© 2021 The American Ceramic SocietyWe report on the fabrication of a complex gear–shaped 3 mol.% yttria–stabilized zirconia via a combination of additive manufacturing and flash sintering. The gear was printed via direct ink printing technique. Flash sintering was performed at an electric field of 150 V/cm and the specimens were rapidly densified within a few seconds at a furnace temperature of 1200°C. The flash–sintered gear has a 95% relative density and shows no obvious warping or cracking after the rapid densification. Microstructure analysis and hardness measurement revealed grain size gradients and hardness variation along both thickness and lateral directions of the flash–sintered gear. This study demonstrates a possible route to produce dense complex–shaped parts using the flash sintering technique.
