Functionally graded lattice structures for structural applications: Design, Production and performance analysis Nowadays, functionally graded lattice structures have become popular due to their low weight and high strength. Additionally, flexibility of designing various layers and orientation made them very good candidates for bone implants. In this study functionally graded lattice types Gyroid, SplitP and Diamond were constructed into cylindrical geometry. The aim was to design a lattice structure which can provide similar relative density levels with the human bone, high strength and high load carrying capacity. Functionally graded lattice samples made of AlSi10Mg are printed by selective laser melting. Functionally graded lattice structures are evaluated by conducting quasi-static compression experiments.
