Research on the application of metal additive manufacturing technology

金属材料增材制造技术作为3D打印应用的重要方向之一,已经有30多年的发展历程,相比传统加工制造方式具有周期短、效率高、节约材料以及特别适合成形复杂零件等优点。首先介绍了金属材料增材制造技术的基本原理和发展历程,列举了世界各国在3D打印技术领域推出的发展规划和技术规范,简述了金属材料增材制造在国内外应用研究现状及其取得的成果,最后指出金属材料增材制造技术需要在金属粉末、零件表面质量、成形尺寸、国际标准等方面进行重点研究。

Metal additive manufacturing technology is an important direction of 3 D printing,which has been developed for more than 30 years. Compared to traditional forming methods,it is more desirable in terms of time,efficiency,economy,and it is especially suitable for forming complicated parts. The basic principles of metal additive manufacturing,policies made worldwide,and progresses achieved by researchers at home and abroad were reviewed. It was also pointed out that metal additive manufacturing technology should solve problems such as metal powder,surface quality,forming size and international standard in order to make breakthroughs.
