Additive manufacturing of metals has opened a whole new range of complex functional geometries inaccessible by convectional production methods which are called to revolutionise several sectors (i.e., biomedical, aerospace, energy). These parts usually include a wide variety of characteristic elemental length scales from thin walls/struts to bulk regions. The different intrinsic aspects of the manufacturing process (heat fluxes) make the properties of the material strongly size dependent. These dependencies are still unclear, and further investigations are needed in order to ensure the quality of the produced parts. In this work, the variation of the mechanical properties as a function of the component size and build orientation is addressed.
