In this work, the possibility of shaping a glass-filled photosensitive polymer resin with Digital Light Processing (DLP) into a complex 3D structure and transforming it subsequently into a bioactive glass-ceramic scaffold was investigated. The influence of the printing conditions and the heat-treatment was studied using a 41 vol% glass-filled acrylated polymer resin. Scaffolds with designed architecture were turned into a wollastonite-diopside glass-ceramic at 1100 °C. They completely maintained their shape, exhibited no viscous flow and showed a homogenous linear shrinkage of around 25%. At 83 vol% porosity structures with Kelvin cell design exhibited a compressive strength exceeding 3 MPa, demonstrating that the material is suitable for the fabrication of bioceramic scaffolds for bone tissue engineering applications.

在这项工作中，研究了使用数字光处理（DLP）将玻璃填充的光敏聚合物树脂成型为复杂的3D结构，然后将其转换为生物活性玻璃陶瓷支架的可能性。使用41％（体积）玻璃填充的丙烯酸酯化聚合物树脂研究了印刷条件和热处理的影响。在1100°C下，将具有设计架构的支架转变为硅灰石-透辉石玻璃陶瓷。它们完全保持其形状，没有粘性流动，并显示出约25％的均匀线性收缩率。开尔文细胞设计的孔隙率为83％（体积），结构的抗压强度超过3 MPa，表明该材料适用于制造用于骨组织工程应用的生物陶瓷支架。
