Abstract

A method of producing a workpiece by using additive manufacturing techniques includes obtaining computer-aided design data representing the workpiece in multiple layers. The method includes providing build platforms and layer tools. Each layer tool is moveable relative to a respective build platform and configured to generate or solidify a material layer on the respective build platform. The method includes producing a first defined material layer of the workpiece on a first build platform by controlling a first layer tool according to a first layer definition. The method includes transferring the first defined material layer from the first build platform to a second build platform and measuring the first defined material layer using a first measuring head to measure individual characteristics. The method includes producing further material layers of the workpiece by controlling a second layer tool in accordance with further layer definitions as a function of the measured individual characteristics.
