Abstract
The aim of the work is to analyze and optimize the shaping of GTE blade in the process of fabrication using additive electron beam technology. Using the method of computer simulation in the Simufact Additive software, the influence of technological printing parameters on product shaping was investigated, and shrinkage phenomena that occur during the printing process were analyzed. The printing simulation was performed and the results were compared to the reference model. The optimized computer models of GTE blades were created. According to the calculation results, when optimized models are used, the deviation in the geometric dimensions of printed blades does not exceed the product size tolerances of ±0.3 mm.
