Lattice structures are featured by their extraordinary mechanical performances in specific stiffness, strength, energy absorption, and sound etc. The recent trend of multifunctionality engineering applications has raised new requirements for the integration acoustic properties. In this paper, a multifunctional hybrid plate lattice structure denoted as SBHP is proposed hybridizing traditional body-centered cubic (BCCP) simple (SCP) structures, its absorption properties investigated theoretical modeling, simulation analysis experimental verification. effects hole diameters thicknesses on performance impedance matching system damping state analysis. results show that average coefficient SBHP-1 increased 24% 62%, normalized half-absorption bandwidth enlarged 45% 89% than those BCCP SCP, respectively. Heterogeneous constructed using synergistic mechanism strong weak coupling have more outstanding broadband effect. This work provides an effective approach design lightweight with excellent high absorption.

Background: Dental implantology has evolved significantly since the introduction of additive manufacturing, which allows for reproduction natural bone’s porous architecture to improve bone tissue compatibility and address stress distribution issues important long-term implant success. Conventional solid dental implants frequently cause shielding, compromises osseointegration reduces durability. Aim: The current research proposes examine biomechanical efficacy fully hybrid gyroid triply periodic minimum surface (TPMS) latticed across different cell sizes optimize Methods: This study evaluates six implants, including designs with three sizes—FLI_111 (1 mm × 1 mm), FLI_222 (2 2 FLI_333 (3 3 mm)—and TPMS necks in corresponding sizes—HI_111, HI_222, HI_333. To enhance initial stability, a square-threaded design was added into bottom part both lattice implants. also incorporate anti-rotational connections fixation, they undergo clinical viability comparison contemporary designs, finite element analysis (FEA) utilized through nTopology (nTOP 4.17.3) balance stiffness flexibility. mechanical performance under realistic conditions, dynamic mastication loading simulation conducted 1.5 s cycles. Results: findings reveal that particularly exhibited improved characteristics by reducing micromotions at bone–implant interface, improving osteointegration, attaining better distribution. Conclusions: By addressing shielding boosting performance, this work paves way personalized developing technology, results.

Stainless Steel 316L (SS316L) is widely used in orthopaedics due to its biocompatibility, affordability, ease of fabrication, adequate mechanical strength and corrosion resistance. Despite many benefits, the stiffness SS316L has been a significant cause for concern since it causes stress shielding implant failure. A potential solution orthopaedic implants lattice SS316L, which can be fabricated using laser powder bed fusion (LPBF) process. The development structures LPBF process allows scaffolds adhere, grow differentiate bone cells with specific properties suitable implants. study highlights different employed implants, mainly focusing on gyroid delves into fabrication structures. Compared traditional solid TPMS showed at least 30%–70% improvement weight reduction, reduced by 80%, material saving 10%–20% biocompatibility 50%–200% osseointegration. other porous metallic there was 10%–15% compressive tensile strengths. concerning strength-to-weight ratio 40% economically viable. review also influence various parameters biological attributes structures, emphasizing benefits their impact Orthopaedics sector. Furthermore, leveraging unique lattices, offers promising an affordable compatible alternative titanium orthopaedics.
