FIELD: manufacturing technology.
SUBSTANCE: invention relates to a print head for the additive production of articles. Technical result is achieved by a printhead comprising a thread feeding mechanism, a reinforcing fiber feeding mechanism, a reinforcing fiber cutting mechanism, a supply tube for a plastic thread, feeding tubes for the reinforcing fiber and a heating block. Heating unit includes a heater, thermocouple or thermistor, two input channels – a reinforcing fiber channel and a duct for a plastic thread, and a nozzle with an outlet channel for reinforced plastic. Duct for the plastic thread is connected to the reinforcing fiber channel inside the heating block, and the input channel for the reinforcing fiber is coaxial with the output channel for reinforced plastic and has a diameter exceeding the diameter of the reinforcing fiber by no more than 1.5–2 times.
EFFECT: technical result is an increase in the physical and mechanical characteristics of products, a reduction in the mass of products, a reduction in the costs of manufacturing complex-shaped products from composite materials.
