Additive manufacturing technology has the advantages of layer-by-layer rapid manufacturing, personalized manufacturing, flexible production, etc. With the advanced technology of directly manufacturing complex workpieces from computer models, it has been widely used in the manufacturing industry. The applications of additive manufacturing in aerospace and automotive fields are introduced. The advantages of additive manufacturing over traditional manufacturing in practical application and later maintenance are analyzed. Based on the advantages of additive manufacturing compared to traditional manufacturing, this paper introduces the applications of additive manufacturing technology, equipment and powder raw materials in weight reduction design and manufacturing of aerospace materials, and topology optimization and manufacturing in the automotive industry. Finally, the development status and application prospects of additive manufacturing at home and abroad are expounded, and the application of additive manufacturing technology in the manufacturing industry is predicted to increase exponentially.
