A method and an arrangement for producing a workpiece using additive manufacturing techniques involve pre-process, in-process and post-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, production parameters are controlled in response to individual material characteristics determined prior to the production process. Also advantageously, measurement results are fed back into a production process in order to increase accuracy, reliability, repeatability and precision of the production process.

Adaptive closed-loop control of additive manufacturing for producing a workpiece

Methods and devices for additive manufacturing of workpieces are provided. For analysis during production, a test is carried out using a selected test method. The test results are compared with simulated test results derived during a simulation of the manufacturing and testing. The test may use one or more of a laser ultrasound test unit, an electronic laser speckle interferometry test unit, an infrared thermography test unit, or an x-ray test unit.
