Abstract

To enhance the comprehensive performance and forming quality of 3D printed parts, a conformal five-axis 3D printing process was proposed for continuous carbon fiber reinforced composites on curved surfaces. Utilizing a self-designed and constructed five-axis dual-nozzle 3D printing platform and print path planning, typical specimens with a sandwich structure format and curved surface specimens were printed using continuous carbon fiber as the reinforcement material, polylactic acid (PLA) as the matrix material, and polyvinyl alcohol (PVA) as the support material. Mechanical performance tests were conducted on the printed typical specimens and curved surface specimens, and comparisons were made with specimens lacking the sandwich structure format. The experimental results indicated that both the mechanical properties and surface quality of the typical specimens and curved surface specimens printed using this process were enhanced. In conclusion, it is demonstrated that the conformal five-axis 3D printing process for continuous carbon fiber reinforced composites, realized through this five-axis dual-nozzle printing platform, could effectively improve the comprehensive performance and forming quality of 3D printed parts.

Key words： five-axis 3D printing; continuous carbon fiber reinforced composites; dual-nozzle; conformal printing
