Experimental investigation on mechanical characterization of 3D printed PLA produced by fused deposition modeling (FDM)

Abstract This study aims to systematically experimental investigate the influence of infill-patterns (IPs) on specific mechanical responses parts fabricated by fused deposition modeling (FDM). A poly-lactic-acid (PLA) feedstock filament is utilized in manufacturing process. Furthermore, six types (deposition angle), namely full honeycomb, rectilinear, triangular, fast grid, and wiggle, are designed printed. In order determine properties manufactured parts, tensile tests carried out. The such as extension, stress, elongation, energy, Young’s modulus considered objective functions. As a result, there direct correlation between infill patterns. Thus, it essential select best infill-pattern terms their applications, giving sufficient strength without overdoing time cost. Based results, triangular has maximum value ultimate E-module (15.4 534 MPa, respectively). On other hand, wiggle pattern more flexible.
