Abstract: The invention relates to the field of additive technologies and can be used for manufacturing components and structures made of composite materials. A device comprises an extruder having inlet channels, a heater, a camera, a temperature sensor, a nozzle for material discharge, mechanisms for feeding material and composite fiber in the form of thread, a thread-cutting mechanism, a table and a three-dimensional displacement mechanism. A method comprises manufacturing composite fiber, feeding the fiber and thermoplastic material into the extruder, and heating up the extruder, wherein the thermoplastic material is combined with the composite fiber. The composite material is then extruded onto the surface of the table, where the composite fiber cools and hardens, and the melt of thermoplastic material solidifies, bonding the composite fibers to one another and forming the article.

Abstract: 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.
