Methylcellulose-based alumina-titania composite (97:3 wt.%) inks were prepared by mixing 1 wt.% and 3 wt.% methylcellulose solution with 35 wt.%, 50 wt.%, and 65 wt.% of solid loading to obtain alumina-titania composite inks. The prepared inks were characterized for rheological behavior. Significant effect of solid loading of alumina-titania composite powder was observed on the viscosity of the alumina-titania composite inks. The viscosity of the composite inks increased with increased solid loading. Also, it was observed that the gelation temperature decreased with increasing solid loading of alumina-titania composite powder in the composite inks. The viscosity vs shear rate for the composite inks showed shear thinning behavior which is suitable for direct ink writing. The yield stress of the composite inks was found to increase significantly with increasing solid content at 35 °C.
