Abstract
Method for calibrating an irradiation device for additively manufacturing three-dimensional objects by successive layerwise selective irradiation and consolidation of layers of a build material which can be consolidated by means of an energy beam, which irradiation device comprises a first and a second irradiation unit adapted to guide a first and a second energy beam, wherein at least two first and two second calibration patterns are generated, wherein the at least two first calibration patterns are generated in at least two different first positions via the first energy beam and the at least two second calibration patterns are generated in at least two different second positions via the second energy beam and position information are determined relating to the positions of the at least two first and second calibration patterns and calibration information are generated relating to a calibration status of the irradiation device based on the determined position information.
