RESEARCH ON PERFORMANCE BOTTLENECKS AND SOLUTION STRATEGIES FOR ADDITIVE MANUFACTURING MATERIALS
ABSTRACT
Additive manufacturing technology (AM or 3D printing) has become a hotspot in manufacturing research due to its unique concept and application prospects. This technology enables direct manufacturing by adding materials layer by layer, simplifying the production process and shortening the design to manufacturing cycle. Despite its advantages, material performance bottlenecks such as strength, toughness, thermal stability, corrosion resistance, and fatigue properties limit their development. This paper studies these problems in depth and proposes solutions, such as optimizing material formulation, improving processing technology, application of heat treatment techniques, development of new anticorrosive materials and surface reinforcement techniques to effectively improve material properties. Research shows that these strategies significantly improve parts performance and broaden the scope of AM technology applications, especially in high-end manufacturing areas. This paper provides theoretical and practical guidance for the optimization of AM material properties and lays the foundation for technological development.
