Zusammenfassung:A method of producing a workpiece includes obtaining CAD data representing the workpiece in multiple workpiece layers. The CAD data includes multiple workpiece layer definitions corresponding respectively to the workpiece layers. The method includes selecting a first workpiece layer definition, preparing a powder bed of powder material on a build platform, and producing, based on the selected workpiece layer definition, a workpiece layer on the build platform by controlling a layer tool to selectively melt or sinter the powder material on the build platform. The method includes assessing the produced workpiece layer, including measuring the produced workpiece layer using a measuring head, analyzing the measurements of the produced workpiece layer, and, in response to the analysis indicating that the produced workpiece layer is defective, reprocessing the produced workpiece layer by controlling the layer tool to selectively melt or sinter the powder material on the build platform.
