Abstract: 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.

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.

Abstract: A printing assembly for an additive manufacturing apparatus includes an energy emitter configured to steer one or more emissions across a build platform to raise a temperature of a build material on the build platform from an initial temperature to a first temperature, the first temperature being less than a threshold temperature set by material dependent metallurgical properties, and a fusing beam emitter configured to generate one or more laser beams to raise the temperature of the build material on the build platform from the first temperature to a second temperature, the second temperature being greater than the threshold temperature.

Abstract: Disclosed herein are print heads for an additive manufacturing apparatus. The print heads include a housing. A projection element is disposed within the housing and is configured to receive the one or more laser beams generated by a beam emitter and project a plurality of projected laser beams in a pattern. A consolidating optic is disposed within the housing and is located below the projection element. The consolidating optic is configured to consolidate the pattern of the plurality of projected laser beams into a consolidated pattern of projected laser beams.
