  • Photo-solidification modeling apparatus and photo-solidification modeling method having an improved recoating process
    Patent number: 5432045
    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.
