ASTM F3281-19

 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.
