An 3D printing is a popular additive manufacturing tool that attracts attention from many sectors and direct slurry writing (DSW) printing is a suitable technique for creating functional ceramic material. This study investigates the suitable formula with various additives and binders and the process conditions that influence DSW printing quality. To combine the unique properties of PVP and PEG binders and attapulgite, various ceramic slurry formulas of attapulgite and TiO2 mixture were prepared for direct slurry writing (DSW) printing. Establishing both qualitative and quantitative assessments on the rheological outcomes, the ceramic slurry formula, printing parameter, drying, and sintering conditions, and the binder ratio for ceramic slurries was optimized. The results showed that the most optimal ratio for ceramic slurries is with 10% PVP or 5% PEG binder and the optimal attapulgite:TiO2 ratio is 1:1, which the slurry showed no cracking or deformation when air dried, as well as no collapse and cracking after 900 C sintering. The optimized printing parameters for attapulgite-based ceramic slurry printing layer heights of 0.8 mm, the printing pressure of 0.10 MPa, and the printing speed at 20 mm/S. XRD confirmed that TiO2 is a rutile phase. The stable and less active rutile phase of TiO2 as a photocatalyst is confirmed by the inhibition zone test and growth inhibition assay. SEM results further showed agglomeration of TiO2 after high-temperature sintering. This study lays a foundation for the attapulgite application in DSW printing to take advantage of its large specific surface areas.
