Beschreibung
Zusammenfassung:	The invention relates to additive manufacturing technologies and can be used for manufacturing parts and structures of composite materials reinforced by continuous fibers. The technical result is improving physical and mechanical characteristics and reducing the weight of products having a complex shape made of composite materials. The technical result is achieved by a print head containing a mechanism for supplying a plastic filament, a mechanism for supplying a reinforcing fiber, a mechanism for cutting the reinforcing fiber, a feed tube for the plastic filament, feed tubes for the reinforcing fiber and a heating unit. Furthermore, the heating unit contains a heater, a thermocouple or thermoresistor, and two inlet channels - a channel for the reinforcing fiber and a channel for the plastic filament - and a nozzle having an outlet channel for the reinforced plastic. Furthermore, the channel for the plastic filament is connected to the channel for the reinforcing fiber inside the heating unit, while the inlet channel for the reinforcing fibre is arranged coaxially with the outlet channel for the reinforced plastic. The invention makes it possible to increase the physical and mechanical characteristics of the product, to reduce the weight of the product, to reduce the cost of manufacture of complex shape products from composite materials.
