Manufacturing complex-shaped metal products by 3D-printing is becoming ever more urgent in modern industry. Laser technologies (SLS- and SLM-processes) are most often applied for this purpose, while electron beam technologies (EBF3) are used less often. Both of them are characterized by quite high cost and low efficiency. This paper deals with new tendencies in application of welding technology for 3D-printing of complex metallic products, including those complemented by concurrent or subsequent machining. It is shown that application of welding technologies to produce volumetric metallic products significantly lowers their manufacturing cost at simultaneous increase in productivity, compared to SLS- and SLM-processes. The most promising welding technology of 3D-printing is plasma-arc process with application of wires or powders. It allows at comparatively low heat input creating quality volumetric products with 3-50 mm thickness from Fe, Ni, Co, Cu, Ti, Al alloys, as well as composite materials containing refractory components. Application of welding technologies allows producing both comparatively small and long products, not requiring any finish machining (for instance, growing stiffeners on large-sized panels, manufacturing honeycomb panels, building structures, etc.). Combination of welding technologies of 3D-printing with concurrent or finish machining (mostly, by CNC milling) allows manufacturing ready for use metal products of complex profile.
