  • PRINT HEAD DESIGN FOR ADDITIVE MANUFACTURING USING CONTINUOUS FIBERS AND THERMOPLASTIC MATRIX MATERIALS FOR CUTTING IN THE HOT ZONE OF THE PRINT HEAD BY AN AXIAL OR ROTATIONAL MOVEMENT
    Publication number: 20240351279
    Abstract: A print head for additively manufacturing fiber-reinforced composite materials includes a feed channel, a heating block, a nozzle and a cutting unit. A filament of the fiber-reinforced material enters an inlet of the nozzle through the feed channel, leaves the nozzle via an outlet of the nozzle, and is deposited on a print bed. The cutting unit is located inside the heating block which has a beneficial effect on the cut and/or the shearing of the material to be printed. The invention also relates to a method in which the filament is cut and/or sheared, wherein the cutting unit performs a linear movement or rotation, or the print head per se performs a linear movement or rotation, as a result of which the filament is cut and/or sheared off.
