Zusammenfassung:A computer-implemented method of correlating monitoring data and post-manufacturing inspection data in powder-bed-based additive manufacturing of workpieces includes (a) providing monitoring data including anomaly detection information of a workpiece's geometry in a layerwise domain, (b) providing inspection data including defect information of the workpiece's geometry in a volumetric domain, (c) extracting a region-of-interest information from the monitoring data, and, either, (d1) transforming the defect information of the inspection data from the volumetric domain into the layerwise domain, or, (d2) transforming the anomaly detection information of the monitoring data from the layerwise domain into the volumetric domain, as well as, (e) computing a spatial overlap of the monitoring data of interest and the transformed inspection data.
