Laser-microtextured surfaces have gained an increasing interest due to their enormous spectrum of applications and industrial scalability. In this frame, several research studies have demonstrated how laser-based fabrication methods can be used to produce functional surfaces. Furthermore, it has been demonstrated is many cases, that the combination of structures with feature sizes in different ranges (e.g., microelements decorated with nanostructures) can not only further enhanced specific functions but also to provide surfaces with several functionalities. In this context, this talk shows how Direct Laser Interference Patterning (DLIP), Direct Laser Writing (DLW) and Laser Induced Periodic Surface Structures (LIPSS) can be combined, reaching advanced functionalities on technological relevant materials.
