Summary: In this study, the fatigue behavior of the porous biomaterial Ti6Al4V-6Cu, produced by selective laser melting (SLM) in air and in 0.9 wt% NaCl solution, was experimentally investigated. It was found that crack initiation is accelerated in a state of high stress and crack propagation is accelerated in a solution containing 0.9 wt% NaCl. Moreover, the porous Ti6Al4V-6Cu sample has a higher fatigue strength and longer fatigue life compared to the Ti6Al4V sample.

Summary: Selective laser melting (SLM) was utilized to produce CuZrAl metallic glass (MG) scaffolds with combined lattice structures of body-centered cubic and face-centered cubic (F2BCC), and the effects of lattice structures on mechanical behavior were investigated. The results revealed that curved struts remarkably enhanced compressive ductility by 122% and energy absorption by 106%. The presence of curved struts effectively prevented catastrophic shear fracture and delayed fracture occurrence due to the release of strain concentrations. This study demonstrates the potential of improving the ductility and toughness of SLM MG components through appropriate lattice structure design.

Summary: Lattice structure, with characteristics of low density, high specific strength, and high specific stiffness, is suitable for applications in secondary load-bearing components. Research shows that ARCH lattice structure exhibits better flexural properties under Y loading direction, and the relative density has a significant influence on its flexural properties. The Gibson-Ashby equation is established to estimate the flexural properties of lattice structures with different relative densities, providing a theoretical basis and reference for engineering applications.

Summary: This study aims to investigate the influence of laser power on the microstructural evolution of a novel Ti-6Zr-5Fe alloy fabricated by selective laser melting (SLM). The microstructural evolutions of the top surfaces in SLM Ti-6Zr-5Fe alloy samples fabricated from 80 W to 140 W were thoroughly examined. The increase in laser power resulted in larger size of the b phase and a phase due to decreased cooling rate, as well as increased melt pool overlapping, leading to re-heating or re-melting. The findings demonstrate that laser power can effectively regulate and control the microstructure and microhardness of SLM Ti alloys.

Summary: In this study, the microstructure and mechanical properties of Ti-6Al-4 V alloy fabricated by SLM were investigated. It was found that high-speed laser scanning during solidification led to the formation of beta columnar grain and multistage acicular alpha phase. Higher energy density also resulted in increased size of these structures. Different crystallization types were observed in the molten pool due to varying temperature gradients and heat flow directions. Grain size and densification degree, influenced by energy density, had a significant impact on mechanical properties. The anisotropy of tensile characteristics was determined by the geometry of the molten pool boundary and growth direction of the microstructure. The optimal energy density of 74.07 J/mm3 resulted in the highest tensile strength and strain.

Summary: In this study, Ti6Al4V (Ti64) cubic porous lattice structure (PLS) scaffolds fabricated using selective laser melting (SLM) technique were analyzed, revealing a maximum ultimate compressive strength of 119 MPa for PLS with a pore size of 600 μm and an overall relative density of 57%. The failure of the structure was observed to begin from micro-porosity formed during the fabrication process due to improper melting along a plane inclined at 45 degrees.

Summary: This study investigates the effect of modulation assisted drilling (MAD) on the quality of holes drilled in nickel-based superalloy Inconel-718. It was found that low-frequency vibrations can reduce positional error, thrust force, and torque, leading to a higher machining quality by decreasing frictional heat, tool wear, and thrust force.

Summary: Titanium and its alloys are commonly used materials for orthopaedic and dental implants, with implant failure often attributed to issues such as poor osseointegration, bone resorption, and post-surgical infections. Localized drug delivery through surface modification techniques, either using a drug-loaded carrier or directly loading drugs onto the implant material, is a promising approach for addressing these challenges. Research in this area focuses on controlled drug release and the mechanical and physical stability of the coated or adsorbed materials.

Summary: This paper presents an analysis and theoretical model for evaluating the quality and accuracy of wire-cut electro-discharge machining (WEDM) of heat-resistant nickel alloys. The study found that WEDM processing of Ni alloy resulted in high surface roughness for thick specimens, and electrical parameters had little influence on the surface roughness. The cut width of the machined surface decreased with increasing pulse duration, except for thick workpieces. Secondary discharges in WEDM had negative effects on processing quality and productivity. A regression model was developed to predict surface roughness and cut width, which is significant in modern engineering.

Summary: Plantar foot pain is a common condition in occupations that require prolonged standing, such as nursing. The etiology of plantar foot pain is unclear but likely multifactorial, with increased standing hours being a risk factor. Current treatment methods, such as orthoses and insoles, have limited customization and scientific advancements. This study developed a novel 3D-printed customized foot orthosis and found that it effectively reduced pain and pressure, and improved functional ability in nurses compared to traditional methods.
