Abstract

This review explores the impact of various additives on the mechanical properties of polylactic acid (PLA) filaments used in Fused Deposition Modeling (FDM) 3D printing. While PLA is favored for its biodegradability and ease of use, its inherent limitations in strength and heat resistance necessitate enhancements through additives. The impact of natural and synthetic fibers, inorganic particles, and nanomaterials on the mechanical properties, printability, and overall functionality of PLA composites was examined, indicating that fiber reinforcements, such as carbon and glass fibers, significantly enhance tensile strength and stiffness, while natural fibers contribute to sustainability but may compromise mechanical stability. Additionally, the inclusion of inorganic particulate fillers like calcium carbonate improves dimensional stability and printability, although larger particles can lead to agglomeration issues. The study highlights the potential for improved performance in specific applications while acknowledging the need for further investigation into optimal formulations and processing conditions.

提高聚乳酸（PLA）性能：熔融沉积模型（FDM）长丝添加剂的研究进展。

本文综述了各种添加剂对用于熔融沉积建模（FDM） 3D打印的聚乳酸（PLA）长丝力学性能的影响。虽然PLA因其可生物降解性和易用性而受到青睐，但其在强度和耐热性方面的固有局限性需要通过添加剂来增强。研究了天然纤维和合成纤维、无机颗粒和纳米材料对PLA复合材料的机械性能、可打印性和整体功能的影响，表明纤维增强剂，如碳纤维和玻璃纤维，可以显著提高拉伸强度和刚度，而天然纤维有助于可持续性，但可能会损害机械稳定性。此外，无机颗粒填料（如碳酸钙）的加入提高了尺寸稳定性和可印刷性，尽管较大的颗粒会导致结块问题。该研究强调了在特定应用中提高性能的潜力，同时承认需要进一步研究最佳配方和加工条件。

期刊介绍： Polymers (ISSN 2073-4360) is an international, open access journal of polymer science. It publishes research papers, short communications and review papers. Our aim is to encourage scientists to publish their experimental and theoretical results in as much detail as possible. Therefore, there is no restriction on the length of the papers. The full experimental details must be provided so that the results can be reproduced. Polymers provides an interdisciplinary forum for publishing papers which advance the fields of (i) polymerization methods, (ii) theory, simulation, and modeling, (iii) understanding of new physical phenomena, (iv) advances in characterization techniques, and (v) harnessing of self-assembly and biological strategies for producing complex multifunctional structures.
