Abstract
The invention concerns a method and a device for calibrating at least one scanning system (4, 5, 17) when producing an object (8) by additive manufacturing, wherein the coordinates of one or several reference positions are measured in the relative coordinate system of each scanning system (4, 5, 17), after which the calibration of each of the scanning systems is adapted starting from the measured coordinates of the reference positions.
