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.

Three-dimensional object manufacturing method and three-dimensional object manufacturing system

A building apparatus building a three-dimensional object includes: an inkjet head serving as an ejection head; and a scan driver. The scan driver causes the inkjet head to perform a main scanning operation and a sub scanning operation. In an operation of forming one layer, the scan driver causes the inkjet head to perform the main scanning operation a certain number of times Pn (Pn is an integer equal to or greater than two), for each position of the layer being built, and to form, as the one layer, a layer configured such that a plurality of blocks formed by performing the Pn main scanning operations are arranged in a row in a sub scanning direction. Each of the blocks includes an intermediate region and an end region. The manner of forming the end region in the corresponding block is differentiated between two layers continuously overlapping in the deposition direction.
