[0003] Carbon fiber has the characteristics of high temperature resistance and continuity, and needs to be pre-impregnated with resin to prepare continuous carbon fiber composite materials that can be used for 3D printing. The existing extruders for 3D printing are generally a combination of gears and U-shaped wheels. This kind of extruder is suitable for resin materials with relatively thick diameters, such as 1.75mm or 2.85mm consumables. However, continuous carbon fiber composite materials have a relatively thin diameter, generally less than 0.5mm, which can easily break under the extrusion of the gear, resulting in extrusion failure. If a rubber wheel is used instead of a gear, the material can be protected from damage, but the rubber wheel will wear out due to its insufficient surface hardness after a long time of extrusion, and finally the extrusion will slip. Moreover, when the diameter of the continuous carbon fiber composite material is not uniform, the diameter will change from large to small in a short time, which will also cause the phenomenon of slipping.
