    • Various fluidic techniques can employ ducting structures, such as microstructures, that extend between other components, such as plate-like structures. A ducting structure can, for example, include an inlet opening toward or near one plate-like structure, an outlet opening toward or near another plate-like structure, and a duct in which fluid flows after being received through the inlet opening and before being provided through the outlet opening. In some implementations, a ducting structure is photo-defined, such as by exposing a photoimageable structure and then removing either exposed or unexposed regions. In some implementations, a ducting structure is a freestanding polymer microstructure. In some implementations, ducting structures are microstructures that extend approximately the same length between first and second plate-like structures, and have a ratio of length to maximum cavity diameter of approximately two or more. A printhead implementation includes an array of such microstructures supported between drive side and drop side assemblies.
    • 各种流体技术可以采用在诸如板状结构的其他部件之间延伸的管道结构,例如微结构。 管道结构可以例如包括朝向或靠近一个板状结构的入口开口,朝向或接近另一个板状结构的出口,以及在通过入口开口之后流体流动的管道 通过出口开口提供。 在一些实施方案中,管道结构是光限定的,例如通过曝光可光成像的结构,然后去除暴露或未曝光的区域。 在一些实施方案中,管道结构是独立的聚合物微结构。 在一些实施方案中,管道结构是在第一和第二板状结构之间延伸大致相同长度的微结构,并且具有大约两个或更多个长度与最大腔直径的比率。 打印头实现包括支撑在驱动侧和液滴侧组件之间的这种微结构的阵列。
