In this work, the applicability of the Theory of Critical Distances to the study of failure at high-loadings rates of polyamide 12 notched specimens additively manufactured by selective laser sintering, is evaluated. An experimental and numerical study has been carried out and values of modulus of elasticity, tensile strength and fracture toughness have been obtained. under static and dynamic conditions. The effect of orientation has also been analyzed, testing samples parallel and perpendicular to the layers of material deposited.
