Abstract
A nozzle-replaceable printing head for continuous fiber printing and a printing method are provided. The printing head includes a fixed bracket, a wire feeding module located at an upper part of the structure, an upper guide pipe, a shearing module located at a middle part of the structure, a lower guide pipe, a heat dissipation sleeve, a throat pipe, a heating coil, and a nozzle module located at a bottom of the structure, where a continuous fiber reinforced thermoplastic resin matrix pre-impregnated composite wire coaxially penetrates through the other side of the printing head from top to bottom and is fed for printing. An adjustment groove with scales is configured to standardize adjustment on clamping and feeding states of pre-impregnated composite wires of different specifications.
