Abstract

Abstract It is known that the strain rate affects significantly the mechanical properties of the engineering materials. The aim of this study is to investigate the effect of the cross-head speed on the mechanical properties of acrylate and methacrylate-based oligomer/monomer materials of the specimens produced by Stereolithography (SLA) printer. The characteristic mechanical properties of materials, such as modulus of elasticity, Poisson’s ratio, and the ultimate strength depending on low strain rate levels were explored. The fractured surfaces of the tensile test specimens were examined by Scanning Electron Microscopy (SEM). Based on the experimental results, it is concluded the mechanical properties of the photosensitive resins are quite sensitive to the tensile test speeds.
