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.

Abstract: A method for assessment of operational performance of a 3D manufacturing apparatus is provided. Images are obtained, in real-time during a 3D polymer printing build process in which at least one structure is built by the 3D manufacturing apparatus, the images being of an area of a build platform on which the at least one structure is built. The obtained images are evaluating, and it is determined, based on the evaluating, whether an operational flaw with the 3D manufacturing apparatus has occurred. Operational flaws include errors in the operation of the 3D manufacturing apparatus and/or component thereof, as evidenced by, for instance, distortions or other errors in the structure(s) being built and/or materials being used.

Abstract: A method of creating an article of manufacture is provided, which includes directing multiple laser beams to a single galvanometer; and dynamically repositioning the multiple laser beams in counterpart paths using the single galvanometer to shine the multiple laser beams on and melt a first powder material and, upon solidification of the melted first powder material, forming a first series of duplicate three dimensional structures, where each of the multiple laser beams is used to form at least one of the first series of duplicate three dimensional structures.

Abstract: Assessment of operational performance of an additive manufacturing apparatus is provided. Particle size images are obtained, in real-time during an additive manufacturing build process in which at least one structure is built by the additive manufacturing apparatus, the obtained images being of an area of a build platform on which the at least one structure is built. The obtained images are evaluated, and it is determined, based on the evaluating, whether an operational flaw has occurred with the additive manufacturing apparatus or a design for the at least one structure. Operational flaws include errors in the operation of the additive manufacturing apparatus and/or component thereof, as evidenced by, for instance, distortions or other errors in the structure(s) being built and/or materials being used.
