The present disclosure relates to a 3D printer for construction for printing and forming various structures, in which agitating bladescapable of auto-rotation are mounted inside a nozzledischarging a printing material such as concrete or mortar, to thereby enable agitation of a fluid printing material inside the nozzle According to the present disclosure, agitation of the fluid printing material inside the nozzleof the 3D printer for construction may be facilitated to prevent material segregation and maintain a homogeneously mixed state of materials constituting the fluid printing material.

Nozzle of auto-agitating type 3D printer for construction

The present disclosure relates to a 3D printer for construction for print-molding various structures, in which a main pipefor transferring a filament materialtherein is installed inside a nozzlefor discharging a printing material, such as concrete or mortar, to enable co-printing of the filament materialwith the printing material while embedded in the printing material. According to the present disclosure, in constructing a structure by a 3D printer for construction, a printing material embedded with the filament materialas reinforcing material may be printed, and as a result, the effects of reinforcing tensile strength of the printed object and inhibiting crack of the printed object may be obtained.
