build plate and below the build surface. The apparatus may further include a seal coupled within the aperture of the build plate and configured to engage the end portion of the metallic component. The aperture of the build plate, the seal, and the end portion of the metallic component may cooperate to form a powder bed to hold metallic powder therein. The apparatus may also include an external heat control mechanism operable to form a predetermined temperature profile of the end portion of the component to prevent cracking of the component.
