Abstract

See full text

A build unit for additively manufacturing three-dimensional objects may include an energy beam system having one or more irradiation devices respectively configured to direct one or more energy beams onto a region of a powder bed, and an inertization system including an irradiation chamber defining an irradiation plenum, one or more supply manifolds, and a return manifold. The one or more supply manifolds may include a downflow manifold configured to provide a downward flow of a process gas through at least a portion of the irradiation plenum, and/or a crossflow manifold configured to provide a lateral flow of the process gas through at least a portion of the irradiation plenum. The return manifold may evacuate process gas from the irradiation plenum. While irradiating the region of the powder bed, the process gas may flow through the one or more supply manifolds, into the irradiation plenum, and into the return manifold.
