Rationale

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.
