Abstract

In one method, a base for supporting a cured object is brought into close contact with or close to an aperture of a container so as to remove the bubbles therebetween. When one layer is formed, parts of the layer may be successively formed, wherein the base is moved back and forth to separate each part. Also, the aperture or container with the aperture may be inclined relative to the base to separate the layer from the aperture.
