摘要： 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.

摘要： A computer-implemented method for generating a manufacturing dataset having cloned geometric features for an additive manufacturing process includes identifying, via a processor, a repeating design feature in a first manufacturing dataset that defines a three-dimensional workpiece. The method further includes determining, via the processor, a processing cost or benefit for cloning the repeating design feature, and generating, via the processor, a second dataset having with repeating design feature isolated responsive to the determined processing benefit. The method includes generating, via the processor, a third dataset from the first manufacturing dataset. The third dataset that replaces the repeating design feature with a reference to the second dataset having the repeating design feature.

摘要： A method of making an article is disclosed in which a fusible material is fused with an energy beam applied to the fusible material at a build location with a scanning pattern comprising a plurality of parallel lines terminating at the contoured edge. An energy beam is also applied with a vector scanning pattern at the build location along the contoured edge to liquefy and re-solidify material at the build location along the contoured edge. The method also includes controlling vector scanning energy beam intensity, vector scanning energy beam scanning speed, vector scanning energy beam focus depth, or any combination thereof as a function of an angle between the plurality of parallel lines and the vector along the contoured edge.

摘要： An example method of making a component includes providing a digital model of a component to a software program, the software program operable to slice the digital model into digital layers and raster each digital layer into digital segments, the digital segments delineated by digital raster lines. The method further includes depositing a first layer of powdered material onto a platform, compacting the first layer of powered material into a first compacted layer, sintering the first compacted layer along lines corresponding to the digital raster lines using a laser, wherein the laser operates at a first power and a first scan speed, and sintering the first compacted layer along a perimeter of the first compacted layer using the laser to form a first unitary layer, wherein the laser operates at a second power and a second scan speed, wherein the ratio of the first power to the second power is less than about 3. An apparatus for making a component is also disclosed.

摘要： A method includes issuing a state change fluid into an internal passage of an additively manufactured article and causing the state change fluid to change from a first state having a first viscosity to a second state that is either solid or has a second viscosity that is higher than the first viscosity within the internal passage. The method can also include causing the state change fluid to change back from the second state to the first state and flushing the state change fluid from the internal passage to remove residual powder from the additively manufactured article.

摘要： 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.
