Abstract
A process of fabricating a three-dimensional object from a light curable liquid resin includes irradiating a light to a surface of the light curable liquid resin so as to form successive cross-sectional layers of the cured resin at that surface and to superimpose the successive layers on each other. An improvement resides in that one or more of the successive layers is made to have different portions made through different curing conditions. By providing such cross-sectional layers having different curing conditions, the resulting three-dimensional object can be made into accurate outer configuration without leaving any critical residual stress therein.
