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.

Abstract: The present invention relates to a 3D printer for construction for printing and forming various structures wherein a roller 50 follows a nozzle 10 which discharges concrete, mortar, or the like, to bring an outer peripheral surface of the roller 50 to be in close contact with a surface of the printed object, and thus the surface of the printed object is flattened.
According to the present invention, a high-degree surface flattening work can be performed on the surface of a printed object simultaneously as the printed object is printed by a 3D printer for construction, thus enabling rapid and reliable flattening of the printed object and smooth surface forming.-

Abstract: The present invention relates to a 3D printer for construction for printing and forming various structures, in which a spray pipe follows a nozzle for discharging concrete or mortar, and sprays a liquid material onto the surface of a printed object, thereby enabling the liquid material to be applied on the surface of the printed object. Through the present invention, the printing of the printed object and the spraying of the liquid material onto the surface of the printed object may be carried out simultaneously by means of the 3D printer for construction, and thus a rapid and uniform coating treatment of the printed object is possible, and an adequate wet state of the tissue of the printed object may be maintained.

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.
