In a jetting device for ejecting droplets of a relatively hot fluid, a fluid chamber body is made of a heat resistant material and an inner surface of the fluid chamber body, the inner surface defining a fluid chamber of the jetting device, is wettable by the fluid. This configuration provides that no additional force needs to be applied for forcing the fluid into an orifice, i.e. a narrow tube leading towards a nozzle. |
