Comparison of the effect of different topological designs and process parameters on mechanical strength in gears

Gear wheels, the first examples of use in the Mesopotamian period, continue to develop with different forms and features together with advanced technologies. Within the scope of this study, the DMLS (direct metal laser sintering) technique, which is one of the latest technologies, was preferred as a method in the production of gears. A total of four different samples, including gears designed as hexagonal, radial, and gyroid lattice designed as lightweight, and gears using porous structure obtained with the DMLS hatch distance parameter, were compared in terms of mechanical strength. The tooth-breaking behaviors of the models tested in the physical test setup specially designed for the study were examined by SEM (scanning electron microscope), and the results were shared.
