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