“…This mechanism has been attributed to material softening due to damage accumulation and to the occurrence of high-dimension defects. Similarly, Nizina et al, [49] found a significant variation in the stress-strain curve of the sample characterized by the presence of structural defects. All results are referred to the sample 1 but similar results have been obtained for the second one.…”

3D printing is a widespread technology in different fields, such as medicine, construction, ergonomics, and the transportation industry. Its diffusion is related to the ability of this technique to produce complex parts without needing for assembly of different components or post-processing. However, the quality of the parts produced by additive manufacturing could be affected by the fabrication process, thus leading to the development of different kinds of defects such as porosity or inclusions. Understanding the role played by these defects and promoting strategies that could help reduce their occurrence represents a key point to allow using 3D printing for structural applications. In this work, 3D printed parts have been subjected to porosity characterization by using experimental tests on Dogbones samples subjected to plastic deformation. In particular, X-ray computed micro-tomography (µ-CT) has been employed as an investigation tool for the identification of fabrication defects and for analyzing the crack growth mechanism that occurs after subjecting samples to quasi-static loading conditions.
