Abstract
A photocurable composition is supplied onto an auxiliary table provided to be capable of being adjacent to a fabrication table. One of the fabrication table and the auxiliary table is moved relative to the other one of the fabrication table and the auxiliary table in an up-and-down direction. The photocurable composition that has been supplied to the auxiliary table is drawn and spread by a recoater on a fabrication surface of the fabrication table or on a cured composition layer. The photocurable composition on the fabrication surface of the fabrication table is exposed by an exposure device, so that a cured composition layer is formed.
