Abstract: A splatter shield system for an additive manufacturing machine includes one or more splatter shields configured to cover at least a portion of a build area during energy application such that the at least one splatter shield is positioned between an energy source of an additive manufacturing machine and the build area during energy application. The one or more splatter shields are transparent to an energy source (e.g., a laser) of the additive manufacturing system such that energy application occurs through the splatter shield.

Abstract: A system and method are disclosed for additively manufacturing a component that includes placing a primary insert and a first support insert into corresponding indentations in a build plate of an additive manufacturing system, forming the component on the primary insert with the component having at least one overhang located above the first support insert, and forming a first support structure on the first support insert so as to be beneath the at least one overhang with the first support structure configured to support the at least one overhang. The method also includes, after the component has been formed, separating the primary insert from the first support insert such that the first support structure is separated from the component.

Abstract: A shrouded rotor constructed through a hybrid additive manufacturing process. The shrouded rotor including a hub at a radial center having an outer surface forming an inner wall of a flow path, a shroud at a radial outer side having an inner surface forming an outer wall of the flow path, and vanes extending within the flow path between the hub and the shroud. The outer surface of the hub, the inner surface of the shroud, and all surfaces of the vanes have a surface roughness average of less than 32Ra.

Abstract: A hybrid additive manufacturing process is utilized for creating a shrouded rotor with the shrouded rotor having a hub at a radial center, a shroud at a radial outer side, and vanes extending therebetween. The hybrid additive manufacturing process includes forming the shrouded rotor in stages, with a first stage being formed by depositing material in an axial direction through a first stage of the hub, machining an outer surface of the first stage of the hub to smooth the outer surface, depositing material on the first stage of the hub in a radial direction through a first stage of the vanes and the shroud, and machining all surfaces of the first stage of the vanes and an inner surface of the first stage of the shroud to smooth the surfaces. Subsequent stages of the shrouded rotor are formed similarly to the first stage.

Abstract: A method of cleaning a recoater of an additive manufacturing machine includes installing a cleaning fixture into the additive manufacturing machine, the cleaning fixture including one or more cleaning elements, advancing the recoater into contact with the one or more cleaning elements, and rotating the recoater about a recoater axis thus dislodging material from a recoater outer surface due to frictional contact with the one or more cleaning elements.
