A method for forming a print head having a plurality of reentrant structures to reduce wetting of the print head surface by the ink during use, and a resulting structure. The method can include the use of a single photosensitive layer to form plurality of reentrant structures, each having a pillar and a cap which overhangs the pillar. A plurality of print head nozzles can also be formed during the formation of the reentrant structures. Embodiments can include the formation of pillars, caps, and nozzles using three different masks, two different masks, or a single mask.
