Bringing the Direct Laser Interference Patterning Method to Industry: a One Tool-Complete Solution for Surface Functionalization

Direct Laser Interference Patterning is an emerging technology capable to produce micro- and nanostructured surfaces on a wide variety of materials. Although, this method has shown to be ca-pable to produce functionalized surfaces in a one-step process, it will have impact on real applica-tions only if compact systems and solutions are developed. This study shows recent developments of interference patterning optical heads capable to produce periodic patterns at high fabrication speeds (0.1 - 5 m2/min) as well as to solutions to be integrated in roll-to-roll processes. A concept of an interference patterning system (DLIP-µFab) is also described. Application examples showing control of tribological properties of 100Cr6 steel, cell orientation on patterned polyimide surface as well as the fabrication of high resolution decorative elements are discussed.
