Abstract

A method and an arrangement for producing a workpiece using additive manufacturing techniques involve in-process measurement in order to determine individual characteristics of one or more workpiece layers. In particular, dimensional and/or geometrical characteristics of a workpiece layer are measured before the next workpiece layer is produced. Advantageously, the measurement results are fed back into the production process in order to increase accuracy and precision of the production process.
