    Abstract: 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.

    Abstract: An additive manufacturing machine (900) including a build unit (904) that is supported by an overhead gantry (912) and a method for positioning the build unit (904) are provided. A positioning system (930) includes one or more position sensors (932) that are separate from the build unit (904) and are configured for obtaining positional data of the build unit (904). The positioning system (930) may continuously track the position and orientation of the build unit (904) and the additive manufacturing machine (900) may adjust the position of the build unit (904) toward a target position.

    Abstract: An irradiation device for additively manufacturing a three-dimensional object includes two beam generation devices emitting energy beams that are characteristically different than one another. An optical modulator includes a micromirror array disposed downstream from the first and second beam generation devices. A focusing lens assembly is disposed downstream from the optical modulator. The micromirror array includes a plurality of micromirror elements to reflect beam segments corresponding to the first and second energy beams incident upon the focusing lens assembly. The focusing lens assembly focuses a first portion of the beam segments corresponding to the first energy beam to at least partially overlap with one another at a first one of a plurality of combination zones and focuses a second portion of the beam segments corresponding to the second energy beam to at least partially overlap with each other at a second one of a plurality of combination zones.

    Abstract: An additive manufacturing system may include an irradiation device configured to emit an energy beam having a manufacturing power level selected to additively manufacturing a three-dimensional object by irradiating a powder material, and a controller configured to perform one or more beam alignment operations when irradiating the powder material. The irradiation device may include a beam source, one or more beam positioning elements, a beam splitter configured to split a measurement beam from the energy beam, and one or more beam sensors configured to determine one or more parameters of the measurement beam. The one or more beam alignment operations may include determining position information of the energy beam based on the one or more parameters of the measurement beam, and aligning the energy beam with an optical axis of the irradiation device by adjusting a position of the one or more beam positioning elements based on the position information.

    Abstract: 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.
