Additive Manufacturing, or 3D Printing, is based on manufacturing physical objects by sequential deposition of layers material. Although the usage AM growing, no straightforward methodology exists to produce parts with specific, optimized, mechanical properties. In this work, an approach for optimizing properties specimens under bending stress presented, using DOE. For experimental procedure, Fused Deposition Modeling (FDM) technology was used along Polylactic acid (PLA) as in-process Nozzle temperature, printing speed, infill pattern and orientation were selected factors be optimized achieve so maximum load deflection acquired. Both sets values increased 53% 28%, respectively, experimentally checked validate accuracy approach.

Lattice structures have attracted significant scholarly attention due to their exceptional mechanical properties, including lightweight characteristics and high strength. Their multifunctionality, such as energy absorption vibration reduction, adds versatility. While extensive research has been conducted on the reduction performance of plate‐type, shell‐type, truss‐type lattice structures, studies cylindrical are comparatively limited. To achieve broadband suppression in this study proposes a novel structure based pyramid cells. The bandgap formation mechanism skeleton examined, with quantitative analysis influence structural parameters using normalized indicators. Results indicate that demonstrates multiple bandgaps within 0–1500 Hz range, exhibiting substantial attenuation capabilities. Additionally, adjusting enables shift toward lower frequencies. Finally, experimental verification finite element model performed by comparing transmission curves maximum relative error −7.48% at resonance peak. This work offers valuable insights for application noise control fields.

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.

A novel 316L stainless steel Vertex Modified BCC (VM-BCC) lattice unit cell with attractive performance characteristics is developed. Lattice structure, as well the sandwich panel, are constructed. Numerical simulation utilized to simulate quasi-static compression, dynamic compression and blast behavior considering rate-dependent properties, elastoplastic response nonlinear contact. Finite element results validated by comparing experimental results. Parametric studies conducted gain insight into effects of loading velocity, equivalent TNT load explosion distance on pattern panel. Testing indicate that proposed VM-BCC structure exhibits more superior plateau stress specific energy absorption (SEA) than those or Octet one. The will provide reference for improving protective efficiency in key equipment fields enhancing overall safety.
