1, a drive control unit 12 that fetches data from the host computer 11 and controls each part according to the data, an XY direction for controlling the ejection position and direction of the photocurable resin according to a control signal from the drive control unit 12 Movement control device 13, turning movement control device 14, and Z-direction movement control device 15, inkjet heads 16 to 21, resin tanks 22 to 24, pump 25 to
It comprises a molding stage 31, a resin curing light source 32. To explain the operation of this apparatus, the three-dimensional model formed by the host computer 11 is sliced into a number of thin cross-sections, and each cross-section is converted into coordinate data. The color is converted into color data according to the model color. When this data is transferred to the drive control unit 12, the XY
The direction movement control device 13, the turning movement control device 14, and the Z direction movement control device 15 are operated, and the inkjet heads 16 to 21 are operated.
Then, the molding stage 31 located above this moves to a predetermined position. After the movement, the ink jet heads 16 and 21, or 17 and 20, or 18 and 21, or 16, 17, 20, and 2 from the host computer 11 via the drive control unit 12.
A command is issued to 1, or 17, 18, 19 and 20 or all ink jet heads and the corresponding tanks 22 are pumped.
The photocurable resin contained in # 24 is discharged. Each of the tanks 22 to 24 contains a photo-curable resin of a different type or a different color, and as a result, it is possible to form a molded article made of a plurality of types of resins or to make the resin into any color. The droplets of the photocurable resin discharged from the ink jet head are stacked one by one on the molding stage 31, and then the resin is cured by irradiation of the light source 32.
By repeating the above-described ejection from the ink jet heads 16 to 18 at the lower position and the ink jet heads 19 to 21 at the side position, a molded product made of various kinds of resins, or a molded product of multiple colors or an arbitrary mixed color is formed. Is done.

くかかることになる。However, in this three-dimensional molding apparatus, when the photocurable resin droplets discharged toward the molding stage surface are radicalized by the light energy from the light source, the presence of oxygen in the air suppresses the radical polymerization. Delays light curing. As a result, the light energy loss is increased, which is inefficient. In other words, since the ejection of the photocurable resin and the curing by light irradiation are repeated and this process is repeated, if the photocuring is inefficient, it takes a long time to form a three-dimensional molded product.

ズに進むこととなる。The operation of this apparatus is substantially the same as the operation of the above-described ink-jet type three-dimensional molding apparatus. However, it is characterized in that the inside of the chamber 33 is previously evacuated by the vacuum pump. In this way, when the photocurable resin is discharged toward the molding stage in the chamber and is photocured by light irradiation from a light source, radical polymerization accompanying radicalization of the resin droplets may cause obstacles such as oxygen gas. No, it will proceed smoothly.
