本文件规定了基于激光的聚合物粉末床熔合（LB-PBF/P）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扩展ISO/ASTM 52910的范围，对与粉末床熔接（PBF）使用相关的设计指南进行了最新的审查。

This document specifies the features of laser-based powder bed fusion of polymers (LB-PBF/P) 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.
