Static and dynamic crushing of polymeric lattices fabricated by fused deposition modelling and selective laser sintering-an experimental investigation

Z. P. Sun et al.

Summary: The study found that lightweight polymeric lattices fabricated by SLS exhibit good energy absorption performance under quasi-static compression, but are prone to catastrophic collapse when subjected to impact. The use of different manufacturing techniques, such as FDM, can result in lattices with better energy absorption characteristics. The novel HS lattice design shows superior energy absorption characteristics for all tests compared to traditional octet and RD structures.

Two elastically equivalent compound truss lattice materials with controllable anisotropic mechanical properties

Shuheng Wang et al.

Summary: Compound lattice structures, such as BCS-I and BCS-II, with high stiffness and strength can have their anisotropic elastic properties and strength controlled by adjusting relative thicknesses and densities. BCS-I shows better buckling resistance compared to BCS-II, while both materials exhibit the same elastic properties and initial yield strength. This study suggests that rational design and selection can lead to improved performance of a wide range of truss systems without the need for additional materials.

Compressive performance and energy absorption of additively manufactured metallic hybrid lattice structures

Lijun Xiao et al.

Summary: A hybrid lattice cell configuration combining an octet cell and a rhombic dodecahedron (RD) cell was proposed to achieve superior mechanical performance and energy absorption capacity. Experimental and numerical results demonstrated that the hybrid structure outperforms the individual octet and RD lattice structures in terms of energy absorption, and its performance can be further enhanced by tuning the mesoscopic architectures.

Compression behavior of strut-reinforced hierarchical lattice-Experiment and simulation

Zhonggang Wang et al.

Summary: The reinforcement design of lightweight lattice structures using the strut-reinforced concept based on space filling has shown superior mechanical performance compared to conventional lattice structures. The specific characteristics generated by the hierarchical configuration contribute to enhanced compression behavior. The influence of geometry variations, particularly the function of struts, becomes more dominant as the diameter increases.

A topology strategy to reduce stress shielding of additively manufactured porous metallic biomaterials

Lei Zhang et al.

Summary: A topology strategy of designing double-cone struts was proposed to reduce stress shielding of diamond-like porous metallic biomaterials while maintaining unvaried porosity. Experimental results showed that the elastic modulus and yield strength of DCD structures were significantly lower than those of UD lattices, which could match the mechanical properties with the host bone and avoid stress shielding. The study demonstrated that the double-cone topology strategy has great potential in the field of orthopedic implants.
