Additive manufacturing has given a way to manufacture complex-shaped ceramic parts, which is impossible with conventional manufacturing methods. This paper demonstrated stereolithography printing and sintering of Silicon Carbide (SiC) ceramics via oxidation-bonding. The commercially available SiC powder and the photopolymer resins were utilized for stereolithography printing. Experiments were designed to study the effect of printing process parameters with the increase in SiC powder loading for the photopolymer slurry. It was observed that the curing time increased drastically with SiC powder loading. The SiC green parts were sintered at 1200°C in the air. The SEM-EDS analysis of sintered parts showed evidence of bonding the SiC particles via oxidation. This study paves the way for additive manufacturing of high-density and high-strength SiC/Silica composites.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
