【Abstract】 To leverage the light and high strength of carbon fiber materials alongside the versatility of 3D printing for enhanced printing performance of thermoplastic materials through fibre reinforcement, a path planning method for selective performance enhancement in continuous carbon fiber 3D printing was explored. This method involves segmenting the 3D model based on performance enhancement needs and providing an interface for setting process parameters in different layers and regions according to material properties. For the fill and contour regions, respective algorithms for continuous carbon fiber selective enhancement and contour enhancement with multiple mixed paths were utilized. The fiber print path in the contour region was optimized to ensure fibre path continuity, achieving flexible performance enhancement across various sections of the 3D model. The method’s effectiveness was validated through comparative simulation of 3D model path planning and experimental 3D printing results.更多还原
