1.1 本文件规定了定向能沉积（DED）的特点，并提供了详细的设计建议。本文件还通过汇集有关此过程的相关知识并扩展ISO/ASTM 52910的范围，对与DED使用相关的设计指南进行了最先进的审查。 一些基本原则也适用于其他添加剂制造（AM）工艺，前提是适当考虑了工艺的特定特征。 1.2 本国际标准是根据世界贸易组织技术性贸易壁垒（TBT）委员会发布的《关于制定国际标准、指南和建议的原则的决定》中确立的国际公认标准化原则制定的。

1.1 This document specifies the features of Directed Energy Deposition (DED) and provides detailed design recommendations. This document also provides a state-of-the-art review of design guidelines associated with the use of DED by bringing together relevant knowledge about this process and by extending the scope of ISO/ASTM 52910. Some of the fundamental principles are also applicable to other additive manufacturing (AM) processes, provided that due consideration is given to process-specific features. 1.2 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
