Abstract

Validating additively manufactured components is carried out by transmitting to a distributed validation network printing specification data for a component that is to be additively manufactured, validating the printing specification data, and adding the printing specification data, together with a cryptographically encoded checksum, to a print history log, transmitting the printing specification to a 3D printing device, and implementing a generative manufacturing process for the component that is to be additively manufactured in accordance with the transmitted printing specification data. While the generative manufacturing process is being carried out, in each case following specified manufacturing stages, a plurality of manufacturing parameters prevailing in the preceding manufacturing stage are transmitted to the distributed validation network. Subsequent manufacturing stages are released in order to be implemented in the 3D printing device only if the transmitted manufacturing parameters have been successfully matched to the printing specification data stored in the print history log.
