This study investigates the application of robocasting technology for fabricating high-density yttria-stabilized zirconia (8YSZ) electrolytes used in solid oxide fuel cells (SOFCs). The primary goal is to overcome the limitations of traditional manufacturing techniques, such as low density and poor microstructural control. Using a combination of hydrothermal synthesis, rheological testing, and robocasting, we achieved dense 8YSZ structures (over 95% density) with minimal porosity. The fabricated electrolytes underwent sintering and debinding processes, with thermal treatment profiles optimized for structural integrity. A microstructural analysis through SEM and XRD confirmed the formation of stable crystalline phase. This research opens new avenues for the…

This study investigates the additive manufacturing of 3D porous scaffolds based on walstromite-type silicate ceramics for bone tissue engineering applications. Walstromite powders were synthesized using the sol-gel method and printed using extrusion-based 3D printing. Both sintered and unsintered scaffolds were characterized using scanning electron microscopy (SEM), Fourier transform infrared spectroscopy (FTIR), X-Ray diffraction (XRD) and energy dispersive X-ray spectroscopy (EDS) analyses to evaluate the effects of sintering on microstructure, porosity, and mechanical properties. Results indicate that the unsintered scaffolds exhibited significantly higher compressive strength due to the presence of organic binders, whereas the sintered scaffolds demonstrated enhanced porosity, facilitating cell…
