THREE-DIMENSIONAL MOLDING DEVICE

摘要

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 (30) using a recoater (2), discharging a binder from a head (1) 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 (2) is formed. so as to have an amount of sand (S) equivalent to the length of one side of the molding table (30) as the scatterable length thereof, and be capable of moving in a direction perpendicular to the one side; the head (1) 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 (30) by alternatingly operating the recoater (2) and the head (1).

主权项

1. A 3D printer using a recoater to deposit a powder material on a printing table to form layers and using printing data as the basis to discharge and coat a binder on the deposited powder material from an ink jet head and binding said powder material to create a 3D object, which 3D printer
makes said recoater a length enabling deposition of powder material in an amount of the length of one side of said printing table and forming it to be able to move in a direction perpendicular to said one side and forms said ink jet head as a line head able to discharge binder in an amount of the length of a side adjoining said one side and forming it to be able to move in a direction perpendicular to the side adjoining said one side.
