The optical stamping process makes it possible to generate microstructures precisely and reproducibly in a single laser pulse – without needing to scan the surface, a time-consuming process step. At the Fraunhofer Institute for Laser Technology ILT, researchers in collaboration with RWTH Aachen University.

For years, Design for Additive Manufacturing (DfAM) has been celebrated as a revolutionary discipline, one that empowers engineers to unlock geometric freedoms and create structures once deemed impossible. And indeed, today’s design and additive manufacturing ecosystem includes powerful tools that predict distortion, prevent build failures, and improve part quality through intelligent scanning and exposure strategies.

In today’s manufacturing landscape, the sensor is no longer just a passive data collector. As factories become increasingly digital and interconnected, smart sensors are emerging as foundational enablers of process optimization and seamless factory connectivity. They not only measure critical parameters but also analyze, communicate, and even trigger corrective actions in real time, moving quality management from reactive inspection to proactive control.

The measurement of roughness close to production is becoming increasingly important. In connection with the measurement of gears, roughness parameters are of great interest, for example, as they not only describe the surface topography in the micro- and nanometer range, but also characterize the running behavior of gearboxes. In addition to roughness, waviness also plays a role.
