Video Demonstration of the Combination of Additive and Subtractive Laser Processing for Manufacturing of Small Holes and Narrow Grooves

This video illustrates a novel approach combining additive and subtractive laser processes at the layer level (AddSub). This quasi-simultaneous manufacturing process enables the fabrication of small structures with high aspect ratios, including narrow grooves below 50 µm in width. The technique demonstrates significant potential for applications in fields such as electric drives and fuel cells, where precision and design freedom are critical.
