Zusammenfassung:	A printhead and a method of manufacturing a printhead are provided. The printhead includes a polymeric substrate including a surface. Portions of the polymeric substrate define a liquid chamber. A material layer is disposed on the surface of the polymeric substrate. Portions of the material layer define a nozzle bore. The nozzle bore is in fluid communication with the liquid chamber.
