Compressive properties of cuttlebone-like lattice (CLL) materials with functionally graded density

Complex and small-scale architectures, e.g., topology-optimised materials and functionally graded lattice materials (FGLMs), can be well fabricated with the assistance of additive manufacturing (AM). This work investigates the compressive properties of a functionally graded cuttlebone-like lattice (CLL) material. Experimental compression tests are performed on both uniform and graded lattice materials, which are made of Inconel 718 via selective...
