Quality management

Quality monitoring and assurance in additive manufacturing

Stable processes and optimized quality management are prerequisites for the integration and use of additive technologies in industrial production. Reliable statements about the mechanical properties of the manufactured components are just as much a part of this as intelligent monitoring and documentation strategies for processes and machines in powder bed and deposition welding processes.

In practice, quality control of manufactured components often takes place after the build-up process. This is complex and expensive. We develop solutions to monitor relevant influencing factors already during the additive process and use state-of-the-art testing methods and sensor technology for this purpose. All in all, we work with you to establish a comprehensive quality management strategy along the entire process chain, thus enabling you to achieve robust additive series production.

Quality management for reliable and robust additive manufacturing

Together with partners from industry and science we develop quality routines along the additive process chain.

Sensor technology in additive components

We develop solutions for embedding sensor technology in safety-critical aerospace structural components and highly stressed functional elements in power engineering.


Certify as you build

With the aid of artificial neural networks, we detect important process parameters during additive manufacturing and can make predictions about component quality on this basis.
