1.1 本文件为考虑在其产品中使用金属激光粉末床熔合（PBF-LB）方法的设计师提供了指导。本指南概述了金属添加剂制造系统构建完成后可以考虑的以下后处理操作: 1.1.1 粉末去除， 1.1.2 热后处理， 1.1.3 建造平台拆除， 1.1.4 支架拆除， 1.1.5 机械加工，以及 1.1.6 表面修整。 1.2 无损检测（NDT）和检验主题超出了本文件的范围，因为它本身需要一个全面的指南。 此外，范围外还有其他金属PBF工艺，如粉末床熔合-电子束（PBF-EB）和混合添加剂制造（在一台机器中结合添加剂制造和减法制造技术的方法）。 1.3 关于现有的ISO/ASTM标准，本指南位于ISO/ASTM之间 52910 和工艺特定设计指南，如ISO/ASTM 52911-1 . 1.4 本标准并非旨在解决与其使用相关的所有安全问题（如有）。本标准的用户有责任在使用前制定适当的安全、健康和环境实践，并确定监管限制的适用性。 1.5 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 provides guidance to designers who are considering the use of metal Laser Powder Bed Fusion (PBF-LB) method for their products. This guide outlines the following post-processing operations that can be considered after completion of a build on a metal additive manufacturing system: 1.1.1 Powder removal, 1.1.2 Thermal post-processing, 1.1.3 Build platform removal, 1.1.4 Support removal, 1.1.5 Machining, and 1.1.6 Surface finishing. 1.2 The topics of non-destructive testing (NDT) and inspection are beyond the scope of this document as it requires a comprehensive guide in its own right. Also, outside the scope are other metal PBF processes such as powder bed fusion – electron beam (PBF-EB) and hybrid additive manufacturing (methods combining additive manufacturing and subtractive manufacturing technologies in a single machine). 1.3 With respect to existing ISO/ASTM standards, this guide is positioned between ISO/ASTM 52910 and process-specific design guidelines such as ISO/ASTM 52911-1 . 1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use. 1.5 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.
