Method of manufacture of a PTFE surface shooting shuttered oscillating pressure ink jet printer

摘要

A method of manufacturing an ink jet printhead includes providing a substrate. A doped layer is deposited on the substrate and is etched to create an array of nozzles on the substrate with a nozzle chamber in communication with each nozzle. Planar monolithic deposition, lithographic and etching processes are used to form a shutter for openably closing each nozzle chamber and a coiled, thermally responsive actuator to which the shutter is connected for displacing the shutter to open and close the nozzle on demand for controlling ejection of ink from the nozzle.
