dc.description.abstractThe work in this thesis paper quantifies the mechanical property, fracture toughness (GIC), of 3D printed polylactide acid (PLA) specimens. The established data of fracture toughness were obtained using the DCB method for interlaminar unidirectional fibers per reference [2]. Testing is broken into six groups of the same overall geometry with varied printing settings, labeled A-F. Group A has an extrusion temperature of 205 ℃ and extruded layer height of 20 mm. Groups B, C, and F have the same extrusion height with temperatures of 200 ℃, 195 ℃, and 190 ℃, respectively. All Groups are similar in the overall dimension. Groups D and E have temperature of 205 ℃ and the extruded layer heights of 30 mm and 40 mm, respectively. Groups A through F are compared to each other with Group D exhibiting the highest GIC of 10.626 $(KJ/m^2)$. In contrast, Group E has the lowest GIC of 0.934 $(KJ/m^2)$.
