摘　　要：针对双组分水凝胶梯度材料3D打印机的静态混合管进行了优化设计。通过建立模型,采用模块化的分析设计方法,对不同设计参数的分离混合型的静态混合管进行了定性与定量地仿真分析。最优的设计结合改装的Prusa i3结构的3D打印系统,打印不同比例的聚乙烯醇(PVA)/海藻酸钠(SA)双组份水凝胶结构。通过多个虚拟打印头,进行了PVA/SA的梯度打印,并通过阈值分割验证梯度效果。展示了双组分静态混合管的新设计以及其在生物兼容性梯度功能材料打印的应用。The static mixing tube for two-component hydrogel 3D printing are designed and optimized.The split-and-recombine(SAR)static mixing tubes simulated with different parameters are qualitatively and quantitatively evaluated.The optimal design is installed on a modified Prusa 3D printer to print poly vinyl alcohol(PVA)/Sodium alginate(SA)two-component hydrogel structures.The gradient PVA/SA sample is then printed by multiple virtual print heads.The gradient effect is verified by threshold segmentation.This demonstrates the new design of static mixing tube and its potential application in biocompatible gradient functional material printing.
