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.
