  • Patent number: 5780070
    Abstract: There is provided an apparatus for solidifying and shaping fluid which can be optically cured, including (a) an optically scanning device for scanning a level of fluid which can be optically cured, with a light beam, (b) a sinking device for sinking a layer having been cured by scanning carried out by the optically scanning device, below a level of the fluid, and (c) a recoat device for covering a cured layer having been sunk in the step (b), with a fluid which is not yet cured. The recoat device is formed with a recoater blade which horizontally moves above a level of the cured layer with a predetermined gap kept therebetween to smooth a level of the not yet cured fluid. The optically scanning device scans a level of not yet cured fluid having been smoothed by the recoater blade, with a light beam, simultaneously with scanning of the optically scanning device.
