Computational characterization of polymeric materials 3D-printed via fused filament fabrication

Abstract: This work develops a novel homogenization-based computational strategy for predicting the mechanical properties of Fused Filament Fabricated parts by characterizing the component according to the different printing patterns used. The anisotropic constitutive material models obtained for each printing pattern allows the accurate prediction of the behavior of the entire component.The model is validated against experiments with the samples manufactured according to corresponding printing patterns. Various materia… Show more

“…The in-fill structure is modelled as a homogeneous medium with an equivalent constitutive behaviour [28]. It is convenient to use RVE-based homogenization [29][30][31] since the heterogeneities in the in-fill present periodicity over the domain and the structure is characterized by the repetition of a unit cell [32][33][34].…”
