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.
