Abstract
A device for manufacturing a three-dimensional shaped object includes a table on which a layer of granulated powder is stacked, a layer formation portion that forms the granulated powder on the table into a layer having a predetermined thickness, a compression unit configured to compress the layer to crush the granulated powder in a formation region of a three-dimensional shaped object in the layer, and a binder applying unit that forms a shape of the three-dimensional shaped object by applying the binder to only a region corresponding to the surface region of the three-dimensional shaped object, in the formation region in the layer.
Claims7
A device for manufacturing a three-dimensional shaped object comprising:
- a table having a surface configured for receipt of a granulated powder;
- a leveling device that is configured to a level the granulated powder positioned on the surface of the table into a layer having a predetermined thickness;
- a roller configured to compress the layer such that the predetermined thickness is reduced to a lesser thickness that is located in a formation region of a three-dimensional shaped object in the layer;
- and
- a binder applying unit that forms, in the formation region in the layer, a shape of the three-dimensional shaped object by not applying a binder to a region not corresponding to a surface region of the three-dimensional shaped object and by applying the binder to a region corresponding to the surface region of the three-dimensional shaped object.
A method for manufacturing a three-dimensional shaped object comprising:
- depositing a granulated powder onto a table;
- leveling the granulated powder on the table into a layer having a predetermined thickness;
- compressing the layer having the predetermined thickness to a lesser thickness that crushes the granulated powder in a formation region of a three-dimensional shaped object in the layer;
- forming a shape of the three-dimensional shaped object by not applying a binder to a region not corresponding to a surface region of the three-dimensional shaped object and by applying the binder to a region corresponding to the surface region of the three-dimensional shaped object, in the formation region in the layer;
- and
- a sintering step of sintering the three-dimensional shaped object formed in the binder application step.
