    Abstract: A nozzle plate defines at least one nozzle connected to the nozzle plate at a base, wherein the at least one nozzle has a height and a top having an inner width and an outer width, wherein a ratio of the height to the inner width is greater than 5, and wherein the nozzle plate comprises a borosilicate glass. The nozzle plate is formed via a method including providing a silicon wafer having a surface; providing a borosilicate glass wafer having a surface; etching the surface of the silicon wafer to form a plurality of trenches in the surface; anodically bonding the etched surface of the silicon wafer to the surface of the borosilicate glass wafer to form a two layer composite; heating the two layer composite at a temperature of at least about 750° C.; and releasing the silicon wafer from the borosilicate glass to form the nozzle plate.

    Abstract: Methods of coating a substrate are provided. In an exemplary embodiment, a coating composition is applied to the substrate with a high transfer efficiency applicator to produce a coating layer, where the high transfer efficiency applicator and the substrate remain spatially separate while the coating composition is applied. A droplet of the coating composition expelled from the high transfer efficiency applicator has a particle size of about 10 microns or greater. The coating composition has a viscosity of from about 1,000 to about 1,000,000 centipoise when the coating composition is subject to a shear rate of about 0.1 reciprocal seconds (s−1). However, the coating composition is non-Newtonian such that a coating composition viscosity decreases when the shear rate is increased to the coating composition. The coating layer is impinged with a gas such that a coating layer surface moves upon impingement with the gas.

    Abstract: Coating application systems and methods of using the same are provided. In an exemplary embodiment, a coating application system includes a support system defined in an XYZ coordinate system, where the XYZ coordinate system includes an X axis, a Y axis, and a Z axis that are all perpendicular to each other. The X and Y axes define an XY plane at a zero Z axis position. The support system includes a first and second bar both of which run in the X direction of the XY plane. A traveling rod is connected to the first and second bars and is configured to run in the X direction. A plurality of printheads are connected to the traveling rod, where the plurality of printheads include a first and second printhead that are configured to articulate independent of each other.
