A printhead assembly for an inkjet printer is provided. The assembly includes an outer shell of a hot rolled tri-layer laminate of two different metals, and a core element within the shell, the core element defining four separate ink reservoirs. Also included are a printhead constructed using MEMS techniques to provide the ink nozzles, chambers and actuators, and a micro molding for distributing ink from the ink reservoirs to the printhead. The tri-layer shell is configured such that the effective coefficient of thermal expansion of the shell as a whole is substantially equal to that of silicon. |
