Abstract: The present disclosure relates to a 3D printer for construction for printing and forming various structures, in which agitating blades 45 capable of auto-rotation are mounted inside a nozzle 10 discharging a printing material such as concrete or mortar, to thereby enable agitation of a fluid printing material inside the nozzle 10.
According to the present disclosure, agitation of the fluid printing material inside the nozzle 10 of 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.

Abstract: The present disclosure relates to a 3D printer for construction for print-molding various structures, in which a main pipe 30 for transferring a filament material 31 therein is installed inside a nozzle 10 for discharging a printing material, such as concrete or mortar, to enable co-printing of the filament material 31 with 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 material 31 as 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.
