However, from the practical point of view, it seems to be incorrect to attribute the better mechanical properties resulted from a higher aspect ratio to its building orientation, since it is also possible to have a vertical specimen with the same aspect ratio in comparison to its horizontal counterpart, as shown in Fig. 7. This case might be quite common in industrial applications where, instead of standard test specimens, actual parts are manufactured via SLM. Thus, relating the aspect ratio to the building direction is a delusive conclusion. A better approach is to consider the aspect ratio as an independent manufacturing parameter and study it as a basic processing factor. It is also feasible to change the scanning speed according to the aspect ratio to keep the thermal gradients uniform throughout the geometry of the part
