Additive manufacturing for automotive — Qualification principles — Generic machine evaluation and specification of key performance indicators for PBF-LB/M processes

1.1 This document specifies the methodology for generic AM-machine evaluation in automotive environment using objective test criteria and provides the framework for an objective AM-machine evaluation and comparison. This document finds application in benchmarks, in the preparation of purchase decisions, but also in AM-machine evaluation within the machine procurement, acceptance, and qualification processes. This document is specific to automotive, as it is related to existing series part requirements of various original equipment manufacturers, but the content can be transferred to other industries if necessary.

1.2 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 user with respect to the acceptance criteria during the procurement process and evaluation of machine performance during running production. For using this document, all process parameters, such as scanning speed, laser power, etc., are fixed, since changing these parameters can affect the entire process performance and its stability. Therefore, variables are not changed any more during or after qualification. This document and the determination of the KPIs help in the evaluation of machine properties, but do not replace an application-specific approval process.

1.3 This document is applicable to the additive manufacturing technology PBF-LB/M.

1.4 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
