Abstract
A fluid ejector includes a fluid ejection assembly, a housing, and an insert. The fluid ejection assembly includes one or more silicon bodies and a plurality of actuators. The one or more silicon bodies includes a silicon body having a plurality of fluid passages for fluid flow and a plurality of nozzles fluidically connected to the plurality of fluid passages. The plurality of actuators cause fluid in the plurality of fluid passages to be ejected from the plurality of nozzles. The housing assembly includes one or more plastic bodies, at least one plastic body attached to at least one silicon body to form a sealed volume on a side of the fluid ejection assembly opposite the nozzles. The insert is embedded in the at least one plastic body in proximity to the at least one silicon body, the insert having a coefficient of thermal expansion of less than 9 ppm/° C.
