直接激光写入（DLW）是一种三维（3D）制造技术，其在亚微米尺度上提供巨大的结构控制，但在需要包括多于一种材料的微结构的情况下仍然受到限制。在这里，我们提出了一种可访问的微流体多材料DLW（mu FMM-DLW）策略，该策略使3D纳米结构组件能够以100 +/- 70 nm（.X）和190 +/- 170 nm（.Y）的平均材料配准精度进行打印-与传统的多材料DLW方法相比，这是一个显着的改进。用多达五种材料打印3D微结构的结果表明，mu FMM-DLW可用于需要几何复杂的多材料微系统的应用，例如光子学，超材料和3D细胞生物学。
Direct laser writing (DLW) is a three-dimensional (3D) manufacturing technology that offers vast architectural control at submicron scales, yet remains limited in cases that demand microstructures comprising more than one material. Here we present an accessible microfluidic multi-material DLW (mu FMM-DLW) strategy that enables 3D nanostructured components to be printed with average material registration accuracies of 100 +/- 70 nm (.X) and 190 +/- 170 nm (.Y) -a significant improvement versus conventional multimaterial DLW methods. Results for printing 3D microstructures with up to five materials suggest that mu FMM-DLW can be utilized in applications that demand geometrically complex, multi-material microsystems, such as for photonics, meta-materials, and 3D cell biology.
