AUTOMATED CALIBRATION OF AN APPARATUS FOR THE FULLY PARALLELIZED ADDITIVE MANUFACTURING OF A COMPONENT WITH COMBINED WORKING AREAS

摘要

Arrangement (10) for the powder-bed-based additive manufacturing of a component (100), wherein the arrangement (10) comprises the following: a housing (12), which comprises a building volume (14), wherein the building volume (14) comprises a building area (16); at least three marker devices (20), which are fastened in or on the housing (12), wherein each marker device (20) is suitable for projecting a light reference marking (22) onto a component (100) lying on the building area (16) and/or onto the building area (16); a laser device (30) for the laser processing of a powder bed for generating a component (100) on the building area (16) by to means of additive manufacturing, wherein the laser device (30) is set up for the laser processing of an associated working area (32a-32d), wherein the laser device (30) comprises a detection device (34), which is set up to sense the light reference markings (22); and a control unit (40), which is set up to calibrate the laser device (30) on the basis of the light reference markings (22) sensed by the detection device (34).
