FDM is a method of fabricating parts by depositing successive layers of material in accordance with computer-aided design file. The properties of the finished products manufactured with FDM are sensitive to the process parameters used. Most FDM items still lack adequate mechanical characteristics when compared to those produced using conventional methods. This investigation seeks to address this knowledge gap by fabricating tensile specimens from Polyethylene Terephthalate Glycol (PETG) filament in a variety of geometries, including grids, octets, triangles, and hexagons. To verify this claim, samples studied was printed with varying infill percentages (25, 50, 75, and 100) % to see how this impacted the mechanical characteristics such as tensile strength and fractured strain. Although the best results for tensile stress and hardness were achieved with a 100% infill percentage in all four printing situations, the triangles orientation consistently produced the best results.
