ABSTRACT:
An acoustic ink printing print head utilizing metal alloy42is disclosed. Additionally, a process for incorporating the metal alloy42(alloy with approximately 42% nickel and 58% iron) to build the liquid level control/aperture plate defining an AIP print head is disclosed. The process consists of fabricating a channel plate and an aperture plate from the metal alloy42and bonding the two structures together thereby defining the liquid level control/aperture plate.
