Abstract

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, which apparatus comprises an irradiation device adapted to guide an energy beam across a build plane, wherein a calibration device is provided comprising a positioning unit, a determination unit and a calibration unit, preferably arranged in a process chamber of the apparatus, that is adapted to at least partially reflect the energy beam, wherein the irradiation device is adapted to guide the energy beam to the calibration unit for generating a reflected part of the energy beam, wherein the positioning unit is adapted to position the irradiation device dependent on at least one parameter of the reflected part of the energy beam determined via the determination unit.
