• In this paper, the consolidation of an experimental approach for the evaluation of the mechanical properties of FDM (Fused Deposition Modelling) 3D printed objects is proposed. ASTM standards addressed to polymers were adapted to FDM 3D printed specimens in order to derive a complete mechanical characterization of PLA (PolyLactic Acid). The tensile test aimed to the determination of the in-plane mechanical properties of pseudo-isotropic specimens. The compression test allowed the evaluation of the out-of-plane mechanical properties of 3D printed parts. The three-point bending test on sandwich specimens helped to assess the not studied potential of FDM in the production of complex and integrated structural elements. The quantitative results show that this common, non-structural, environmentally friendly polymer can be successfully employed to produce customized and integrated structural elements for non-critical operating environment.
