キーワード：3D Printing, Lattice Structures, Zirconia Ceramics, Nanoparticle Jetting, Controlled Porosity
Motivated by the imperative to meet diverse performance requirements in force, heat, sound, and beyond, this study explores the integration of micron-level to centimeter-level lattice structure units into zirconia ceramics through advanced nanoparticle jetting. Through meticulous adjustments in both the 3D printing and sintering processes, we systematically control the porosity of constituent rods within these lattice structures. Diverse lattice designs are strategically implemented to optimize mechanical properties along the loading direction, addressing the pressing need for structure-function integration. Notably, the development of a compression-resistant lattice structure results in a material boasting exceptional specific strength, surpassing that of the base material by a factor of two. This research not only introduces a pioneering approach to lattice architectures but also demonstrates unprecedented controllability, providing valuable insights for the design of advanced lightweight, high-strength materials with multifaceted engineering applications.
