3D Bioplotter Research Papers

Energy has been one of the hottest topic in the last two decades and therefore the energy storage devices have attracted significant attention. Na ion battery is considered as an alternative to Li ion battery for next generation energy storage devices. β/β’’ alumina solid electrolyte (BASE) for solid-state Na ion battery has been widely investigated since last century, however the fabrication of BASE with complex 3D-structure is still unfulfilled. In this project water-based BASE ink formulations were developed for material extrusion additive manufacturing technique. The fabrication of BASE with complex 3D-structure was achieved which massively extended the potential of BASE…

Bio-inspired multi-scaled (hierarchical) porous structures have remarkable strength and stiffness-to-density properties. Direct ink writing (DIW) or robocasting, an additive manufacturing (or also commonly known as 3D printing) material extrusion technique is able to create near-net-shaped complex geometries. A new approach of combining DIW, colloidal particle-stabilized emulsion paste inks and partial densification to create tailored architectures of hierarchical porosity on three scales has been demonstrated. The printed and sintered ceramic lattice structures possess relatively high overall porosity of 78.7% (on average), comprising mainly (64.7%) open porosity. The effects of formulation (surfactant and oil concentrations, solids particle size, and mixing speed) on…
