Abstract
An inkjet print head comprises a fluid channel, the fluid channel including a pressure chamber; a piezo actuator including an active piezo stack and a membrane, the active piezo stack being provided at a surface of the membrane and the membrane forming a flexible wall of the pressure chamber, and a cavity having a cavity dimension determining a wall dimension of the membrane. The method of manufacturing such a print head includes selecting a desired actuator compliance; manufacturing a first print head layer including the piezo actuator; determining at least one actual actuator property of the piezo-actuator; determining a desired wall dimension based on the actual actuator property such that the combination of the piezo actuator and the membrane having the desired wall dimension provides for the desired actuator compliance; and manufacturing a second print head layer including the cavity.
