Manufacturing process of water-soluble salt-based ceramic cores based on vat photopolymerization
Source abstract
Abstract
The water-soluble salt-based ceramic cores can be recycled and have excellent high-temperature chemical stability. In this work, vat photopolymerization had been successfully applied to water-soluble salt-based ceramic cores for the first time. The powder raw materials of the printing suspension were sodium chloride and alumina. High-precision green bodies were manufactured by optimizing suspensions and parameters. In addition, the post-processing method had been optimized according to the microstructure and mechanical properties. The sintered part had high bending strength and smooth surface. Finally, the dissolution rate and moisture resistance were compared under different dissolution and storage conditions. Compared to traditional manufacturing methods, vat photopolymerization enables the production of complex structures without molds and reduces production costs. This technology is suitable for the rapid iteration of complex structural parts and can be applied to precision parts in aerospace, military, and other technical fields with high cost-effectiveness and sustainability.
