Method and device for calibrating a manufacturing apparatus, and system

Abstract

The invention relates to a method for calibrating a manufacturing apparatus. The manufacturing apparatus is configured for the additive manufacture of three-dimensional workpieces by layer-by-layer solidification of raw material by means of location-selective irradiation. The method comprises using a multiplicity of measurement results of optical measurements carried out with a time offset to estimate at least one property of an irradiation point or / and irradiation pattern to be provided, with each measurement result specifying at least one property of an irradiation point or / and irradiation pattern at the respective measurement time. The method also comprises a calibration of the manufacturing apparatus on the basis of the estimated at least one property. The invention also relates to a device and a system.
