EP3610970A1
METHOD FOR CALIBRATING AN APPARATUS FOR ADDITIVELY MANUFACTURING THREE-DIMENSIONAL OBJECTS
Publication/Patent Number: EP3610970A1 Publication Date: 2020-02-19 Application Number: 18188779.5 Filing Date: 2018-08-13 Inventor: Petratschek, André   Hiemann, Denise   Assignee: Concept Laser GmbH   IPC: B22F3/105 Abstract: Method for calibrating an apparatus (1) 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 (2 - 5), which apparatus (1) comprises at least two irradiation units (7 - 10), each adapted to generate an energy beam (2 - 5), wherein each irradiation unit (7 - 10) is adapted to guide the corresponding energy beam (2 - 5) across an individual guiding region (21, 23, 25, 27) in a build plane (11), wherein at least two guiding regions (21, 23, 25, 27) overlap in at least one overlap region (29 - 33), comprising the steps: - generating at least one calibration pattern (14 - 17) in the at least one overlap region (29 - 33) via each of the at least two energy beams (2 - 5), wherein the at least two calibration patterns (14 - 17) are generated in defined relative positions forming a superordinate pattern (18) in the at least one overlap region (29 - 33) - determining a calibration status of the at least two irradiation units (7 - 10) based on a calibration information relating to the spatial arrangement of the at least two calibration patterns (14 - 17) in the superordinate pattern (18), in particular the relative position - adjusting the at least one irradiation unit (7 - 10) dependent on the calibration status.
