Abstract
This research presents a novel UV-assisted drop casting approach for shaping ceramic microbeads from aqueous-based UV-curable alumina suspensions. The work focused on optimising suspension composition and shaping conditions to obtain dense microbeads with high sphericity. The effects of dispersant concentration, solid loading, monomer ratio, and photoinitiator content on rheology and UV curing were systematically investigated. The optimal suspension (42.5 vol% alumina; water:2-hydroxyethyl acrylate:poly(propylene glycol) dimethacrylate ratio 10:9:1; 5 wt% dispersant; 0.5 wt% photoinitiator) showed shear-thinning behaviour and a cure depth of 580 µm. Shaped droplets were UV-cured in a hydrophobic medium, and thermal analysis enabled controlled debinding and sintering. The best series yielded beads with an average diameter of 1262 µm, circularity up to 0.99, and low dimensional variability. Dense microstructures with minimal porosity were achieved, though surface delamination and grain coarsening occurred. The method enables efficient fabrication of spherical ceramic elements with high structural integrity.
