以数字光处理（DLP）为代表的增材制造技术的崛起，对陶瓷微通道的推广应用具有重要意义。但目前SiC陶瓷微通道的DLP成形技术仍然存在成形精度差的难题，需要在实验和理论分析方面进行更加广泛和深入的探索。本项目拟用化学沉淀和着色法构筑“双-多层”纳米结构的改性SiC陶瓷粉体，并以改性SiC为原料，采用DLP技术制备高精度复杂结构SiC微通道。研究“双-多层”纳米结构的SiC物理性能调控机理和其成形精度，并基于立体光刻化成形技术（SL）固化模型，揭示陶瓷DLP成形精度控制机制，完善DLP技术的固化模型，同时研究DLP工艺与SiC微通道组织性能的映射关系，为推动微通道技术的工程应用提供重要的理论基础和技术支撑。

Digital Light Processing（DLP）, emerging as a significant additive Manufacturing (AM) technology, opens new possibilities for fabricating SiC micro-channel with a higher accuracy and complex structure. However, there are still many challenges of dimension precision via DLP method of SiC, which still needs more extensive and in-depth exploration in the experimental research and theoretical analysis. In this project, the "double-multi layers" structured SiC is prepared using chemical precipitation method and the SiC micro-channel with a complex structure and high resolution is prepared by DLP method. The properties of modified SiC is studied and its form accuracy is discussed. The mechanism of dimension resolution and DLP cure model will be then analyzed based on SL model theory. In addition, the effects of DLP processing on SiC microstructure and properties are studied. Based on this project, it will provide basic data and technical support for promoting application of micro-channel technology in industry field.
