PROBLEM TO BE SOLVED: To provide a photo-fabrication device in which solid moldings with good precision are formed by stably holding the state of a liquid level of photo- setting resin liquid attendant on elevating and lowering action of an elevating/ lowering stage. SOLUTION: The photo-fabrication device 10 is equipped with a resin tank 14 holding photo-setting resin liquid 12, an elevating and lowering stage 20 which is arranged in the resin tank 14 and held by four pieces of arms 16 and elevated/lowered in a horizontal state, a table plate 22 placed on the elevating/ lowering stage 20 and an optical beam irradiation device 24 for curing the liquid level of photo-setting resin on the table plate 22 by irradiation of optical beam. For example, a cylindrical-type weight 30 in which volume of the upper part is larger in comparison with the lower part and diameter is different, is provided as the weight for regulating liquid level by which rocking of liquid level of photo-setting resin liquid 12 is stabilized. Thereby, the state of liquid level of photo-setting resin liquid 12 is always stably held. Therefor, formation of solid moldings with good precision is enabled. Further, since time necessary till liquid level is stabilized, is shortened, fabrication time is shortened and a cost necessary for fabrication is reduced. |
