本文件规定了基于激光的金属粉末床熔合（PBF-LB/M）的特点，并提供了详细的设计建议。 一些基本原则也适用于其他添加剂制造（AM）工艺，前提是充分考虑了工艺的特定特征。 本文件还通过汇集有关该工艺的相关知识，并通过扩展ISO/ASTM 52910的范围，对与粉末床熔合（PBF）使用相关的设计指南进行了最新审查。

This document specifies the features of laser-based powder bed fusion of metals (PBF-LB/M) and provides detailed design recommendations. Some of the fundamental principles are also applicable to other additive manufacturing (AM) processes, provided that due consideration is given to process-specific features. This document also provides a state of the art review of design guidelines associated with the use of powder bed fusion (PBF) by bringing together relevant knowledge about this process and by extending the scope of ISO/ASTM 52910.
