Abstract Lattice metamaterials emerge as advanced architected materials with superior physical properties and significant potential for lightweight applications. Recent developments in additive manufacturing (AM) techniques facilitate the of lattice intricate microarchitectures promote their applications multi‐physical scenarios. Previous reviews on have largely focused a specific/single field, limited discussion properties, interaction mechanisms, multifunctional Accordingly, this article critically design principles, structure‐mechanism‐property relationships, enabled by AM techniques. First, are categorized into homogeneous lattices, inhomogeneous other forms, whose principles processes discussed, including benefits drawbacks different fabricating types lattices. Subsequently, structure–mechanism–property relationships mechanisms range fields, mechanical, acoustic, electromagnetic/optical, thermal disciplines, summarized to reveal critical principles. Moreover, metamaterials, such sound absorbers, insulators, manipulators, sensors, actuators, soft robots, management, invisible cloaks, biomedical implants, enumerated. These provide effective guidelines

Broadband low-frequency sound absorption is highly sought in engineering applications, but the size of sound-absorbing metamaterials still poses challenges. By revisiting Helmholtz resonator, we propose a multi-layer overlapping structure. This structure adopts simple design nested multiple resonators, creating composite effect coupling three-dimensional buckling acoustic cavity with discontinuous cross-sectional effects, significantly improving effective depth external within finite dimension. To reveal its complex characteristics, high-fidelity correction method was proposed to calculate increase Experimental validation has been conducted evaluate accuracy current model. increases by about 38% total thickness 63 mm, achieving broadband from 320 690 Hz using non-parallel units. work provides new and unique insights for designing metamaterials.
