摘要整理
熔融沉积成型(FDM)是一种快速发展的增材制造技术，能够在短时间内制造复杂形状的零件。该技术通过逐层堆积轮廓层来实现所需形状的制造。由于成本低、设计灵活性高和制造过程自动化等优势，FDM技术在工业中得到广泛应用。然而，FDM打印件的力学性能仍低于传统制造产品。为改善FDM打印件的力学性能，研究人员采用纤维增强聚合物基体的方法，这不仅能提高力学性能，还能增强热性能和电性能。本综述重点阐述了FDM 3D打印纤维增强聚合物复合材料的纤维类型和纤维植入工艺。首先介绍了熔融沉积成型、聚合物烧结及FDM打印过程中的孔隙形成机制；其次阐述了纤维增强聚合物复合材料的基础理论、纤维类型(合成纤维vs.天然纤维、连续纤维vs.非连续纤维)及复合材料性能；最后重点评述了三种基于纤维植入时间和位置的纤维增强热塑性复合材料制造方法，即'打印前植入(M1)'、'喷嘴内植入(M2)'和'零件表面植入(M3)'，并讨论了三种工艺制备的复合材料性能差异。
