PURPOSE:To feed efficiently a photocurable resin on an unexposed face without requiring a pump and a dipper by an apparatus wherein the photocurable resin is automatically fed from a storing tank to an outer liq. tank accompanied with lowering of a base stage through a screw shaft and it is made to flow down into an inner liq. tank and it is made smooth by means of a doctor blade to form an exposing layer on the base stage. CONSTITUTION:In a method wherein a three dimensional body is formed by laminating cured layers, an outer tank 1, an inner forming tank 2 formed by covering with a partition wall consisting of bellows 3 and 3' stretching and shrinking around a base stage 4 being movable up and down in the upper part of this outer tank 1, and a storing tank 30 between a stretching and shrinking partition wall 3', the outer tank 1 and the bottom wall in the lower part of the base stage 4 of this inner forming tank 2 are integrally provided. An outer liq. tank 40 formed on the upper part of the periphery of the outer tank 1 is communicated with this storing tank 20 through a freeding pipe 33. The photocurable resin is automatically fed from a storing tank 30 to an outer liq. tank 40 accompanied with lowering of a base stage 4 through a screw shaft and it is made to flow down into an inner liq. tank and it is made smooth by means of a doctor blade 22 to form an exposing layer on the base stage 4. |
