Triply periodic minimal surface (TPMS) has been widely used in biology due to its excellent biological, controllable mechanical, and material transport properties. In this study, four types of TPMS structures with silicon nitride (SiN) ceramic were successfully prepared using digital light processing (DLP) with different minimal surface equations. The influence of different TPMS structures on the mechanical and biological properties of SiN ceramic was systematically investigated. Results indicated a better cell proliferation ability in the D structure compared with three other structures, with favorable compressive strength and Young's modulus of 51.84 ± 8.85 MPa and 3.33 ± 0.08 GPa, respectively.
三重周期极小曲面（TPMS）因其优异的生物学、可控的力学和物质传输特性而在生物学中得到广泛应用。在本研究中，使用数字光处理（DLP）结合不同的极小曲面方程，成功制备了四种含有氮化硅（SiN）陶瓷的TPMS结构。系统研究了不同TPMS结构对SiN陶瓷力学和生物学性能的影响。结果表明，与其他三种结构相比，D结构具有更好的细胞增殖能力，其抗压强度和杨氏模量分别为51.84±8.85 MPa和3.33±0.08 GPa。
