The first discharge portion 242 or the second discharge portion 252 on which the material storage device ST of the desired material and color is stored is mounted on the corresponding head W Are moved to the desired positions by the left and right motions (X axis direction) along the vanes W242 and W252. In addition, the accuracy of the position is enhanced by fine adjustment of the head HD. That is, according to the present invention, the three-dimensional printed matter is formed by the up-and-down and back-and-forth motions of the plate PL and by the right and left motions of the head HD.

Consequently, the three-dimensional printed matter is formed by the discharge of the material in the head (HD) connected to the material storage ST containing the material of the material and the color desired by the user.

Fig. 5 shows a front view of a three-dimensional printer 300 according to the third embodiment of the present invention. However, in FIG. 5, some configurations are omitted.

As can be seen from FIG. 5, the three-dimensional printer 300 according to the second embodiment of the present invention includes all the components of the three-dimensional printer 200 according to the second embodiment of the present invention. In the three-dimensional printer 300 according to the third embodiment of the present invention, the first discharging portion 341 and the second discharging portion 352 located below the wings W341 and W351 of the second material supplying portion 351, respectively, One ends W342 and W352 of the vanes 342 and the second discharge portion 352 are connected to one ends of the vanes W341 and W351 of the first material supply portion 341 and the second material supply portion 351, The configuration of the 1-1 linking member 360 and the 2-1 linking member 370 are the same as those of the 3D printer 200 according to the second embodiment of the present invention, The configuration of the other end of the vanes W341 and W351 of the second material supply unit 351 is different as follows.

The other end of the wing W341 of the first material supply unit 341 is connected to the first support member 310 and the second connection member 380 is connected to the wing W341 of the first material supply unit 341, And the other end of the wing W342 of the first discharge portion 342 is connected to the other end of the first material supply portion 341. [ The other end of the wing W351 of the second material supply portion 351 is connected to the second support member 320 and the second-second connection member 390 is connected to the wing W351 of the second material supply portion 351, The second point of the second material supply portion 351 spaced apart from the other end of the second discharge portion 352 is connected to the other end of the wing W352 of the second discharge portion 352. [

As described above, the three-dimensional printers 100, 200, and 300 of the preferred embodiments of the present invention are summarized as follows.

(1) The three-dimensional printed matter is formed by the up-down movement and the back-and-forth motion of the plate PL and the left and right movement of the head HD.

Since the head HD only needs to be moved in the left and right directions during the formation of the three-dimensional printed matter, the first ejection portions 142, 242 and 342 and / or the second ejection portions 252 and 352 Since it requires only up and down movement and back and forth movement of one plate PL without involving vertical movement and back and forth movement, it can be implemented simply by hardware and control is also simple.

For example, when the first discharging portions 142, 242, 342 and / or the second discharging portions 252, 352 move up and down, the first discharging portions 142, 242, 342 and / If only one wing (W142, W242, W342, W252, W352) included in the discharging portions 252, 352 is caused to move up and down, the three- The wings W142, W242, W342, W252 and W352 return to their original positions and the other wings W142, W242, W342, W252 and W352 have to move to the printing position of the three-dimensional printed matter .

When all the vanes W142, W242, W342, W252 and W352 included in the first discharging portions 142, 242 and 342 and / or the second discharging portions 252 and 352 are caused to move up and down simultaneously, (W142, W242, W342, W252, W352), it becomes difficult to control the motor.

Therefore, when the plate PL is controlled to move up and down, the troubles of controlling the plurality of blades (W142, W242, W342, W252, W352) are simplified.

(2) When the first discharging portions 142, 242, and 342 and / or the second discharging portions 252 and 352 move up and down, the first connecting member 160, 260 and 360, The first and second connecting members 270 and 370 and the first and second connecting members 380 and 390 are connected to the first and second discharging units 142 and 242 and / 252, and 352 need to form a long pillar for making a path capable of vertical movement. Accordingly, since the three-dimensional printed matter must be formed in the space constituting the column, the space for forming the actual three-dimensional printed matter becomes relatively narrow. Further, the first to fourth connecting members 160, 260 and 360, the second-first connecting members 270 and 370, the first-second connecting member 380 and / or the second- The distance in which the head HD can move left and right is also reduced, and the space for forming the actual three-dimensional printed matter becomes relatively narrow.

On the other hand, when the plate PL is controlled to move up and down like the present invention, the first to-1 connecting members 160, 260 and 360, the 2-1 connecting members 270 and 370, The coupling members 160, 260, 360, and 360 do not need to form long poles and the distance of the head HD can be moved left and right, There is a problem that the space for forming the actual three-dimensional printed matter by the second-second connecting members 270 and 370, the first-second connecting member 380 and / or the second-second connecting member 390 is reduced I never do that.

(3) When the first and second discharging units 142, 242, and 342 and / or the second discharging units 252 and 352 move up and down, the material storage ST connected to the head HD and the head HD, The bubbles may be generated or fluctuated in the material contained in the head HD and the material reservoir ST due to the movement of the nozzle.

On the other hand, when the plate PL is controlled to move up and down like in the present invention, problems such as bubbles or fluctuations in the material contained in the head HD and the material storage ST can be minimized.

As described above, according to the three-dimensional printer 100, 200, and 300 of the preferred embodiments of the present invention, it is understood that a three-dimensional printed material including various materials and colors can be easily manufactured.
