THREE-DIMENSIONAL OBJECT MANUFACTURING METHOD AND THREE-DIMENSIONAL OBJECT MANUFACTURING SYSTEM
First Claim
1. A three-dimensional object manufacturing method, comprising:
- providing a three-dimensional object manufacturing device, including;
an inkjet head for forming an ink layer;
a flattening mechanism for removing one part of a surface of the ink layer formed by the inkjet head to flatten the surface and adjust a thickness of the ink layer to a specific thickness; and
a controller for layering and stacking the ink layer in which the surface is flattened by the flattening mechanism to manufacture a three-dimensional object;
performing an ink ejection amount reducing step of forming an ink ejection amount reduction region in which an ejection amount of ink ejected by the inkjet head is reduced from an amount corresponding to the specific thickness in at least one part of a part corresponding to an interior of the three-dimensional object, when forming the ink layer that is specific with the inkjet head; and
performing an ink ejection amount increasing step of increasing an ejection amount of ink ejected by the inkjet head with respect to a region in which a range in an extending direction of the ink layer overlaps the ink ejection amount reduction region from an amount corresponding to the specific thickness, when forming the ink layer on an upper side of the ink layer that is specific with the inkjet head.

Abstract
In a three-dimensional object manufacturing method using a three-dimensional object manufacturing device for manufacturing a three-dimensional object by layering and stacking an ink layer in which a surface is flattened by a flattening roller for removing one part of the surface of the ink layer to adjust a thickness of the ink layer to a thickness t, where when forming ink layers with an inkjet head, an ink ejection amount reduction region in which an ejection amount of ink ejected by the inkjet head is reduced from an amount corresponding to the thickness t in a part corresponding to an interior of the three-dimensional object, and when forming the ink layers on an upper side of the specific ink layers with the inkjet head, an ejection amount of ink ejected by the inkjet head is increased from an amount corresponding to the thickness t.
