Abstract
A building apparatus configured to build an object includes inkjet heads serving as a plurality of ejection heads, a scanning driver, and a maintenance unit configured to perform a maintenance of the inkjet head. The scanning driver allows a plurality of inkjet heads to perform at least a main scanning operation and allows the inkjet head to perform the main scanning operation multiple times until building of the object is completed. The maintenance unit performs the maintenance of the inkjet head in an interval between two successive main scanning operations and performs the predetermined maintenance for only part of a plurality of inkjet heads in each maintenance. Hence, building with high accuracy is performed more appropriately.
