Acoustic emissions expose whether a laser process runs steadily or drifts off course. Fraunhofer IWS develops acoustic monitoring systems that evaluate laser machining directly and instantly. The goal: robust, economical process control to interpret sound emissions in real time and detect deviations immediately. The Dresden Institute showcases a market-ready module at Laser World of Photonics 2025 (June 24–27, Munich) while expanding the approach to laser welding and cutting applications.

A new testing system shall detect leaks in filter modules automatically, non-destructively, and in real time. DBI Gas- und Umwelttechnik spearheads the CLeo project, where the system is currently under development. The Fraunhofer Application Center for Optical Metrology and Surface Technologies AZOM contributes a laser-based leak detection method and an AI-driven analysis process. The system aims to fundamentally improve the currently manual quality control in membrane production. It will help reduce production costs, meet environmental standards, and ensure the long-term quality of industrial filtration systems – efficiently, precisely, and sustainably.

Dr. Filofteia-Laura Toma, Senior Research Scientist at the Fraunhofer Institute for Material and Beam Technology IWS in Dresden, has been named the recipient of the 2025 “TSS President’s Award for Meritorious Service”. Presented on May 7 by the U.S.-based Thermal Spray Society (TSS), the award honors her scientific excellence and her long-standing leadership within the international materials engineering community.

In an effort to improve both the cost efficiency and quality of hydrogen-powered vehicle production, a consortium of Fraunhofer Institutes is developing innovative manufacturing techniques for fuel cells as part of the “H2GO” project. Key innovations originate from the Fraunhofer Institute for Material and Beam Technology IWS and the Fraunhofer Institute for Machine Tools and Forming Technology IWU. Engineers from Dortmund, Dresden, and Chemnitz are creating modular components for bipolar plate (BPP) production lines, which are crucial elements of fuel cell stacks.
