1 Introduction The use of Direct Laser Writing (DLW) for manufacturing and laser-based processing is increasing due to the availability of low-cost lasers. One distinguishes between additive, subtractive, and transformative DLW. The latter is a special case where a precursor material is chemically or structurally changed by the laser irradiation as in the case of laser-induced pyrolysis.[1] The discovery of laser-induced pyrolysis of polymers, which enables the maskless patterning of conductive ...
