Optimization of Scheme Selection for 3D Printing of Functional Objects from Composite Materials

This project explores the optimization of fiber deposition trajectories and printing scheme selection for the additive manufacturing of functional objects using continuous carbon fiber reinforced polymer composites (CFRT). In aerospace and mechanical engineering, the structural integrity and mechanical performance of composite components are highly dependent on the spatial orientation of the reinforcing fibers. Traditional manufacturing methods often limit the geometric complexity and fiber alignment control. However, 3D printing technology enables precise spatial reinforcement along customized, non-linear trajectories. This research-backed project framework provides implementation guidance for evaluating different printing path strategies, analyzing their impact on the directional mechanical properties of the printed parts. By modeling the stress distribution and aligning the

continuous carbon fibers with the principal stress vectors, the structural efficiency of the printed components can be maximized. The project outlines a systematic methodology for selecting optimal printing schemes based on structural requirements, utilizing computational path planning and finite element analysis (FEA) to validate the mechanical performance. This study serves as a technical reference for students seeking to develop advanced manufacturing workflows for high-performance composite structures.
