Abstract: A photo-solidification modeling apparatus and a photo-solidification modeling method, wherein the reliability of an operation for coating the upper surface of a solidified layer with an unsolidified liquid is improved and the time required to carry out the same operation is reduced. To meet the purpose, a clearance is formed between the lower surface of a recoater travelling on a solidified layer and the upper surface of the solidified layer. When this condition is satisfied, an unsolidified liquid is introduced onto the solidified layer by virtue of both the force of the lower surface of the recoater which drags the unsolidified liquid and the nature of the unsolidified liquid entering the clearance. When recesses are provided in the lower surface of the recoater, the liquid adsorbed to the surfaces of the recesses is also introduced onto the unsolidified layer.

Abstract: A photo-solidification modeling device for forming a solidified image having a desired model shape by exposing to light a liquid capable of being solidified in receipt of the light in a region corresponding to the desired model shape. Data indicative of a regularly spaced region is provided in addition to data indicative of the region corresponding to the desired model shape, and an exposure region is set according to the additional data. Accordingly, the generation of distortion of the model during the modeling process can be well suppressed without considering and inputting a position or the like of the supporting rib.
