Conclusion Thus, there was studied the influence of wire feed rate, beam current, sample move speed on the stability of the process of layer-by-layer deposition and formation of AISI 304 wire products by electron-beam additive manufacturing. It has been established that it is possible to form a product without melting of previously formed layers and without defects with  B = 583 М P а at a combination of technological parameters ( I e = 40 mA; V w = 180 mm/min; k = 1.3), for which the value of the linear energy approaches 400 kJ/m (mode 5). It is shown that using the highest values of the deposition rate and the layer fill factor ( V w = 320 mm/min; k = 1.3) while varying the electron-beam current do not allow the product to be printed. The studies show that obtaining samples by varying the technological parameters of the additive electron-beam method, which allows forming products with a satisfactory shape and size without disturbing macrogeometry in the printing process (modes 1, 2, 4-6), leads to obtaining samples with mechanical properties that differ in narrow limits (558-595 MPa).
