Additive manufacturing (AM) using laser powder bed fusion (LPBF) enables the fabrication of intricate biomimetic structures, such as triply periodic minimal surfaces (TPMS), which hold significant potential for biomedical implants. However, fatigue performance these structures is often compromised by surface roughness and internal defects. In this work, Triply (TPMS) based lattices were fabricated LPBF process. Quasi‐static compression tests computational fluid dynamics (CFD) simulations...

The ability of bone to regenerate itself through mechanobiological responses is its dynamic property. Mechanical cues from a neighboring environment produce the structural strain promote blood flow and marrow mobility that in turn aids regeneration process. Occurrences these phenomena are crucial for success metallic scaffolds implanted host tissue. Thus, permeability fluid flow-induced wall shear stress (WSS) two parameters directly influence cell bioactivities inside scaffold effective...

Diverse, often inter-disciplinary, approaches have been proposed to advance the conservation of lions ( Panthera leo ) and their natural habitats. The IUCN guidelines for in Africa call effective national policies at all scales, legal frameworks with specific Action Plans preferably a regional/population level, achieve goals lion while also planning equitable distribution costs benefits amongst local communities. However, general must be tailored circumstances, so here we provide an overview...

The use of Ti6Al4V for orthopedic implants though widely accepted, is 10X stiffer than bone, that leads to stress shielding and aseptic loosening. Further, oral delivery demands significantly large dosage drugs. To address these twin challenges, we have fabricated open cell porous scaffolds capable sustained dual drug delivery. Drug from a promising approach in situ dental implant applications. In this study, selective laser melting technology was used fabricate ELI 50 % volume fractions...

This paper describes the effect of various flushing conditions on accuracy deep holes drilled via micro electrical discharge machining (EDM) machining. Copper tubes were used for hole drilling in copper. Various dielectric (side jet flushing, through combined with side immersion flushing) evaluated their diameter variation, overcut and circularity at workpiece entrance exit drilled. Through observed suitable whereas its combination unsuitable higher aspect ratios holes.
