    Abstract: The present invention relates to a 3D printer for construction for printing and forming various structures, in which a spray pipe 60 follows a nozzle 10 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.
