Abstract

The mechanical properties of samples made by 3D printing from poly(lactic acid) (PLA) and PLA filled with 20, 40, 60 and 80 wt% PLA/Al2O3 (85/15) was evaluated. Addition of PLA/Al2O3 improved mechanical properties of PLA. Tensile strength increased by approx. 19%, tensile modulus by 27%, compression modulus by approx. 42%, flexural modulus by 70%, impact strength by 20% and hardness by approx. 14% compared with pure PLA.

通过聚乳酸-聚乳酸/Al2O3 三维打印技术获得的夹层产品的机械性能

对用聚乳酸（PLA）和填充 20、40、60 和 80 wt% 聚乳酸/Al2O3（85/15）的聚乳酸进行三维打印制成的样品的机械性能进行了评估。聚乳酸/Al2O3 的添加改善了聚乳酸的机械性能。与纯聚乳酸相比，拉伸强度提高了约 19%，拉伸模量提高了 27%，压缩模量提高了约 42%，弯曲模量提高了 70%，冲击强度提高了 20%，硬度提高了约 14%。
