Zusammenfassung:The invention provides a continuous fiber composite material global breakpoint-free 3D printing path planning method based on component structure feature distribution connection points. On the basis of discretized structural features, an intra-layer breakpoint-free 3D printing path is obtained by offsetting a contour line and adopting an intra-layer adjacent path cross bridge connection strategy; meanwhile, a connection point in-layer distribution strategy is adopted, and a connection point intra-layer distribution mode which does not affect the performance of the component is determined according to the structural features of the component; on the basis, interlayer paths are connected through a space curve, and a global breakpoint-free path of the component is obtained; in combination with the structural features of the component, a connection point interlayer distribution strategy is adopted to determine a connection point interlayer distribution mode, so as to further reduce the influence on the performanc
