Novel strut-based stochastic lattice biomimetically designed based on the structural and mechanical characteristics of cancellous bone
This study introduces a strut-based stochastic lattice structure with excellent three-dimensional (3D) isotropy and structural design flexibility, inspired by the cancellous bone network.

| description | This study introduces a strut-based stochastic lattice structure with excellent three-dimensional (3D) isotropy and structural design flexibility, inspired by the cancellous bone network. Termed the cancellous bone-inspired stochastic network (CBSN) lattice, this framework mimics the structural and mechanical features of cancellous bone. The CBSN lattice consists of a 3D network of interconnected beams, where beams are initially isotropically bifurcated and beam length and the number of connections at each node are stochastically determined, with some beams linking to the nearest nodes. Structures were successfully constructed with volume fractions ranging from 21.9% to 74.1% and internal structures with strut diameters up to 1.4 times, mean beam lengths up to 1.9 times, and bifurcation patterns dominated by triple and quadruple bifurcations. Structural indices exhibited minimal stochastic variation across iterations and beam orientations remained largely unbiased, including the isotropic nature of triple and quadruple bifurcations. Four primary design variables were identified to control the volume fraction, mean beam length, and bifurcation properties. Additionally, a representative CBSN lattice was successfully additively manufactured via laser powder bed fusion using maraging steel. The findings demonstrated the stable stochastic construction, high 3D isotropy, and extensive structural design flexibility of the CBSN lattice structure. |
