| Abstract Scope |
Lattice-structured lightweight materials fabricated via Laser Powder Bed Fusion (LPBF) are promising for advanced energy systems, including fission batteries and small molecule reactors, where weight reduction and structural integrity are critical. This study investigates the influence of lattice design parameters—such as unit cell size, blend radius, relative density, solid shell thickness—and lattice topology on the tensile behavior of LPBF-manufactured components. A combination of computational modeling and tensile testing was employed to evaluate the performance of various lattice parameters and architectures. Among the parameters studied, relative density emerged as the dominant factor affecting tensile properties, and the unit cell size of lattice has a minimal effect. Gyroid structure with 70% relative density exhibited tensile performance comparable to wrought materials, offering substantial weight savings without compromising structural strength. These results highlight the potential of engineered lattice designs for enabling compact, efficient, and mechanically robust components in next-generation energy systems. |
