OPTICAL FORMING APPARATUS FOR FORMING THREE-DIMENSIONAL OBJECTS

摘要

An optical forming apparatus which can form a homogeneous three-dimensional object exhibiting desired properties over all parts, while effectively suppressing sedimentation of filler even though the filler is easily precipated in a photo-curable resin composition. The optical forming apparatus can produce a three-dimensional object consisting of laminated layers of cured resin produced by repetition of forming cured resin layers by selectively irradiating a photo-curable liquid resin composition placed in a container (20), wherein the apparatus is characterized by having a means (60) for circulating the photo-curable liquid resin composition.
