Current Status of Research on Multi-axis FDM Additive Manufacturing for Mechanical Property Enhancement

Recent advancements in multi-axis printing and composite materials have shown promise in addressing these issues, but systematic studies on the synergistic effects of material enhancement and chunking optimization remain scarce.Therefore, this research aims to bridge this gap by integrating highperformance composites with advanced multi-axis chunking strategies to achieve superior mechanical performance and functional versatility.This paper investigates how to improve the mechanical properties by both material preference and chunking optimization in multi-axis FDM technology.In terms of materials, high-performance composites such as nano-reinforced plastics and bio-based materials are used, combined with a melt blending process to enhance strength.In the printing technology, the multi-axis chunking strategy dynamically adjusts the deposition direction, optimizes the path planning and support structure, enhances the interlayer bonding and reduces the anisotropy.Process parameter adjustment in the fiber orientation of the enhancement of the planning path, multi-material interface, combined with optimization to break through the single material performance limitations.Future research directions include intelligent material design, multi-material synergistic printing and sustainable development paths to promote the application of high-performance additive manufacturing in aerospace, medical and other fields.
