Abstract
The use of metal-powered composition made of steel with chromium and nickel additives 12X18H10T for use in additive 3D printing technologies by selective laser fusion method (SLM) is considered. The effect of laser radia-tion power and the scanning rate of the laser beam on the solidness of the resulting steel in samples was investigated. Features of the for-mation of material in the process of selective laser melting of metal, the technological features of the equipment are determined. Results on the physicomechanical properties of the alloy ob-tained by SLM are obtained: the strength of the samples after quenching at a temperature of 1050 ° C - 660 MPa; The yield strength is 356 MPa, the relative elongation is 40 %.
