An inkjet nozzle assembly includes: a nozzle chamber having a floor and a roof spaced apart from the floor, the roof having a displaceable portion defining an ejection port; and an actuator for displacing the displaceable portion of the roof towards the floor. Displacement of the displaceable portion of the roof alters a volume of the nozzle chamber such that when the volume is altered, fluid is ejected from the ejection port.
