At the Simulation – Laser Processes and Components Workshop held on 12 – 13 March 2025 in Dresden, Prof. Andrés F. Lasagni from TU Dresden gave an invited talk on laser-based surface structuring. His presentation, titled “On the Simulation of Direct Laser Interference Patterning Surface Structuring Process in Metals: Temporal Evolution of Structure Formation and Marangoni Convection”, highlighted how simulation helps understand and improve the laser processing of metal surfaces.

The talk also introduced the CLASCO project, which is developing an innovative laser processing machine. CLASCO aims to enhance the post-processing of additively manufactured parts with complex geometries. In this context, laser interference patterning supported by simulation tools offers a promising method to tune surface functionalities in a controlled and efficient way.

With use cases from aerospace and biomedical applications, CLASCO addresses challenges related to the precision and performance of 3D-printed components. Accurate post-processing is essential to meet demanding technical requirements such as improved adhesion, wear resistance, and biological compatibility.

The workshop provided a valuable platform for discussing how simulation and laser technology can work together to support the next generation of high-performance parts.
