| Abstract Scope |
Laser Powder Bed Fusion (LPBF) process, a metal additive manufacturing technique, has made it possible to create lightweight and intricate porous metal structures that have practical applications in areas such as aerospace and medical devices. Some of the difficulties faced in the fabrication of highly complex stochastic/non-stochastic structures via conventional manufacturing techniques can be bypassed using the LPBF process in spite of its limitations in terms of geometric accuracy. One advantage of LPBF is that it enables the creation of non-random structures, known as TPMS structures, which have a good combination of stiffness and high surface-to-volume ratio. The properties of the manufactured structures can be altered by adjusting the unit cell structure and relative density. Functionally graded samples such as gyroid, primitive, diamond, and neovius were fabricated from 316L, heat-treated, and analyzed to examine the effect of various lattices on both manufacturability and mechanical properties. |
