On elastic anisotropy of 3D printed acrylonitrile butadiene styrene structures

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.

Automated summary

This study uses integrated digital image correlation to identify the constitutive parameters of two configurations of ABS samples and shows that a calibrated isotropic elastoplastic model can accurately describe the behavior of 3D printed ABS parts with different internal infill strategies.
