Beschreibung
Zusammenfassung:	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.
