本文件规定了聚合物激光粉末床聚变（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）过程，前提是适当考虑了过程的特定特征。本文件还通过汇集有关该工艺的相关知识和扩大ISO\/ASTM 52910的范围，对与使用粉末床聚变（PBF）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.
