Investigations on Additive Manufactured Gyroid Lattice Structures Using AlSi10Mg

Abstract

Abstract Lattice structures are three-dimensional frameworks characterized by an interconnected network of struts or beams, often resembling geometric shapes such as gyroids. This study investigates the compressive behavior of functionally graded gyroid lattice structures fabricated from AlSi10Mg using selective laser sintering. Through systematic variation of design parameters such as relative density, cell size, uniform wall thickness, and gradient of wall thickness, the research examines how these factors affect mechanical stability and collapse mechanisms under load. Compression testing provides insights into strength, deformation, and failure modes of the structures, offering valuable contributions to the understanding of their compressive strength. The findings have significant implications for applications requiring lightweight yet robust structures, particularly in aerospace, automotive, and other engineering disciplines, thereby advancing the field of metal additive manufacturing and its potential in advanced structural designs.
