In this review paper, recent developments in the Fused Filament Fabrication (FFF) approach are provided for composite materials. Influencing parameters in FFF process such as road width, print speed, layer thickness, feed rate and build temperature of the model (both liquefier and envelope temperature), fiber orientation, the layer position, volume fraction, and infill orientation have been studied. These considered parameters in the strength/bonding or physicochemical characterizations of FFF-fabricated parts have been presented in detail. An overview of the mechanical properties of printed parts for different composite material systems is presented and discussed. Three types of reinforced polymers in FFF process have been considered: filled reinforced polymers, continuous fiber-reinforced polymers, and short fiber reinforced polymers.

在这篇评论论文中，提供了用于复合材料的熔融长丝制造 (FFF) 方法的最新进展。已经研究了 FFF 过程中的影响参数，如道路宽度、打印速度、层厚度、进料速率和模型的构建温度（液化器和包络温度）、纤维取向、层位置、体积分数和填充取向。详细介绍了 FFF 制造部件的强度/粘合或物理化学特性中的这些考虑参数。概述并讨论了不同复合材料系统的打印部件的机械性能。FFF工艺中考虑了三种类型的增强聚合物：填充增强聚合物、连续纤维增强聚合物和短纤维增强聚合物。
