摘要： A printhead includes a chamber layer and at least two orifice layers. A first orifice layer is disposed on the chamber layer, and a second orifice layer is disposed on the first orifice layer. The second orifice layer has at least one counterbore formed therein. A first nozzle is formed through both orifice layers and produces droplets of a first drop weight. A second nozzle is formed through the first orifice layer, coincident with the counterbore, and produces droplets of a second drop weight that is different than the first drop weight. In one embodiment, the printhead is used in a stand-alone fluid-dispensing device.

摘要： A fluid-ejection device includes a handheld and/or mountable enclosure, a removable tip having a fluid-ejection mechanism, a first fitting extending from the enclosure and receptive to placement of the removable tip thereon, and a controller situated within the enclosure to cause the removable tip to eject the fluid. The fluid-ejection device may also include tip-extension assembly having an electrical cable connecting to the controller and having a second fitting receptive to placement of the removable tip thereon. The electrical cable permits the removable tip to be located substantially independently of the enclosure. The fluid-ejection device may further include tubings fluidically couplable with the removable tip through at least one of the first and second fittings to provide fluid to the removable tip and to regulate backpressure of the fluid within the removable tip.

摘要： A solid freeform fabrication system includes a powdered build material deposited as a layer in a fabrication bin; a binding powder deposited as a layer over the layer of powdered build material; and an activating fluid that is selectively dispensed from an ejection head to activate the binding powder. The activated binding powder then selectively binds the build material into a cross-section of an object being fabricated.

摘要： A fluid-ejection printhead die includes a fluid-ejection firing element and an electrochemical cell. The fluid-ejection firing element is to cause droplets of fluid to be ejected from the fluid-ejection printhead die. The electrochemical cell is to measure an electrical property of the fluid. The fluid-ejection firing element and the electrochemical cell are both part of the fluid-ejection printhead die.
