Study on Additive Manufacturing and Properties of Photocurable Ceramic Body
摘要
Abstract
In order to meet the usage requirements of photo curing additive manufacturing of ceramic slurry,the morphology of ceramic powder was observed,and the effects of dispersant type and solid content on the apparent viscosity of ceramic slurry were investigated.The optimized ceramic slurry was then photo cured.The results showed that the ceramic powder was evenly dispersed,with a particle size mainly distributed between 200~500 nm and a D50 of approximately 0.32 μm.KOS110 as a dispersant can effectively reduce the apparent viscosity of ceramic slurries;At a shear rate of 50 s-1,as the amount of dispersant added increased from 1%to 8%,the apparent viscosity of the ceramic slurry first decreased and then increased.The minimum apparent viscosity of the ceramic slurry was obtained when the amount of dispersant added was 2%.At the same shear rate,the larger the volume fraction of solid content,the higher the apparent viscosity of ceramic slurry.The appropriate solid content of ceramic slurry should be 52%or less.When the scanning speed was between 1 m/s and 10 m/s,the curing depth of the ceramic slurry was higher than the design thickness(25 μm),meeting the requirements for additive manufacturing of ceramic slurry.关键词
