Mechanical properties of HGF. (a) FEA models of lattice, primitive, and gyroid structures and their stress distributions under the same compressive strain along the -direction (the values of σMax for lattice, primitive, and gyroid structure are 600 MPa, 770 MPa and 600 MPa, respectively). (b) Ultralight and (c) Ultrastiff properties illustrated by the gyroidal HGF. (d) Compressive stress-strain curves of HGF with different densities. (e) Compressive strength and Young’s modulus of HGF with different densities.
