Effective magnetic susceptibility of 3D-printed porous metal scaffolds

Greg Hong et al.

Summary: This study found a linear correlation between the effective susceptibility of porous metal scaffolds and the porosity. Highly porous implants have low effective susceptibilities, making them more suitable for routine MRI imaging.

Modal characterization of additively manufactured TPMS structures: comparison between different modeling methods

Ugur Simsek et al.

Summary: This paper investigates the modal characteristics of additively manufactured TPMS structures using five different modeling methods, comparing their computational efficiency and accuracy. Experimental validation and parametric studies are conducted, leading to a relationship between modal characteristics and volume fraction.

The potential use of a gyroid structure to represent monolithic matrices for bioseparation purposes: Fluid dynamics and mass transfer analysis via CFD

Jamille C. Coimbra et al.

Summary: This study applies the gyroid model to represent the structure of a cryogel and investigates mass transfer and adsorption through Computational Fluid Dynamics simulations. It is found that at high flow rates, there are hydrodynamic abnormalities that negatively impact the adsorption process.

The influence of selective laser melting defects on the fatigue properties of Ti6Al4V porosity graded gyroids for bone implants

Dalia Mahmoud et al.

Summary: The study tested the manufacturability of gyroids and found that geometric errors and internal defects during the manufacturing process can affect the mechanical properties of metallic lattice structures. Designs with graded porosity showed higher elastic modulus and compressive strength, but lower fatigue strength.
