scope:

This document defines the methodology for generic AM-machine evaluation in automotive environment using objective test criteria and provides the framework for an objective AMmachine evaluation and comparison. This document finds application in benchmarks, preparation of purchase decisions, but also AM-machine evaluation within the machine procurement, acceptance, and qualification process. The methodology and performance characteristics are introduced to enable evaluation on an objective and quantitative basis. The documentation resulting from the AM-machine evaluation is used to obtain a reliable orientation selection and evaluation of PBF-LB/M AM-machines. Furthermore, this document specifies machine KPIs in the context of machine procurement, production planning and production of PBF-LB/M components. It aims to reach a detailed understanding between machine supplier and machine customer with respect to the acceptance criteria during the procurement process and evaluation of machine performance during running production. This document is applicable to the additive manufacturing technology LPBF-M defined in ISO/ASTM 52900.
