The article describes the development of mathematical models and user environment in the APD language which are based on the finite element system solver and allow for the SLM physical process numeric modelling with the required accuracy. The main task is to evaluate the final shrinkage and residual strength of the blanks of gas turbine parts for optimizing the technological process of production. The activities on introducing pre-distortions into the part geometry were performed to compensate for thermal deformation during the growth process; the part with pre-distortion was produced and controlled.
