Apparatus for additively manufacturing three-dimensional objects by means of successive layerwise selective irradiation and consolidation of layers of a build material which can be consolidated by means of an energy beam, comprising an irradiation device is adapted to generate the energy beam and guide the energy beam over a determination plane, in particular a build plane in which the build material is applied to be irradiated, wherein the irradiation device is adapted to generate at least one irradiation region, in particular a melt pool, in the determination plane, wherein a determination device is provided that is adapted to determine a focal position of the energy beam and/or a difference between a reference focal position and an actual focal position of the energy beam based on radiation that is emitted from at least one irradiation region.
Apparatus (1) for additively manufacturing three-dimensional objects (2) by means of successive layerwise selective irradiation and consolidation of layers of a build material (3) which can be consolidated by means of an energy beam (5), comprising an irradiation device (4) that is adapted to generate the energy beam (5) and guide the energy beam (5) over a determination plane (6), in particular a build plane (17) in which the build material (3) is applied to be irradiated, wherein the irradiation device (4) is adapted to generate at least one irradiation region (8), in particular a melt pool, in the determination plane (6), characterized by a determination device (10) that is adapted to determine a focal position of the energy beam (5) and/or a difference between a reference focal position and an actual focal position of the energy beam (5) based on radiation (9) that is emitted from at least one irradiation region (8).
