摘要：

The present paper analyzes manufacturing density effect on the mechanical properties of three-dimensional (3D) printed ABS specimens. Indeed, the optimum density of the printed specimens is investigated to reach the extruded specimens' characteristics. Then, the mechanical properties such as the tensile strength, the Young's modulus, the ultimate tensile and yield strength, the ductility and fracture toughness are identified and compared. Furthermore, we study crosshead speed effect on printed samples with an infill rate of 100% towards crack propagation. Subsequently, the stress intensity factor is determined. The results indicate a considerable effect of the density and the filling rate on tensile properties and on the rupture propagation. (C) 2020 The Authors. Published by Elsevier B.V.
