On elastic anisotropy of 3D printed acrylonitrile butadiene styrene structures

Material extrusion is one of the most widespread additive manufacturing processes because its low-cost implementation and flexibility in design. In this study, integrated digital image correlation used for identification constitutive parameters two configurations acrylonitrile butadiene styrene (ABS) samples. It shown that an isotropic elastoplastic model calibrated from single edge notched tension specimen described correctly behavior 3D printed ABS parts independently internal infill strategy.
