Abstract: 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.
