Method of manufacturing a sidewall actuator array for an ink jet printhead in which a series of longitudinally extending, generally parallel grooves are formed in a body portion of the ink jet printhead. In various embodiments thereof, the body portion may be comprised of a lower body portion formed of an inactive material and an intermediate body portion formed of an active material, a lower body portion formed of active material poled in a first direction and an intermediate body portion formed of active material poled in a second, opposite direction, a lower body portion formed of active material poled in a first direction, a insulative spacing portion and an intermediate body portion formed of active material poled in a second, opposite direction, or a single body portion formed of an active material. After forming grooves therein, a layer of conductive material is deposited on inner side surfaces exposed during the grooving step. If the ink jet printhead is comprised of a single active body portion, the grooves formed in the lower body portion are then deepened to expose second interior side surfaces of the lower body portion. A bottom side surface of an inactive upper body portion is then mounted to the top side surface of the active intermediate body portion to form the sidewall actuator array.
