PRINT HEAD FOR ADDITIVE MANUFACTURING OF ARTICLES

The invention relates to additive manufacturing technologies and can be used for manufacturing parts and structures of composite materials reinforced by continuous fibres. 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 fibre, a mechanism for cutting the reinforcing fibre, a feed tube for the plastic filament, feed tubes for the reinforcing fibre and a heating unit. Furthermore, the heating unit includes a heater, a thermocouple or thermoresistor, and two inlet channels - a channel for the reinforcing fibre 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 fibre inside the heating unit, while the inlet channel for the reinforcing fibre is arranged coaxially with the outlet channel for the reinforced plastic.
