An inkjet nozzle assembly includes: a nozzle chamber having a nozzle opening and an ink inlet; and a thermal bend actuator for ejecting ink through the nozzle opening. The actuator includes: an active beam for connection to drive circuitry; a first passive beam fused to the active beam; and a second passive beam fused to the second first passive beam. The first passive beam is sandwiched between the active beam and the second passive beam such that when a current is passed through the active beam, the active beam expands relative to the passive beams, resulting in bending of the actuator and ejection of ink through the nozzle opening.
