″性樹脂６６は、液体から固体に変化して硬化する。A three-dimensional model created with CAD is sliced into many thin cross-sections. According to this data, the control computer 61 operates the XY-direction movement control device 62 and the Z-direction movement control device 63, and at the same time a laser beam is irradiated from the laser light source 64 to move the liquid surface of the photocurable resin 66 in the resin tank 65. 67 to control computer 6.
A cross-sectional shape based on the information in 1 is drawn. Photocuring with a laser beam on a table 68 in a tank 65
The resin 66 changes from a liquid to a solid and hardens.
これによって一層分の断面体が作り出される。This creates a cross-section of one layer.

樹脂の重合の制御をすることも非常に困難である。[Problems to be Solved by the Invention] However, the above-mentioned conventional apparatus has a structure in which the photocurable resin is in liquid form in a tank, and is cured by irradiating it with a laser beam. It can only be made from one material. If we were to change the material during molding, we would have to replace all of the photocurable resin in the tank and perform cleaning and other operations, which would take more time and money than necessary. It is also very difficult to control the polymerization of the resin.
