Abstract
The construction of rapid prototyping for structured ceramics has a promoting effect on potential applications. In this work, engineering slurry with different formulations were used to develop aqueous colloidal ceramic slurry for direct ink writing (DIW). Optimized slurry of Formulation 5 possessed good printing effect for DIW with stable mechanical properties. Related characteristics, including shrinkage, compressive strength, rheological behavior, and chemical property, were also examined. DIW ceramics prepared from optimized slurry can be preliminarily applied to adsorption of Rhodamine B and chlortetracycline, and possessed the advantages of easy separation and operation compared with powder adsorbents. This work provides a strategy for the design of 3D-printed kaolin ceramic slurry, and also extends to potential application in adsorption. The construction of rapid prototyping for structured ceramics has a promoting effect to potential applications. Engineering ceramic slurry with different formulations were explored to develop aqueous colloidal ceramic slurry for direct ink writing (DIW) in this work. • Slurry with different formulations were explored to develop aqueous colloidal ceramic slurry for direct ink writing. • Optimized slurry of formulation possessed good printing effect for DIW. • DIW ceramics had good adsorption effect for chlortetracycline and Rhodamine B with advantages in separation and recycle.
