Additive Manufacturing (AM) opens new horizons and paradigms for design, manufacturing and even tertiary activities. However, the quality of built parts in terms of mechanical properties, surface texture, geometrical and dimensional accuracy, remains highly dependent not only on AM systems' parameters, but also on the chosen process among the numerous available AM processes. Therefore, to control the quality of built parts, it is essential to evaluate the influence of each process-related and system parameter. This can be done by building meta-models for the prediction of printed parts' output properties or through experimentations using artefacts. Another approach consists in pure analytical modelling of AM processes and systems based on physics and thermo-mechanical phenomena occurring during the build phase. Finally, there are hybrid compensation models based on process physics analysis and experimentations using artefacts. In all of the aforementioned methods, AM artefacts are crucial to predict, build and validate models. However, essentially due to a lack of systematic design guidelines, several proposals for standardised AM artefacts ended up unsuccessfully. By taking advantage of concepts and tools of axiomatic design, this work introduces a detailed and systematic design approach for customised AM artefacts. A case study is also detailed and discussed.
