【Abstract】 Die and mold play the important role in modern industrial production, and the appearance and industrialization of additive manufacturing technology has brought changes to the die and mold industry. In this paper, the main additive manufacturing technologies applied in die and mold industry, including binder jetting,selective laser sintering, selective laser melting and stereo lithography appearance, are briefly introduced. At the same time, according to two typical application fields of additive manufacturing technology, namely “mold rapid prototyping manufacturing” and “high performance parts manufacturing”, the specific application methods of additive manufacturing technology were analyzed, and the relevant research results at home and abroad were summarized. Finally, the key problem to be solved in the mass application of additive manufacturing technology in die and mold industry is “how to improve the cost performance of additive manufacturing technology compared with traditional manufacturing technology through the study of raw materials, process and equipment”,and the future development of additive manufacturing technology in the mold industry is prospected.更多还原
