Method for creating surface microstructures

A method for creation of a desired surface microstructure, the method comprising the steps of:

• providing a material with a surface microstructure which has a topography, the surface microstructure being considered as the original surface microstructure, wherein the structure depth of the original surface microstructure is in the range from 10 nm to 100 μm;
• providing a 3D surface profilometer;
• acquiring digital data of the original surface microstructure topography with the 3D surface profilometer;
• providing a writing tool;
• processing the digital data of the original surface microstructure topography to obtain structure describing data to be written by the writing tool;
• providing the structure describing data for the desired surface microstructure to the writing tool;
• providing a target material;
• optionally providing a resin;
• creating the desired surface microstructure in or on the target material comprising writing with the writing tool a structure in or on the target material or in the resin using the structure describing data.
