A method for operating a powder bed-based manufacturing device for additive manufacturing of a component from a powder material includes taking at least one optical recording of a working powder layer of the powder material on a construction location of the manufacturing device, locally evaluating the at least one optical recording, and examining the working powder layer for local coating errors using the evaluation of the at least one optical recording.

The present disclosure relates to a method for determining a beam profile of a laser beam, which is positioned by a scanner device in a processing field. The method includes: arranging at least one retroreflector in the processing field for irradiating powder layers of the scanner device; detecting laser radiation reflected back into the scanner device while the laser beam is scanned over the retroreflector; and determining the beam profile of the laser beam by using the laser radiation detected during the scanning travel over the retroreflector.
