中文摘要： 微型加工厂是制备微/中尺度3D结构的前沿制造学科，而在其中有效集成增量制造3D打印方式已经成为研究重点。然而,现有的3D打印技术分辨率无法满足微/中尺度制造的精度要求。本项目拟提出具有数字化制版功能和2400dpi高分辨率的液体3D沉积方法，用于制备微/中尺度3D结构。该方法首次采用静电成像和高分辨率曝光技术，在制版辊表面进行固体颗粒制版，而版图案能够在每次液体层沉积后进行更改。本项目将进一步基于该数字化固体版，通过开展对于光固液体成分、制版辊表面、固体颗粒表面的浸润性研究，以完成液体有效填充版中的无颗粒空穴，形成液体图案薄层，而其层厚可以控制在3 - 5μm。同样的浸润性分析可以完成光固液体在衬底表面的有效沉积，而最终完成液体固化。本项目将为研究高分辨率液体3D沉积方法提供新的理论基础，有效促进3D打印技术在微型加工厂中的实现，完成对于微/中尺度3D结构的制备。

英文摘要： Microfactory is a frontier manufacturing discipline for fabricating micro/meso-scale 3D structure, and in which the effective integration of the incremental manufacturing 3D printing method has become a research focus. However, the printing resolution of existing 3D printing technology cannot meet the precision requirement of micro / meso-scale manufacturing. This research project intends to raise a novel liquid 3D deposition method with digital platemaking capability and 2400dpi high resolution, for preparation of micro / meso-scale 3D structure. The proposed method, for the first time, uses electrophotographics and high-resolution exposure technique to make a solid-particle plate on a platemaking roller, while the version of the pattern can be immediately changed after each cycle of liquid layer deposition. Based on the digital plate, this project will carry out the wettability studies among the components of photocurable liquid, the surface of platemaking roller, the surface of the solid particle, for effectively filling the liquid into the particleless cavity on the plate to form a thin layer of liquid pattern. Its thickness can be controlled at 3 - 5μm. The same wettability analysis can be done for effective deposition of the photocurable liquid on the substrate and the final solidation of the liquid. The project will provide a new theoretical foundation for studying liquid 3D deposition method to effectively promote the application of 3D printing technology in microfactory for manufacturing micro / meso-scale 3D structure.
