In a first aspect, the invention refers to a printhead for the additive manufacturing of a fibre reinforced material, comprising a fibre reinforcement in a polymer matrix, comprising an infiltration unit for mixing and/or infiltrating a fibre roving with a molten polymer; at least one feeder for a polymer and/or a fibre roving to the infiltration unit; a heating element, at least for partially melting the polymer within the infiltration unit; at least one deflecting element within the infiltration unit and an outlet for the resulting fibre reinforced material from the infiltration unit, wherein the molten polymer can be guided within the infiltration unit with a polymer flow direction, from the feeder to the outlet, along a channel between the feeder and the outlet, and the fibre roving can be guided within the channel, by means of deflection, around the deflecting element, area by area, transversely to the polymer flow direction, from the feeder to the outlet. In another aspect, the invention refers to the use of a printhead for additive manufacturing, as well as to a process for additive manufacturing, and to a fibre reinforced material produced by the printhead.
