Abstract
The present invention provides a three-dimensional molding device which makes it possible to reduce molding time by decreasing the inkjet head waiting time during the molding step. A three-dimensional molding device for scattering and layering sand on a molding table () using a recoater (), discharging a binder from a head () so as to coat the top of the scattered sand with the binder, on the basis of molding data, and creating a three-dimensionally molded article by joining the sand (S) using the binder, wherein: the recoater () is formed so as to have an amount of sand (S) equivalent to the length of one side of the molding table () as the scatterable length thereof, and be capable of moving in a direction perpendicular to the one side; the head () is formed as a line head capable of discharging an amount of the binder equivalent to the length of a side adjacent to the one side, and so as to be capable of moving in a direction perpendicular to the side adjacent to the one side; and the three-dimensionally molded article is formed on the molding table () by alternatingly operating the recoater () and the head ().
