Abstract
A method of producing a workpiece by using additive manufacturing techniques includes obtaining CAD data representing the workpiece with workpiece layer definitions defining workpiece layers. The method includes selecting a first workpiece layer definition. The method includes preparing a powder bed of powder material on a build platform. The method includes measuring individual characteristics of the powder material on the build platform using a measuring head. The method includes producing, based on the selected workpiece layer definition, a workpiece layer on the build platform. The producing includes controlling a layer tool to selectively melt or sinter the powder material on the build platform. The producing is further based on the measured individual characteristics of the powder material to correct for detected flaws in the powder bed. The method includes selecting each one of the workpiece layer definitions and repeating the preparing, the measuring, and the producing for the selected definition.
