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%。

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
