... 13 Lattice structures can be divided into two main categories according to their structural configuration characteristics: (i) 2D lattice structures including honeycomb structures, [14][15][16][17] auxetic structures, [18][19][20] and hierarchical 2D lattice structures 21,22 ; and (ii) 3D lattice structures including truss-based, [23][24][25][26] plate-based, 27,28 shell-based, [29][30][31] and hierarchical 3D structures. 32,33 Truss-based 3D lattice structures include solid and hollow truss, and their cell shapes mainly comprise simple cubic, 34,35 body-centered cubic, 24,[36][37][38] face-centered cubic, 34,39 edge centered cubic, 40 octagonal truss, 23,41 octahedron, 42 double pyramid dodecahedron, 43 rhombic dodecahedron, 44 tetrakaidecahedron, 25 diamond, 36 Kagome, 45 circle, 46 and re-entrant cube. 47 Lattice structures can be categorized based on whether they exhibit bending or stretch-dominated mechanical behavior. ...

... The most common design method of improving mechanical performance of LS is to combine different sub-structures [12][13][14]. Tancogne-Dejean et al. [15] combined body-centered cubic (BCC), simple cubic (SC), and face-centered cubic (FCC) in different ratios to form isotropic plate-lattices that feature the high stiffness, superior yield strength, and excellent energy-absorption. Furthermore, this isotropic plate-lattices depicted 70 % increase in toughness than the conventional lattices [16]. ...
