Development of the Additive Manufacturing(3D printing)Technology

Additive Manufacturing technology,Commonly known as the 3D printing technology,is one of the advanced manufacturing technology which has developed rapidly in recent 30 years.It is adept at rapid and free-forming fabrication of 3D structures and widely used in new products development and single-piece or small-batch production.The development state of additive manufacturing(3D printing) systems and applications both at home and abroad are introduced,and the development trends and key technologies in the future are discussed in this paper.
