Fig. 9: Counter validation: design and manufacturability of a strut inclination-insensitive (SII) complex octet-truss lattice.

a Cubic unit cells are embedded within each hexahedral element and interconnected to form the lattice. The mesh model is identical to that shown in Fig. 5b; however, all struts maintain a uniform diameter of 200 μm, irrespective of their inclination. b The PBF-LB/M-fabricated SII lattice exhibits poor strut connectivity, with localized disconnections (red arrows) and excessively large strut diameters in certain areas (yellow arrows).
