PROBLEM TO BE SOLVED: To uniformly disperse again a semisolid accumulated at the bottom by providing an open part on part of a resin tank, and forming a circulating path between the open part and a surface part of photocurable resin, and further, forming a stirring means for stirring the photocurable resin and a transfer/discharge means for transferring the photocurable resin and discharging it to the surface part in the circulating path. SOLUTION: When this optical shaping device is started, a semisolid 15 formed of an accumulated reinforcing material is extruded from an open part 18, together with photocurable resin 2 of lower density than the semisolid 15, by a transfer/ discharge means 17, and these materials are moved into the stirring means 21. In the stirring means 21, both semisolid 15 and photocurable resin 2 are stirred by the powerful rotating force of a stirring blade 20 driven by a motor 19 to be uniformly dispersed. On the other hand, the transfer/discharge means 17 repeats the same action and consequently, the photocurable resin 2 dispersed in the stirring means 21 is discharged on the surface part of the photocurable resin 2 from a discharge aperture 23 by a pressure generated by the movement of the transfer/discharge means 17. Thus the surface is made uniform by the shuttle motion of a liquid level sweeping means 34 in the direction (f). |
