An additive manufacturing apparatus includes a table, an ejecting unit that faces the table and ejects photocurable droplets toward the table, a light-applying unit that applies light to and cures thedroplets that is ejected from the ejecting unit and falls on the table, a moving unit that moves the table back and forth along with the light-applying unit and relative to the ejecting unit, and a controller that controls the ejecting unit, the light-applying unit, and the moving unit such that the ejecting unit ejects droplets toward the table while the table is moved relative to the ejecting unit; the light-applying unit applies, when a direction of relative movement of the table is changed, light to the droplets that have moved together with the table out of an area where the table facesthe ejecting unit; and a three-dimensional object is formed as a stack of layers composed of the droplets that have been cured. 本发明提供种增材制造设备，其包括：工作台；喷射单元，其面对所述工作台并且朝向所述工作台喷射可光固化液滴；光施加单元，其向从喷射单元喷射出并落在工作台上的液滴施加光而使液滴固化；移动单元，其使工作台
