Increased customization and design freedom, decreased waste, quicker prototyping, and the creation of challenging profile forms are all made possible by additive manufacturing (AM)8. In 3D printing, the printing parameters have a direct impact on the mechanical strength of the final product. This study examined the impact of various infill configurations (Grid, Rectilinear, Honeycomb), infill densities (15 %), and material (PLA, PETG) and layer thickness (0.1 mm, 0.2 mm) in that sequence. According to experimental research, at every infill pattern and layer thickness, the honeycomb infill pattern exhibits a higher tensile strength than the grid and rectilinear infill pattern. The tensile strength of honeycomb infill geometry is stronger when the layer thickness is 0.1mm,
