1 to 6, the 3D printer 1000 includes a light source 100, an LCD panel module 200, a water tank 300, a molding table 400, a casing 500, and a curing processor 600. can include

Here, the light source 100 is configured to provide light irradiated to the photocurable liquid resin 1 accommodated in the water tank 300 .

In such a 3D printer 1000, light emitted from the light source 100 may be irradiated to the water tank 300 via the LCD panel module 200 disposed above the light source 100.

A heat dissipation unit 110 is provided below the light source 100 . The heat dissipation unit 110 is made to effectively discharge heat generated from the light source 100 to the outside.

Further, the LCD panel module 200 transmits the light irradiated from the light source 100 in a specific form to provide light to the water tank 300 disposed above the LCD panel module 200 .

Here, the LCD panel module 200 irradiates light to an area corresponding to the slice data divided into cross-sectional layers of the 3D object to cure the photocurable liquid resin 1, thereby manufacturing a 3D object.

At this time, in the 3D printer 1000, it is preferable that the thickness of the cross-section layer of the 3D object in which the photocurable liquid resin 1 is cured is usually 100 μm, but it may be manufactured in various thicknesses other than 100 μm. Of course there is.

In addition, the molding table 400 sequentially moves the molding plate 410 in the upper direction of the three-dimensional object, that is, in the height direction, so that the uncured photocurable liquid resin 1 is moved to the lowermost surface of the water tank 300. to be positioned

Accordingly, the photocurable liquid resin 1 is sequentially cured for each slice cross-section layer on the molding plate 410, and a three-dimensional object can be manufactured.

Here, the base part 700 is configured to support and fix the water tank 300 and the LCD panel module 200 . The water tank 300 and the LCD panel module 200 may be seated on the base part 700 .

Meanwhile, the casing 500 is provided below the LCD panel module 200 .

The casing 500 has a hollow shape with an empty space formed therein. Also, the light source 100 is disposed on the inner lower portion of the casing 500 .

Also, since the heat dissipation unit 110 is coupled to the lower portion of the casing 500, heat generated from the light source 100 can be effectively discharged to the outside through the heat dissipation unit 110.

In addition, a hollow curing space 501 is provided on the inside upper side of the casing 500, and the coin processor 600 can be selectively inserted into the curing space 501. Such curing space 501 is provided between the light source 100 and the LCD panel module 200 .

In this way, since the coin processor 600 is detachable from the casing 500, for example, when manufacturing a sculpture from the 3D printer 1000, the coin processor 600 is separated from the casing 500 to light the light source. The light irradiated from (100) is guided to the water tank (300) via the LCD panel module (200). Thus, the sculpture can be manufactured in the water tank 300.

Also, when the curing processor 600 proceeds with a curing operation of the sculpture manufactured in the water tank 300, the curing operation of the sculpture may be performed while being coupled to the casing 500. That is, the user inserts the coin processor 600 into the hardening space 501 in a state in which a sculpture for a hardening operation is placed in the receiving space 601 formed inside the coin processor 600 to perform a hardening operation of the object. can proceed. At this time, in the 3D printer 1000, the light emitted from the light source 100 is irradiated onto the sculpture provided in the curing processor 600, so that the sculpture can be cured.

The coin processor 600 may include a body frame 610, a lower plate 620, a side wall plate 630, an upper plate 640, and a handle part 650.

Here, the body frame 610 forms the skeleton of the hardening processor 600.

The lower plate 620 is coupled to the lower portion of the body frame 610 and forms the bottom surface of the accommodation space 601 .

The lower plate 620 may be made of, for example, a light transmitting member such as glass capable of transmitting light so that light irradiated from the light source 100 may be guided to the receiving space 601 . Here, the lower plate 620 is not necessarily limited to glass, and any material may be used as long as light transmission is possible.

Such a lower plate 620 is made to be supported by the insertion support portion 611 provided in the lower portion of the body frame (610). That is, the lower plate 620 is made detachable from the body frame 610 through sliding movement. Therefore, for example, when the lower plate 620 of the coin processor 600 is damaged or needs to be replaced, the user can easily replace the corresponding lower plate 620 .

In addition, the side wall plate 630 is coupled to the side of the body frame 610 and forms the receiving space 601 together with the lower plate 620 . In one embodiment of the present invention, the side wall plate 630 is not made to completely cover the circumference of the side of the body frame 610 as a whole, but the side of the body frame 610 has an accommodation space 601 to communicate with the outside. A form in which the formed open hole 602 is provided will be described as an example.

In this way, when the coin processor 600 has an open hole 602 formed, a user can move a sculpture for a coin work into the receiving space 601 through the open hole 602 .

A light reflection member (not shown) may be provided on the inner surface of the side wall plate 630 . For example, when the light transmitted through the lower plate 620 of the coin processor 600 is guided to the inner surface of the side wall plate 630, the light reflecting member is provided on the inner surface of the side wall plate 630 to reflect light. The member is made to reflect the corresponding light. In this way, in the curing processor 600, the light reflected by the side wall plate 630 is irradiated onto the sculpture disposed in the receiving space 601, so that the curing operation of the sculpture can be effectively performed.

A light reflection surface (not shown) may be formed on an inner surface of the casing 500 to reflect light emitted from the light source 100, such as the side wall plate 630. Accordingly, in the case of the coin processor 600, even when the light irradiated from the light source 100 passes through the open hole 602 after passing through the lower plate 620, the corresponding light is emitted by the light reflecting surface provided on the inner surface of the casing 500. It is guided back to the receiving space 601 to harden the sculpture.

And the top plate 640 is coupled to the top of the body frame (610). The upper plate 640 together with the lower plate 620 and the side wall plate 630 form the accommodating space 601 .

Like the side wall plate 630, a light reflecting member is provided on the inner surface of the upper plate 640 so that the curing work of the sculpture disposed in the receiving space 601 can be effectively performed.

And the handle part 650 is coupled to the side wall plate 630. A user may insert the coin processor 600 into the coin space 501 or move the coin processor 600 into and out of the coin space 501 through the handle 650 .

Here, when the coin processor 600 is drawn into the coin space portion 501, it may be slid and inserted into the coin space portion 501 in a state where it is seated and supported on the mounting support portion 510 provided in the casing 500. That is, the coin processor 600 disposed in the coin space 501 is supported by the seating support 510 .

In such a 3D printer 1000, a sculpture is manufactured from one 3D printer 1000 by selectively disposing the hardening processor 600 in the space between the light source 100 and the LCD panel module 200, and at the same time The hardening treatment of the manufactured sculpture can be performed together.

FIG. 7 is a perspective view showing a coin processor according to another embodiment of the present invention. The coin processor 600' according to FIG. 7 is structurally different from the coin processor 600 according to one embodiment.

As shown in FIG. 7 , the top plate 640' provided in the coin processor 600' is detachably attached to the body frame 610. Accordingly, the curing processor 600' separates the top plate 640' from the body frame 610, places the sculpture in the accommodation space 601, and then places the top plate 640' back on the body frame. Rejoin at (610).

As the upper plate 640' is made detachable from the body frame 610, the coin processor 600' has an open hole 602 (see FIG. 6) in one embodiment. It does not need to be formed separately. Therefore, in such a curing processor 600', the side wall plate 630 may completely surround the circumference of the side surface of the body frame 610 as a whole. Alternatively, an open hole 602 may be formed in the coin processor 600'.

Of course, this curing machine is not limited to the above-mentioned embodiment, and can be configured in any shape as long as the curing operation of the manufactured sculpture can be effectively performed.

However, this is only a preferred embodiment of the present invention, and the scope of the present invention is not limited by the description scope of these embodiments.
