IRRADIATION REGIMES FOR ADDITIVE MANUFACTURING MACHINES

Abstract:

A method of additively manufacturing three-dimensional objects may include determining an irradiation regime for a plurality of object elements of a layer of an object to be additively manufactured, and forming the plurality of object elements at least in part by irradiating a layer of a build plane with one or more irradiation devices of the additive manufacturing machine. The plurality of object elements may include a core region and a shell region. The shell region may at least partially surround the core region. The irradiation regime for at least one of the plurality of object elements may include a core-shell irradiation regime. Additionally, or in the alternative, the irradiation regime for at least one of the plurality of object elements may include a core-shell apportioned irradiation regime.
