FUJIFILM Dimatix Uses MEMS Simulation for Inkjet Printhead Design
Chris Menzel, FUJIFILM Dimatix, USA
FUJIFILM Dimatix, a top producer of commercial inkjet printheads, uses multiphysics simulation to develop MEMS actuators, which their newest ink deposition projects are based on. Chris Menzel, a principal scientist on the research team at FUJIFILM Dimatix, studies printhead actuation to further the design of FUJIFILM's newest unimorph diaphragm actuators.
The team used COMSOL Multiphysics® to create a model that includes the high-performance thin-film piezoelectric layer (PZT), silicon membrane, electrodes, and the pressurized ink chamber. This model enabled them to determine the deflection of the actuator in response to electrical stimulation of the PZT, gaining a better understanding of the ins and outs of their actuator and jet.
