Continuous Fiber Reinforced Composites (CFRCs) are ex-tensively employed in advanced industries such as aero-space and rail transit, owing to their superior mechanical properties. In recent years, additive manufacturing (3D printing) has emerged as a primary method for fabricating CFRCs, eliminating the limitations of traditional manufac-turing processes that rely on molds. This review provides a comprehensive overview of the latest advancements in pre-dictive modeling of CFRCs additive manufacturing, cover-ing the entire technological development pathway from process modeling to structural mechanics modeling of 3D printed CFRCs. The section on process modeling of CFRCs additive manufacturing explores key aspects such as resin flow and infiltration behavior, heat transfer mechanisms, residual stress evolution, and fiber misalignment control. The subsequent section on structural mechanics modeling of 3D printed CFRCs presents mainstream modeling approach-es at the micro, meso, and macro scales, highlighting their application scenarios. It also examines the potential of mul-tiscale modeling techniques, which bridge these different scales to enhance predictive accuracy. Finally, this review systematically identifies the major challenges currently faced in predictive modeling of CFRCs additive manufac-turing and outlines future research directions. These insights provide theoretical guidance and technical support for ad-vancing the scientific understanding and practical applica-tion of high-performance CFRCs in additive manufacturing.
