Additive manufacturing of metals - Powder bed fusion - Classification of imperfections (ISO/ASTM 52948:2026)
Abstract
This document specifies the classification of imperfections possibly generated during an additive manufacturing process by PBF-LB (laser beam powder bed fusion) or PBF-EB (electron beam powder bed fusion) for metallic parts. This document also indicates the most probable causes of the formation of imperfections and includes illustrations. This can be extended to other additive manufacturing process categories, nevertheless, the indication of probable causes is process specific. Acceptance criteria and dimensional description or scale for imperfections are not included in this document.
