Abstract
Today’s manufacturing processes, especially 3D printing with powder or wire, presuppose Industry 4.0 solutions, which require supervision of every single production step. Transforming machine elements into intelligent cyber-physical systems involves the integration of smart sensors for condition and process monitoring. As photonic solutions are by nature contact-free processes it would be advantageous if the sensor is based on light as well, if the light could be coupled into the beam path of the processing laser and if the sensor can measure surface topography in micrometer resolution. In this case, the production process can be directly connected to the CAD data set, the process could be controlled to eliminate geometrical deviations to the desired geometry and first-time-right is not a pious hope anymore. We talk about controlled individualized lot size 1 production based on OCT sensor technology.

Dr. Markus Kogel-Hollacher started his work in the laser industry in 1994 at the Fraunhofer Institute for Laser Technology (Aachen).
After graduating from RWTH Aachen University in 1996, he continued his work at Precitec in Germany. This work has been extensively discussed in several journals and presented at various conferences. In 2008 he obtained his Ph.D. at the Technical University of Berlin, Germany.
Dr. Markus Kogel-Hollacher is an innovator in photonic sensor technology for various applications. Working together with RTD performers and end users one of his guiding principles is to continuously increase the reliability and the use of process monitoring and process control devices in laser materials processing.
Dr. Kogel-Hollacher has received the prestigious PRISM Award in 2023 for his innovation bringing OCT sensor technology into semiconductor industry. In 2012 and 2014 he was finalist of the European Innovation Award Laser Technology.
