The goal of the current study is to make the materials used to make Ornithopter unmanned aerial vehicles as efficient as possible (UAV). PTC Creo was used to model the ornithopter gearbox's 3D model. The 3D printing process is used to create the modeled gearbox. The literature is used to provide the calculations needed for the gearbox's design. The gearbox experiences extremely high loads and strains while flapping, hence methods other than 3D printing are being investigated in the field of additive manufacturing. PLA, TPU, PLA+, Nylon, ABS, and Carbon fiber are among the materials that were taken into account for the comparison analysis. All materials exhibit identical flapping speeds up to 4 Hz frequency, but after that frequency, the materials act differently. The investigation came to the conclusion that carbon fiber is a superior material to other materials. A CNC machine is used to prepare carbon fiber for the gearbox frame and the flaps. Future assembly and examination of the carbon fiber components for flapping mechanisms are possible.
