Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the drawings.

5 is a schematic diagram illustrating the configuration of a 3D printing system of a non-trim type external panel according to an embodiment of the present invention.

5, the 3D printing system of the unshrouded external panel according to the exemplary embodiment of the present invention includes a form module 100, a height adjustment control unit 200, and a 3D printing apparatus 500.

The MPF (Multi-Point Forming) apparatus according to the present invention includes a plurality of height adjustment members 130 disposed adjacent to each other, and adjusts the individual height by moving the height adjustment member 130 up and down. Preferably, the height adjustment member 130 receives shape height information from the three-dimensional model.

The mold module 100 according to the present invention forms an irregular bending shape of a forming plate 110 disposed on a height adjusting member 130 of an MPF (Multi-Point Forming) apparatus.

The height adjustment control unit 200 according to the present invention is connected to the height adjustment member 130 at a lower portion of the form module 100 to drive the height adjustment member 130 to be individually moved up and down, And the molding plate 110 is adsorbed on the upper side of the height adjusting member 130 by the reduced pressure of the connected air pump 220.

The 3D printing apparatus 500 according to the present invention prints an irregular outer panel material on the molded plate 110.

The molding plate 110 according to the present invention is preferably made of a flexible material. Elasticity and stretchability in order to form an irregular shape by controlling the height of each point by the height adjustment control unit 200 of the molding plate 110.

7, the lower side of the forming plate 110 is formed in a shape corresponding to the upper side of the height adjusting member 130, so that the forming plate 110 is disposed on the lower side of the height adjusting member 130 And more preferably in close contact with the upper side.

The shaping plate 110 may be freely formed in the form of an amorphous panel to be fabricated and has an appropriate thickness so that the shape or level of the end portion of the height adjusting member 130 does not affect the surface quality of the 3D printing. This is because the irregular external panel shape according to the BIM model 610 can be realized if external force is applied at a specific point by each height adjusting member 130 and the height of each point is clearly classified.

The mold plate 110 adsorbed to each height regulating member 130 is guided by the height regulating controller 200 to the height adjusting member 100 of the mold module 100 according to the atypical external panel shape information obtained from the BIM model 610, The height of the plate 130 is adjusted so that the closely-formed plate 110 is formed into a preformed plate of an unshrouded external panel.

However, in the case where a desired irregular shape does not require air adsorption of the molding plate 110, or when a metal plate other than an irregular exterior panel is molded through the MPF apparatus, the step of adhering the molding plate by the air pump may be omitted Of course it is.

The height adjustment control unit 200 may include a controller 210, an air pump 220, a servo motor and a deceleration unit 230, and a power supply unit 240.

The controller 210 controls the entire height controller 200.

The air pump 220 draws the air inside the form module 100 and causes the forming plate 110 to be adsorbed on the height adjusting member 130.

The servo motor and the deceleration unit 230 are individually associated with the respective height adjusting members 130 to move them up and down.

The power supply unit 240 supplies power to the control unit 210, the air pump 220, and the servo motor and the deceleration unit 230.

The connection of the air pump 220 to the form module 100 in the present invention is for bringing the molding plate 110 disposed on the height adjusting member 130 into close contact with the height adjusting member 130.

The height of each height adjusting member 130 is clearly classified by the vertical movement of the height adjusting member 130 by being adsorbed (closely attached) to the forming plate 110 at each point, This is because the shape can be precisely implemented.

The mold module 100 and the air pump 220 are connected to communicate with each other through air. As shown in FIG. 5, the entire mold module 100 may be connected to the air pump 220 in a reduced pressure or vacuum state . 6, a hollow tube 131 is formed in each of the height adjusting members 130 so that the air pump 220 sucks air through each hollow tube 131, Or may be connected at the end of the forming plate 110 by sucking it.

The type of the molding plate 110 and the air depressurizing method according to the present invention will be concretely summarized as follows.

The following two embodiments of the type of the molding plate 110 according to the present invention are possible.

First, there is a molded plate type of elastic pad which encloses the height regulating member 130 while sealing the form module 200 as a whole (refer to FIG. 5). This is referred to below as "molded plate type 1 ". When the air tightness is good, the air adsorption is effectively performed in the closed inside.

Secondly, there is a molded plate type that is disposed only on the upper side of the height adjusting member 130. In this case, since the side surface of the height adjusting member 130 communicates with the periphery, the form module 100 is not entirely closed. This is hereinafter referred to as "molded plate type 2 ".

The following two embodiments of the air depressurization method according to the present invention are possible.

First, there is a method of extracting air between the adjacent height adjustment members 130 by using the air pump 220. This is hereinafter referred to as "air decompression method 1 ".

Second, a hollow tube 131 is formed in the height adjusting member 130, and the hollow tube 131 and the air pump 220 are connected to each other to extract air from the hollow tube 131 6). This is hereinafter referred to as "air decompression method 2 ".

The combination of the mold plate type and the air decompression method is as follows.

In the case of the molded plate type 1, both the air decompression method 1 and the air decompression method 2 are applicable. For mold plate type 2, the air decompression method 2 is applicable.

In the case of the molded plate type 1 and the molded type 2, the lower side of the molded plate is provided in a shape corresponding to the upper side of the height adjusting member 130 so that the molded plate 110 is more closely attached to the upper side of the height adjusting member 130 And is more preferable in that it is disposed.

The 3D printing apparatus 500 according to the present invention includes a first 3D printing apparatus 510 for printing the outer edge of a printing zone on a forming plate 110 whose height is set by a height adjustment controller 200 of a forming plate 110, And a second 3D printing device 530 that prints the printed outer envelope interior area.

The application of the 3D printing device in this way is intended to solve the problem that it is difficult to precisely print a concrete material when the concrete material is overflowed out of the shape of the irregular external panel.

That is, by printing the outer edge of the irregular outer panel shape with a sticky material with a predetermined thickness by the first 3D printing apparatus 510 and then printing the inside of the outer frame by the second 3D printing apparatus 530, This is because 3D printing of irregular external panels can be done precisely.

More specifically, the rapid curing material is first printed by the first 3D printing apparatus 510 to secure the outer frame, and then the second 3D printing apparatus 530 forms the outer panel material, that is, the outer panel (Special concrete or the like) which can secure the strength of the concrete.

Rapid curing materials are materials that can be cured early such as plastic materials. By using a material with a short curing time, such as a plastic material, it is possible to mold the outer frame of the irregular external panel shape. This is because, when 3D printing of the atypical external panel body portion is performed later, the printing material can be prevented from flowing out of the shape, so that the irregular external panel can be formed quickly and stably.

In the present invention, the molding plate 110, the height adjustment control unit 200, and the 3D printing apparatus 500 are controlled in accordance with the shape information of the BIM (Building Information Modeling) model of the atypical external panel modeling the three- And an integrated controller (600).

The shape information for outputting the outer frame according to the shape of the atypical external panel through the 3D scanner 400 is obtained by matching the shape according to the BIM model and the shape shown in the actual molding plate 110, In order to determine the precise position of the output of the shape of the irregular external panel. This process is called surface-based registration.

The integrated controller 600 according to the present invention controls the driving of the height adjustment controller 200 to mold the surface shape of the molding plate 110 of the atypical external panel, A 3D scanner 400 for obtaining accurate position information for outputting an irregular outer panel on the plate 110 and a 3D printing device 510 and 530 for performing 3D printing of the irregular outer panel shape according to the BIM model 610 Can be controlled.

3, in the embodiment of the present invention, a molding plate 110 fixed in the form of an irregular external panel by the height pressure control unit 200 of the forming plate 110 is formed by using the 3D scanner 400 The exact position to output the shape of the atypical panel on the molding plate can be grasped by matching the shape according to the BIM model and the shape shown in the actual molding plate 110 by scanning.

FIGS. 8 and 9 are schematic views of the forming plate 110 as a stretchable pad in which the forming plate 110 surrounds and seals the height adjusting member 130 according to another embodiment of the present invention.

Fig. 8 is a schematic view of forming a convex molding plate without air adsorption.

9 (a), when a concave shape is to be formed in a concave shape or a complicated shape, the height of the periphery is set high, so that the concave center portion is formed by the height adjustment member 130, so that there is a possibility that a desired irregular shape can not be realized.

In this case, as shown in FIG. 9 (b), the molding plate 110 is depressurized by using the air pump 220 connected to the height adjustment control unit 200, so that the upper side of the height adjustment member 130 So that a desired irregular bending shape can be realized. After that, the 3D printing operation can be performed precisely and stably through the material such as concrete, and it becomes possible to produce high-quality unshaped external panel.

Hereinafter, a 3D printing method of a non-seamless external panel will be described step by step as another embodiment of the present invention.

The molding plate 110 having a high elasticity and durability is placed in the mold module 100 and the height adjusting member 130 and the molding plate 110 are brought into close contact with each other through the air pump 220 as required. The forming plate 110 closely attached to each height adjusting member 130 is moved to a height of the form module 100 according to the irregular external panel shape information obtained from the BIM model 610 by the height adjusting control unit 200 of the forming plate 110 The height of the regulating member 130 is adjusted so that the closely-formed molded plate 110 is molded into the shape of a molded plate of an unshrouded external panel.

As described above, the height of the forming plate 110 can be adjusted by using the height adjusting control unit 200 and the air pump 220 according to need, It can be easily formed into a molded plate shape, and then the shape of the molded plate 110 for stable 3D printing can be set.

The present invention includes a step (b) of scanning the forming plate 110 with the 3D scanner 400 to obtain position information on the molding plate 110 to output a non-trimmed outer panel. This is a step of acquiring positional information for outputting the atypical external panel on the forming plate 110 by scanning the forming plate 110 set along the height of the height adjusting member 130 by the 3D scanner 400.

After the forming plate 110 is set in the shape of an irregular external panel by the height pressure control unit 200, the forming plate 110 is scanned through the 3D scanner 400 or the 3D laser scanner, and the outer edge of the non- As shown in FIG.
