The application belongs to the technical field of additive manufacturing material preparation, and particularly relates to a preparation device and method of high-fiber-content reinforced polyether ether ketone 3D printing wire rod, which comprises: a material source assembly for providing an impregnated tape; a filament splitter in communication with the material source assembly, which divides the wide impregnated tape into multiple narrow strips through a cutter shaft and a circular disc split cutting knife; multiple multi-nozzle step-by-step pultrusion devices corresponding to the narrow strips, which are provided with multiple nozzles with gradually reduced diameters at the discharge end, and are used for heating, guiding, pressurizing, impregnating and cooling the narrow strips; and a wire collecting reel in communication with each pultrusion device. Through the parallel process of "first dividing and then pulling", the application solves the problems of low forming freedom of the wide pre-impregnated tape, large damage and high cost in traditional wire rod preparation, and realizes efficient and low-damage continuous production of high-performance 3D printing wire rod.
