ASTM WK90673
New Specification for Additive manufacturing for metals - Non-destructive testing and evaluation - Imperfections classification in DED parts
1. Scope
This document specifies the classification imperfections likely to be generated during an additive manufacturing process by DED for metallic parts. This document also indicates the most probable causes of the formation of imperfections and includes illustrations. Acceptance criteria for imperfections are not included in this document.Keywords

Directed Energy Deposition (DED) additive manufacturing (AM) using a laser (DED-LB), an electron beam (DED-EB) or an arc (DED-Arc) is in full development. It is thus possible to produce parts of small to large dimensions with a moderate complexity. The control of this process is the subject of numerous studies in order to guarantee the best possible quality. It is essential to supplement these approaches with a standard describing observable defects to serve as a basis for Non-Destructive Testing (NDT). Knowledge of the defects generated by the manufacturing process and their standardized classification are preliminary and essential steps in defining and applying acceptance criteria for non-destructive testing. This work will bring together new and existing information into a single comprehensive standard document. This document is being jointly developed with ISO TC261 per the ASTM/ISO PSDO. Once approved, it will carry the designation ISO/ASTM52969.
