A thermal control apparatus including a body defining a centerline axis extended along a height and a circumferential direction extended relative to the centerline axis. The body forms a flow circuit therethrough, an inlet opening, and an outlet opening each in fluid communication with the flow circuit. The flow circuit is extended in parallel flow arrangement along the circumferential direction from the inlet opening to the outlet opening. A cavity is extended at least partially through the body along the centerline axis. A thermal control system includes the thermal control apparatus, a fluid flow device configured to provide a flow of heat transfer fluid to the apparatus through the inlet opening and to receive the flow of heat transfer fluid from the outlet opening of the apparatus, and a flow conduit providing fluid communication of the flow of heat transfer fluid between the fluid flow device and the apparatus.

A recoater for an additive manufacturing apparatus includes a recoater arm and retainer operably coupled with the recoater arm. The retainer includes a housing defining a cavity. A blade carrier supports one or more blades. An actuator is operably coupled with the housing and is configured to compressively retain an upper portion of the blade carrier within the cavity between a slide of the actuator and the housing.

Recoater for additive manufacturing

An irradiation device for additively manufacturing three-dimensional objects may include a beam generation device configured to generate an energy beam, an optical modulator including a micromirror array disposed downstream from the beam generation device, and a focusing lens assembly disposed downstream from the optical modulator. The micromirror array may include a plurality of micromirror elements configured to reflect a corresponding plurality of beam segment of the energy beam along a beam path incident upon the focusing lens assembly. The focusing lens assembly may include one or more lenses configured to focus the plurality of beam segments such that for respective ones of a plurality of modulation groups including a subset of micromirror elements, a corresponding subset of beam segments are focused to at least partially overlap with one another at a combination zone corresponding to the respective modulation group.
