Abstract: An additive manufacturing (AM) apparatus is provided, having a build unit including a powder delivery mechanism, a powder recoating mechanism, and an irradiation beam directing mechanism. The AM apparatus further includes a rotatable build platform having an inner diameter and an outer diameter. A fluid flow mechanism includes an inlet body forming an inlet plenum and a collector body extended from the inlet body. The collector body forms a collector plenum in fluid communication with the inlet plenum. The collector body forms an outlet opening, wherein the outlet opening is positioned proximate to the inner diameter of the rotatable build platform. The outlet opening is configured to provide a flow of fluid toward the outer diameter above the rotatable build platform.

Abstract: Methods and systems for fabricating a component by consolidating a particulate include a build platform configured to receive the particulate, a particulate dispenser configured to deposit the particulate onto the build platform, and a consolidation device configured to consolidate at least a portion of the particulate to form a component. The methods and systems also include a first actuator assembly configured to induce rotation of the build platform about a rotation axis at a first speed. The rotation axis extends through a center of the build platform. The methods and systems further include a second actuator assembly including an actuator and a shaft extending along the rotation axis. The actuator is configured to cause rotation of the shaft about the rotation axis at a second speed different from the first speed. The shaft is coupled to the build platform and configured to induce linear movement of the build platform along the rotation axis upon rotation of the shaft.

Abstract: A recoating device for an additive manufacturing system includes a plurality of recoater blades which include a first stage and a second stage. The first stage includes a plurality of rows of the plurality of recoater blades and extends in the transverse dimension. The second stage includes a plurality of recoater blades and is configured substantially similar to the first stage of the plurality of recoater blades. The second stage of recoater blades is displaced from the first stage of recoater blades in the vertical dimension.
