This article discusses the results of the development of a promising technology for manufacturing parts of gas turbine engines. First of all, this technology is promising due to the use of the PolygonSoft system utilized for computer modeling of casting processes, which made it possible to evaluate the efficiency of the gating and feeding system, as well as to predict the appearance of casting defects (porosity and macrostructure discrepancies) and to develop a set of measures for their detection and elimination; second of all, due to the use of rapid prototyping which employs 3D printing of the master model, thus reducing the time and financial costs for the preparation of technological equipment. According to preliminary estimates, the use of rapid prototyping has reduced the cost of manufacturing 250 wax models by 15% in comparison with the traditional technology, and also reduced time costs by an average of 5-6 months.
