多材料增材制造研究现状及展望

With the continuous improvement of the performance requirements of components for high-end equipment, for example, different positions of a component need to achieve high strength, high toughness, high thermal conductivity, and corrosion resistance respectively, additive manufacturing urgently needs to break through from a single material structure to a multi-material structure, and multi-material additive manufacturing oriented to the optimal performance of components has also become a research hotspot. According to the classification of major additive manufacturing materials, the technical principles, construction and optimization of forming systems, and macro and micro characteristics of material bonding interfaces for polymer, metal, and ceramic multi-material additive manufacturing are respectively summarized; the applications of multi-material additive manufacturing technology in fields such as biomedical and electronic circuits are introduced; the future development directions and research priorities of multi-material additive manufacturing are pointed out.
