US 2016/0107387 A1 · THREE-DIMENSIONAL FABRICATING APPARATUS AND METHOD OF FABRICATE THREE-DIMENSIONAL SHAPED OBJECT

Abstract

A three-dimensional fabricating apparatus has a table on which a powder material is stacked in a layered manner, and a shaping unit which includes a powder material supply device supplying the powder material onto a top surface of the table by every predetermined layer thickness and a binder liquid supply device ejecting a binder liquid to the powder material supplied onto the top surface of the table. The powder material supply device of the shaping unit is movable in one direction in a state adjacent to the top surface of the table and is capable of supplying the powder material onto the top surface of the table at a predetermined supply width while moving the powder material supply device. The binder liquid supply device is capable of moving in the same direction as the powder material supply device in a state adjacent to the top surface of the table.

A three-dimensional fabricating apparatus comprising:

a table on which a powder material is stacked in a layered manner;
and
a shaping unit which includes a powder material supply device supplying the powder material onto a top surface of the table by every predetermined layer thickness and a binder liquid supply device ejecting a binder liquid to the powder material supplied onto the top surface of the table so as to bind the powder material,
wherein the powder material supply device of the shaping unit is movable in one direction in a state adjacent to the top surface of the table and is capable of supplying the powder material onto the top surface of the table at a predetermined supply width while moving the powder material supply device, and
the binder liquid supply device is capable of moving in the same direction as the powder material supply device in a state adjacent to the top surface of the table, is capable of ejecting the binder liquid to the top surface of the table at the same ejection width as the powder material supply width of the powder material supply device in maximum, and is capable of moving and ejecting the binder liquid to the powder material supplied onto the top surface of the table in accordance with the movement of the powder material supply device.
