摘要： A printer includes a printhead configured to eject high viscosity material and refill a reservoir in the printhead with high viscosity material. The printhead includes a transducer having an electroactive element and a member to which the electroactive element is mounted. An electrical signal activates the electroactive element to move the electroactive element and the member in the reservoir of high viscosity material. This movement thins the high viscosity material and enables the printhead to eject the thinned material while refilling the reservoir. The apertures through which the thinned material is ejected share a common manifold without separate chambers for each of the apertures.

摘要： A printer includes a printhead configured to eject high viscosity material and refill a manifold in the printhead with high viscosity material. The printhead includes a layer having an opening to form a reservoir to hold a volume of a high viscosity material and at least one member positioned within the receptacle formed by the opening in the layer. The at least one member has an electroactive element mounted to the member, and an electrical signal generator is electrically connected to the electroactive element. A controller operates the electrical signal generator to activate selectively the electroactive element with a first electrical signal to move the at least one member and thin the high viscosity material adjacent the at least one member to enable the thinned material to move away from the at least one member.

摘要： An ink jet printhead including a thermo-pneumatic actuator array for ejecting ink from an array of nozzles. The actuator array may include the use of a silicon-on-insulator (SOI) semiconductor wafer including a device layer, a handle layer, and a dielectric layer that physically separates the device layer from the handle layer to simplify printhead formation. During an exemplary process, the SOI wafer is attached to a heater wafer and a nozzle plate is attached to the dielectric layer such that, during use of the printhead, the device layer functions as an actuator membrane. Deflection of the device layer during use of the printhead creates a pressure within an ink chamber which causes ejection of ink from one of the nozzles of the array of nozzles.

摘要： Systems and methods of ejecting ink drops from an inkjet printer are disclosed. The systems and methods can include a printhead with one or more actuators with associated nozzles and membranes. A voltage waveform can be applied to the actuators to fill the actuators with a volume of ink and eject the ink through the nozzles as ink drops. The voltage waveform can have associated pre-fill voltage to fill the actuator with ink and a firing voltage to eject the ink. The actuator membranes can have multi-height dimples to protect the membranes from contacting electrodes and reduce the electric field.

摘要： An additive manufacturing system opens the valves in an extruder needed to form a swath and operates an actuator to move the extruder through a transition region with those valves open to establish an amount of extrusion material between a faceplate of the extruder and a portion of an object being formed that is adequate for formation of a swath. The length of the transition region is determined with reference to a viscosity of the material being extruded and a speed at which the extruder is moved to form the swath. The transition region can be perpendicular to a path of the extruder to form the swath or aligned with the path of the extruder to form the swath.
