Abstract: Additive manufacturing can produce the arbitrary complex shape parts, which has the advantages of fast, efficient, economical, fully intelligent, and fully flexible manufacturing. Based on the introduction of the typical metal additive manufacturing technology at home and abroad, the application of the metal additive manufacturing technology in the field of nuclear industry was overviewed in this paper, the performance of nuclear material products prepared by the additive manufacturing was summarized, and the advantages of the metal additive manufacturing in the field of nuclear industry were proved by the practical cases. At the same time, the development trend of the additive manufacturing technology in the field of nuclear materials was forecasted based on the application background of the innovative reactor technology for the nuclear materials.
