N2 - In order to avoid the shell cracking during baking process of quick investment casting based on stereolithography (SL) pattern, an expanding model of SL pattern-ceramic shell is proposed via analyzing the interaction between investment shell and SL pattern, then the cracking condition of investment shell is given. This model has been applied in quick casting of the new engine turbine nozzle vane. The experimental results show that if such technology parameters as the baking speed, wall thickness, and SL pattern thickness are suitable, or the size of SL pattern in one direction gets very small, shell can be prevented from cracking during baking process.
