先进陶瓷材料的脆性和复杂的制造方法限制了其应用。三维打印是制备复杂形状陶瓷的一种新方法。为此，制备了一种由SiBCN陶瓷前驱体聚合物和大体积分数的Si3N4晶须(高达60wt%的聚合物)组成的可打印浆料，并随后通过数字光处理(DLP)技术进行了印刷。我们成功地制备了复杂结构的陶瓷复合材料，并获得了高的弯曲强度(∼180 Mpa)。晶须的引入显著降低了陶瓷材料的线收缩和质量损失。比较了在不同温度下热解的印刷件的性能和结构，并讨论了微观结构与力学性能的关系。采用DLP三维打印技术制备了具有高机械性能的SiBCN/Si3N4w构件。
The application of advanced ceramic materials is limited by their brittleness and complicated manufacturing methods. Three-dimensional (3D) printing has emerged as a new method for the fabrication of complex-shaped ceramics. Herein, a type of printable slurry composed of SiBCN preceramic polymers and high-volume fractions of Si3N4 whiskers (up to 60 wt% of polymer) was prepared, and subsequently printed via digital light processing (DLP) technology. We successfully manufactured complex-structured ceramic composites and achieved high bending strength (∼180 MPa). The linear shrinkage and mass loss of the ceramic material were both significantly reduced after the introduction of whiskers. The properties and structure of the printed parts pyrolyzed at different temperatures were compared, and the relationship between the microstructure and mechanical properties discussed. SiBCN/Si3N4w components with high mechanical properties were manufactured using DLP 3D-printing technology.
