The solvent-based ceramic slurry stereolithography (3S) technique offers a novel approach to fabricating complex structures, yet its potential in the realm of alumina specimens and ultra-thin veneers remains underexplored. The present study assessed the impact of the debinding process on the microstructure and mechanical properties of 3S-fabricated alumina specimens, while also evaluating the fit of ultra-thin veneers with a thickness of just 0.3 mm. The results indicated that variations in debinding parameters—such as different rates and holding times—do not significantly affect surface morphology, density, Vickers hardness, or flexural strength. Additionally, the cell viability of 3S-fabricated specimens exceeded 90% for both MG-63 and NIH-3T3 cells, suggesting excellent biocompatibility. The mean marginal and internal gaps of the 3S-fabricated veneers were within clinically acceptable ranges, measuring 93.38 ± 29.53 μm and 130 ± 46.1 μm, respectively. These groundbreaking insights not only validate the robustness of the 3S fabrication technique but also highlight its promising potential for biomedical applications, distinguishing this research in the field.
