Abstract
The disclosure provides methods for calibrating processing machines for the production of 3D components by irradiation of powder layers, wherein the processing machine includes a scanner device for positioning a laser beam in a processing field in which a height-adjustable construction platform for the application of the powder layers by sweeping at least two, e.g., three markings, e.g., in the form of spherical retroreflectors, which are applied on the construction platform and/or on a preform, by the laser beam, detecting laser radiation reflected back from the markings into the scanner device, determining actual positions of the markings, determining deviations of the actual positions of the markings from setpoint positions of the markings, and calibrating the processing machine by correcting the positioning of the laser beam and/or the position of the construction platform using the determined deviations. The disclosure also relates to associated processing machines.
