Abstract (en)
[origin: WO2019141410A1] By means of a device for producing articles by the method of selective laser melting, at least one article (21, 23, 25, 26, 27) that has at least one specific geometrical feature is built up by applying certain irradiation parameters, wherein the radiation emanating from locations (33) that are currently being irradiated, in particular the local heating of the material, is contactlessly detected by means of at least one sensor (31) in association with localisation data of the irradiated location (33) concerned and wherein optimised irradiation parameters are determined on the basis of the data recorded - and locations to be irradiated are archived in association with relevant localisation data for use in the production of articles that have the specific geometrical feature by the method of selective laser melting.
