| Abstract Scope |
In metal Additive Manufacturing (AM), AlSi10Mg is a widely used light-weight material, owing to its excellent properties, e.g. specific strength. AM of lattice structures has showcased them as very attractive routes for promoting design-for-performance over design-for-manufacture, specifically when light-weighting is sought. Lattice structures have exhibited outstanding potential for fabricating components with tunable characteristics. Due to their high surface-to-volume ratio, triply periodic minimal surface lattice structures (TPMS) are promising candidates for a wide range of applications. Investigations on the volume fraction and strut thicknesses that are critical to improve the mechanical properties are increasing. This study focusses on the TPMS lattices manufactured in AlSi10Mg using Laser Powder Bed Fusion, investigating the influence of the relative density and strut thicknesses to engineer a desired mechanical performance by combining experimental methods and simulation modelling. Furthermore, the change in behaviour arising when two distinctive lattice structure types are hybridized is evaluated for functional grading. |
