The concrete 3D printing system generally comprises an analog control part, a mechanical movement part and a raw material stirring and conveying part. When printing, after the analog control part sends out instructions, the mechanical movement part performs closed movement layer by layer according to the established model, and the concrete material is continuously conveyed to the designated position at the moment. The concrete material is extruded like toothpaste and then piled up layer by layer until the printing process is finished, and in order to improve the 3D printing effect of the concrete, thin-strip-shaped glass fibers are added into the concrete, and a concrete 3D printer nozzle is an important component for 3D printing of the concrete and mainly comprises a storage barrel, a nozzle, a feed pipe, a barrel opening, a spiral blade and the like. However, when the existing concrete 3D printer nozzle is used, the glass fibers are easy to agglomerate, if the glass fibers are not filtered and cleaned, the nozzle is easy to be blocked, the glass fibers in the concrete are uneven, the printing quality is affected, at the moment, a filter screen can be adopted for filtering, but the filter screen is inconvenient to clean and break up the fiber clusters filtered on the filter screen, the filter efficiency of the filter screen is poor, the concrete is difficult to pass through the filter screen, and the glass fibers are uneven and still affect the printing effect.
