The subject of this study focuses on the effect of 3D printing and heat treatment of thin-walled models made of ceramic paste. The plates with dimensions of 20*5*40 mm were used as the models. The methodology includes the creation of ceramic objects using 3D printing by the SLA method (stereolithography) and their further heat treatment. The surface quality and the shrinkage percentage of samples printed in different modes and thermally processed under different conditions are compared. It was found that with a decrease in layer thickness and particle size, as well as an increase in the duration of heat treatment, the surface quality of the samples improves and the percentage of shrinkage decreases approximately 2 times. Using new modes and improved heat treatment conditions, samples with the least number of cracks and a lower percentage of shrinkage were obtained, which allows using this process to create ceramic products of higher quality. The method of creating ceramic products used in the work in the future can be applied in such industries as aircraft manufacturing, medicine, biotechnology and other fields.
