The invention discloses a typical path planning method for 3D (three-dimensional) printing of continuous fiber reinforced composites and belongs to the field of rapid prototyping of the composites. Inthe method, a three-dimensional model is built by using CAD (computer aided design) modeling software according to actual size requirements of forming components and is subjected to slice stratification by the aid of the three-dimensional software to acquire profile and slice information; the degree of path bending is judged and corresponding path planning mechanisms are started, and with the help of the jump point processing mechanism, jump points can be accurately located and the action of the jump points is completed; fiber interlayer conversion without breakpoint is realized by using an interlayer path planning mechanism, and high quality and high efficiency three-dimensional printing new path of the continuous fiber reinforced composites is realized. In the method, the printing pathwith the least breakpoints is planned out, and mechanical property of the continuous fiber reinforced composites is guaranteed; forming defects in the bending of continuous fiber are effectively reduced, binding force of the continuous fiber in the bending is improved, and integral performance of the forming components is improved.
