To address the anisotropy of mechanical properties and challenge removing support materials in lattice structures fabricated using fused deposition modeling (FDM), this study is inspired by traditional woodworking mortise tenon joints. A hexagonal interlocking structure was designed, (MTLSs) with various parameters were fabricated. Compared integrated forming (IFLS), MTLS exhibits maximum reductions side surface roughness (Ra), printing time, material consumption 74.87%, 25.55%, 52.21%, respectively. In addition to enhancing quality efficiency, also exhibited superior properties. The uniaxial compression test results show that specific strength, energy absorption (EA), (SEA) exhibit increases 51.22%, 894.59%, 888.39%, respectively, compared IFLS. Moreover, effects strut angle thickness on analyzed. Smaller angles larger thicknesses endowed greater while smaller contributed higher absorption. This proposes a novel approach for designing additive manufacturing.
