AbstractIn one of the preferred embodiments, an inkjet printhead includes a nozzle member formed of a polymer material that has been laser-ablated to form tapered inkjet orifices. The nozzle member is then mounted to a substrate containing heating elements, each heating element being associated with a single orifice. In a preferred method, the orifices are formed by Excimer laser ablation.In other aspects of the invention, vaporization chambers as well as ink channels, providing fluid communication between an ink reservoir and the orifices, are also formed by Excimer laser ablation.
