ISO/ASTM DIS 52948

Additive manufacturing for metals — Non-destructive testing and evaluation — Imperfections classification in PBF parts

Scope

This document specifies a classification of the imperfections likely to be generated during an additive manufacturing operation by PBF-LB (laser beam powder bed fusion) or PBF-EB (electron beam powder bed fusion) for metal parts. This document also indicates the most probable causes of the formation of imperfections and gives some illustrations taken from feedback.

NOTE This classification applies to both PBF-LB and PBF-EB processes and can be extended to other additive manufacturing processes.
