exhibit a very peculiar ductile behavior with dimples

of nanometric thickness.

From the experimental results it is concluded that

both the orientation and the post-processing condition

of the part affect the final mechanical properties.

Especially, it is confirmed that the properties are

uniform in the deposition (XY) plane, whereas there is

evidence of some anisotropy in the building direction

(Z-axis). The anisotropy is due to the nature of the

process, that creates parts by joining ...
