摘要
3D打印制备陶瓷可以实现结构-材料设计一体化,为复杂形状陶瓷材料快速成型提供了新途径。但是传统的3D打印制备陶瓷是以陶瓷粉末或陶瓷颗粒为打印材料,存在陶瓷构件尺寸精度差、表面光洁度低和力学性能不佳等问题。近年来,以聚合物前驱体为打印材料,通过3D打印成型、高温裂解等工艺制备高性能陶瓷技术的出现为改善这些不足提供了新方法,成为3D打印陶瓷领域的研究热点。本文概述了聚合物前驱体3D打印制备高性能陶瓷的研究进展,重点阐述了本体聚合物前驱体、聚合物前驱体/光敏化合物、聚合物前驱体/巯基化合物、光敏基团改性聚合物前驱体、增强体/聚合物前驱体五种典型材料体系的研究现状,并对其今后的发展方向进行了展望。
3D printing to prepare ceramics can realize structure-material design integration,which provides new opportunities for rapid prototyping of ceramic materials with complex shapes.However,traditional 3D printing for preparing ceramics uses ceramic powder or ceramic particles as the printing material,which has problems such as poor dimensional accuracy of ceramic components,low surface finish,and poor mechanical properties.In recent years,the emergence of technology that uses polymer precursors to produce ceramic materials with complex shapes through processes of 3D printing molding and pyrolysis provides new methods to improve this situation.It has become one of the most popular research topics in the field of 3D printing to prepare ceramics.This article summarizes the research progress of 3D printing of polymer precursor derived high performance ceramics,focusing on research status of the five typical material systems:bulk polymer precursors,polymer precursors/photosensitive compounds blends,polymer precursors/thiol compounds blends,photosensitive groupmodified polymer precursors,and reinforcement/polymer precursors.Besides,an outlook for future development of 3D printing of polymer precursor derived advanced ceramics is given.
