Optical fabricating apparatus and optical fabricating method

An optical fabricating apparatus that manufactures a three-dimensional fabrication object by stacking cured composition layers in an up-and-down direction, comprising:

• a fabrication table that has a fabrication surface;
• an auxiliary table provided to be capable of being adjacent to the fabrication table;
• a relative mover that moves one of the fabrication table and the auxiliary table relative to another one of the fabrication table and the auxiliary table in the up-and-down direction;
• a supplier that supplies a photocurable composition onto the auxiliary table;
• a spreader that draws and spreads the photocurable composition that has been supplied onto the auxiliary table by the supplier on the fabrication surface of the fabrication table or on an upper surface of the cured composition layer from an upper surface of the auxiliary table with the upper surface of the auxiliary table positioned at a same height as the fabrication surface of the fabrication table or the upper surface of the cured composition layer;
• and
• an exposure machine that exposes the photocurable composition on the fabrication surface of the fabrication table to form the cured composition layer.
