Abstract

This research examines the mechanical properties and water absorption of polycaprolactone (PCL) scaffolds reinforced with nano-hydroxyapatite (N-HA) particles, printed using a 3D printer based on fused deposition modeling (FDM) technology. Fabricating this composite material aims to replicate a tissue similar to bone tissue. Biocompatible N-HA (50% by weight) was utilized to fortify the matrix phase and enhance the mechanical properties. The compression test results showed that the addition of N-HA augmented the compressive strength and modulus of the scaffolds (with a nominal porosity of 60% and a filling pattern of 0/60/120) by 240% and 150%, respectively. Moreover, the water absorption increased by 600%.

基于熔融沉积建模的3D打印聚己内酯/纳米羟基磷灰石复合支架压缩力学性能和吸水性能优化

本研究利用基于熔融沉积建模(FDM)技术的3D打印机，研究了纳米羟基磷灰石(N-HA)颗粒增强聚己内酯(PCL)支架的力学性能和吸水性。制造这种复合材料的目的是复制类似骨组织的组织。生物相容性N-HA(重量比50%)用于强化基质相和提高力学性能。压缩试验结果表明，N-HA的加入使支架(名义孔隙率为60%，填充模式为0/60/120)的抗压强度和模量分别提高了240%和150%。吸水率提高了600%。
