    摘要: A continuous inkjet printer in which a continuous ink stream is deflected at the printhead nozzle bore without the need for charged deflection plates or tunnels. The printhead includes a primary ink delivery channel which delivers a primary flow of pressurized ink through an ink staging chamber to the nozzle bore to create an undeflected ink stream from the printhead. A secondary ink delivery channel adjacent to the primary channel is controlled by a thermally actuated valve to selectively create a lateral flow of pressurized ink into the primary flow thereby causing the emitted ink stream to deflect in a direction opposite to the direction from which the secondary ink stream impinges the primary ink stream in the ink staging chamber. A method of fabricating the printhead includes layering of the thermally actuated valve over the secondary ink delivery channel formed in a silicon substrate and creating the ink staging chamber over the delivery channels with sacrificial material which is later removed through the nozzle bore etched into the chamber wall formed over the sacrificial material.

    摘要: A method of forming a fluid chamber and a source of fluid impedance includes providing a substrate having a surface; depositing a first material layer on the surface of the substrate, the first material layer being differentially etchable with respect to the substrate; removing a portion of the first material layer thereby forming a patterned first material layer and defining the fluid chamber boundary location; depositing a sacrificial material layer over the patterned first layer; removing a portion of the sacrificial material layer thereby forming a patterned sacrificial material layer and further defining the fluid chamber boundary location; depositing at least one additional material layer over the patterned sacrificial material layer; forming a hole extending from the at least one additional material layer to the sacrificial material layer, the hole being positioned within the fluid chamber boundary location; removing the sacrificial material layer in the fluid chamber boundary location by introducing an etchant through the hole; forming the fluid chamber by introducing an etchant through the hole; and forming a source of fluid impedance.
