<abstract>金属增材制造技术作为3D打印 技术的一个重要分支，在20余年的发展中取得了显著的进展。文中简要回顾了金属增材制 造技术的历史溯源，重点从制件组织结构、制件性能、制件微观缺陷、成形工艺等方面分析 了针对钛合金、镍基高温合金等常用材料的增材制造技术研究新进展，探讨了增材制造技术 发展所面临的技术问题以及需要重点考虑的发展方向。</abstract>
<en_abstract>The metal additive manufacturing technique， as an importan t branch of 3D printing technique， has made remarkable progress based on the rapid development of materials technique， equipment technique， computer techniq ue， and so on. The evolution history of metal additive manufacturing technique i s reviewed briefly. The microstructure， the me chanical performance， the micro defect， and the technological process of product are introduced to discuss the studies on additive manufacturing technique of titanium allo y， nickel base superalloy， and so on. Some suggestions of technical problems in the development of additive manufacturing technique are put forward. Finally， the main development direction is pointed out.</en_abstract>
