Effects of Net and Solid Skins on Self-Supporting Lattice Structures

摘要: Multi-functional capabilities of Lattice materials allow them to be used in weight bearing applications, impact absorption and heat dissipation. Previously, the range cellular was limited by constraints traditional manufacturing technologies. This situation has been mitigated advances additive (AM) techniques, which allows manufacture complex parts directly from three dimensional CAD models. However, other difficulties emerge with AM techniques. Such exist metallic components produced selective laser melting (SLM). The need for support could compromise quality lattice being built since it is difficult remove such structures. Lattices requiring little or no are better suited SLM. A method recently developed fit lattices complicated domains consist an approach improve performance trimmed solid net skins. In this paper, we investigate influence these skins on stiffness Body-Centred Cubic (BCC) Double-Gyroid (Dgyroid) via finite element analysis. Including a skin BCC improved its as thickness increased. Dgyroid insensitive skin. both types.
