This document describes the capabilities and responsibilities required for the qualification of the operators on the field of the Additive Manufacturing technologies dealing with metallic parts production, specifically for the employment of powder bed fusion laser beam with metals (PBF-LB/M). This document defines criteria for the theoretical and practical assessment of personnel operating PBF-LB/M machines. The activities and procedures foreseen to be performed by the PBF-LB/M operator are also part of the standard. This document is intended to provide an outline for qualification of machine operators in general industrial applications. Where industry-specific requirements exist for the qualification of operators, such as ISO/ASTM 52942 for aerospace applications, those industry-specific standards shall be used instead of this document.
