The additive manufacturing, as a revolutionary manufacturing method, has achieved remarkable results. The research was to overview the wide applications of additive manufacturing technology on different materials and components, while deeply analyze its cutting-edge research in multiple fields, and provide useful references for the research and practice in related fields. In terms of multi-material applications, the applications of additive manufacturing technologies were discussed on different materials such as metals, polymers and ceramics. In the area of metal materials, technologies such as laser melting and electron beam melting provided new ways to manufacturing high-strength and lightweight metal parts. As for polymers, biocompatible materials were widely used in fields such as medical implants and bioprinting. The additive manufacturing of ceramic materials, on the other hand, provided innovative solutions for the manufacturing of high-temperature and corrosion-resistant parts. Then additive manufacturing technologies was applied to different components, such as the lightweight parts manufacturing in the aerospace field and personalized implants in the medical device field. Meanwhile, automobile manufacturing, electronic devices, packaging materials and other fields also ushered in more efficient and flexible production methods driven by additive manufacturing. With the continuous progress of material science and manufacturing technology, additive manufacturing will be more widely used in various industries , further promote the innovation and development of manufacturing industry.
