Metal hollow-strut lattices manipulate the strut and node sections to achieve higher strength. Although these metamaterials have recently surpassed structural efficiency of conventional solid-strut comparable density topology, they often observe localised yielding fragmentation through nodes that limit their efficiency. To quantify effect this failure develop mitigating strategies, we integrated solid hollow in singular Ti–6Al–4V simple cubic hybrid-strut for a deployable relative range 15–30%. Fabricated laser powder bed fusion are stronger (32%), stiffer (15%), tougher (65%) than equivalent density. Interestingly, with beams can transition from bending-dominated stretch-dominated deformation response increasing density, while only observed uniformly response. The combination lattice establishes yet effective strategy enhance control without or manipulating unit cell topology.

Abstract Metal thin‐walled structures are ubiquitous in various industrial applications and fabricating them through additive manufacturing (AM) enables intricate thin‐wall geometries with no assembly required. However, additively manufactured metal thin walls suffer from increased heat accumulation reduced structural stability, making it difficult to print geometrically accurate minimal distortion defects. Thin‐walled also experience different thermal histories solidification conditions compared bulk structures, leading drastic differences the microstructure mechanical properties. In this review article, AM processing of will be introduced. An in‐depth discussion on design strategies presented regarding restrictions imposed by technology, integration lightweight novel ideation topology optimization. The effects that wall has geometrical accuracy, microstructure, properties then elucidated. utilization for across industries summarized. Finally, article close some perspectives future work structures.

Lattice materials demonstrate exceptional advantages in lightweight design applications due to their low mass density, high specific strength, and customizable topology. Inspired by the hollow vascular bundle structure of bamboo, this study develops four bio-inspired lattice configurations through two key modifications conventional body-centered cubic (BCC) structures: Z-axis (loading direction) strut reinforcement hollowing. The specimens were fabricated using AlSi10Mg powder via selective laser melting (SLM) technology, followed systematic evaluation compressive properties energy absorption characteristics. experimental results reveal that synergistic combination Z-strut significantly enhances both resistance capacity. optimized BCC-5ZH configuration (5 Z-struts with full hollowing) achieves remarkable performance metrics at 0.5 g/cm3 density: yield strength (16.78 MPa), (27.91 volumetric (10.4 MJ/m3). These values represent 236.9%, 283.4%, 239.3% enhancements, respectively, compared reference BCC lattices an equivalent density. integration induces homogeneous stiffness distribution throughout architecture, while hollowing increases effective moment inertia. This structural evolution a failure mode transition from single shear band deformation dual X-shaped propagation, resulting enhanced sequence regulation within system.
