Abstract
Material extrusion is one of the most widespread additive manufacturing processes because of its low-cost implementation and its flexibility in design. In this study, integrated digital image correlation is used for the identification of constitutive parameters of two configurations of acrylonitrile butadiene styrene (ABS) samples. It is shown that an isotropic elastoplastic model calibrated from one single edge notched tension specimen described correctly the behavior of 3D printed ABS parts independently of the internal infill strategy. • Material parameters were calibrated from single SENT specimen via I-DIC in anisotropic elasticity. • The impact of elastic anisotropy of printed layers on the mechanical response is quantified. • Isotropic elastoplastic model calibrated from one single SENT specimen described the behavior of 3 printed ABS parts.
