Preparation of silicon carbide ceramic slurry for stereolithography based additive manufacturing

Stereolithography-based additive manufacturing of ceramics has received tremendous attention in academic and industrial communities. In order to fabricate silicon carbide (SiC) components with complex shapes by stereolithography, a high SiC loaded ceramic slurry low viscosity excellent curing ability is required. However, it challenging meet these requirements. this work, the effects resin formulation, dispersant, particle size, solid content ball milling time on properties were systematically studied. The slurries prepared using four precursor powders having different sizes modified temperature oxidation reduce its UV absorbance. Additionally, suitable for stereolithography under appropriate processing parameters, geometrically green bodies subsequently fabricated.
