    • A co-extrusion device has at least one first inlet port to receive a first material, at least one second inlet port to receive a second material, a first combining channel arranged to receive the first material and the second material and combine the first and second materials into a first combined flow flowing in a first direction. a splitter channel arranged to receive the first combined flow and to split the first combined flow into at least two split flows in a second direction at least partially orthogonal to the first direction, wherein each split flow consists of the first and second materials, and a second combining channel arranged to receive the split flows and combine the split flows into a second combined flow in the first direction, and at least one exit orifice arranged to allow the materials to exit the device as a single flow. A method for depositing a structure comprising interdigitated materials includes merging flows of at least two materials in a first direction into a first combined flow, dividing the first combined flow in a second direction to produce at least two separate flows, wherein the second direction is perpendicular to the first direction, and merging the two separate flows into a second combined flow.
    • 共挤出装置具有至少一个用于接收第一材料的第一入口端口,用于接纳第二材料的至少一个第二入口端口,布置成接收第一材料和第二材料的第一组合通道,并将第一和第二 材料进入沿第一方向流动的第一组合流。 分配器通道,其被布置成接收第一组合流并且将第一组合流在至少部分地与第一方向正交的第二方向上分裂为至少两个分流,其中每个分流由第一和第二材料组成, 第二组合通道,其布置成接收分流,并将分流流合并成沿第一方向的第二组合流,以及布置成允许材料以单一流动方式离开设备的至少一个出口孔。 一种用于沉积包括交错材料的结构的方法包括将第一方向上的至少两种材料的流合并成第一组合流,在第二方向上分割第一组合流以产生至少两个单独的流,其中第二方向垂直 到第一方向,并将两个单独的流合并成第二组合流。
