摘要：

Additive manufacturing of continuous carbon fiber reinforced plastic composites (C-CFRP) has raised considerable interest. Developing continuous printing trajectories to improve the mechanical properties of the as-built parts is of great significance. However, myriad jumping paths and gathered connection paths occur in the existing printing strategies causing inferior part quality. In this study, we present a novel continuous printing strategy to avoid jumping paths and achieve the unique dispersion of connection paths. Tensile and three-point bending tests are conducted to verify the enhanced mechanical performance. This work enables us to eliminate the cutting mechanism in the commercial C-CFRP printers.
