摘要:针对现有的熔融沉积成型(FDM)打印技术出丝不稳、打印速度较低以及打印材料受限等问题,通过不断优化打印参数(料筒温度、螺杆转速、挤出倍率以及打印速度),比较不同填充方式下打印件的力学性能,最终确定了针对聚乳酸(PLA)颗粒料的成型参数。基于这些成型...
The results showed that the PLA/n-HA composites proposed in this study were highly printable, and the printed scaffold showed tunable mechanical strength accompanied by the proportion of n-HA components. The biocompatibility and osteogenic induction properties were proved better than that of the pure...
