An apparatus for additively manufacturing three-dimensional objects formed of successive layerwise consolidation of layers of a build material which can be consolidated by an energy beam. The apparatus may include a determination device confirmed to determine at least one parameter of the energy beam for a specific build material, wherein the determination device comprises at least one determination base body arrangeable or arranged in a beam guiding plane, in particular a build plane; and a tempering unit confirmed to temper the determination base body. Determination devices, along with methods, are also provided for determining at least one parameter of an energy beam of an apparatus for additively manufacturing three-dimensional objects.

Apparatus for additively manufacturing three-dimensional objects

Apparatus () for additively manufacturing three-dimensional objects () by means of successive layerwise selective consolidation of layers of a build material () which can be consolidated by means of an energy source (), which apparatus () comprises an optical unit () with at least one optical surface () arranged in a process chamber () of the apparatus (), wherein the apparatus () comprises at least one determination device () with at least one light source () and at least one determination unit () adapted to determine at least one radiation parameter of radiation () emitted from the light source () and reflected at the optical surface () of the optical unit (), wherein the determination device () is adapted to determine at least one condition information of the optical unit () based on the determined radiation parameter.

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.
