Precision investment casting is one of the longest known superalloys forming techniques. Nowadays, it is primarily used to manufacture precision castings with high surface quality. It is widely utilized in the aircraft industry for jet engines turbine blades production. Fabrication of multilayer ceramic casting mold is a complicated and time consuming process, which is also burdened with high risk of failure due to the their cracking during wax pattern melting process [1,2]. This work presents studies concerning applicability of a thermo-visual camera in ceramic shells molds cooling process. Moreover, ceramic materials and slurries have been investigated. There were slurries prepared for near-model (first layer) and construction layers of a shell mold. Using the pre-prepared slurries, the ceramic near-model (first layer) and construction layers were made on a wax pattern. Cooling was tested with the thermo-visual camera in the 300Ai-40Ai°C temperature range.
