The article is devoted to the technology of high-speed direct laser deposition of Ti-6Al − 4V titanium alloy samples. The paper aims at the development of the production technology of titanium blisc for machining. Natural experiments were conducted to select optimal process regimes ensuring the absence of defects in the form of pores, fusions, cracks; samples of various configurations for mechanical testing were also produced. As a result, the optimal parameters of high-speed direct laser deposition regime, ensuring the formation of a defect-free structure and optimal mechanical properties of the samples, were established. The oxygen level, at which it is possible to obtain products with mechanical properties matching those of Ti-6Al − 4V alloy, obtained with traditional methods, content in the chamber, is also established. A blisc model from a powder titanium alloy Ti-6Al − 4V was made using optimal regimes under the method of high-speed direct laser deposition.
