Advances in printed electronics are predicated on the integration of sophisticated printing technologies with functional materials. Although scalable manufacturing methods, such as letterpress and flexographic printing, have significant history in graphic arts printing, functional applications require sophisticated control and understanding of nanoscale transfer of fluid inks. Herein, a versatile platform is introduced to study and engineer printing forms, exploiting a microscale additive manufacturing process to design micro‐architected materials with controllable porosity and deformation. Building on this technology, controlled ink transfer for submicron functional films is demonstrated. The design freedom and high‐resolution 3D control afforded by this method provide a rich framework for studying mechanics of fluid transfer for advanced manufacturing processes.

研究使用微结构材料进行浮雕打印的多孔介质

印刷电子技术的进步取决于将先进的印刷技术与功能材料相结合。尽管可缩放的制造方法（例如凸版印刷和柔性版印刷）在图形艺术印刷中具有重要的历史，但是功能应用程序需要复杂的控制和对流体墨水纳米级转移的理解。在这里，引入了一个多功能的平台来研究和设计打印表单，利用微尺度的增材制造工艺来设计具有可控制的孔隙率和变形的微结构材料。在此技术的基础上，展示了用于亚微米功能膜的受控油墨转移。
