The types are also very broad across all industries, and the outlook for the 3D printer market is very bright.

Meanwhile, conventional 3D printers are classified into a solid type method for outputting a print using only a solid printing material and a liquid type method for outputting a print using only a liquid printing material according to the printing material used for output. However, these conventional solid-state and liquid-type 3D printers require a separate cumbersome processing operation to mix solid and liquid, and the material of the printing material used is limited to solid or liquid, so the types of products that can be mass produced are used in all industries. There is a problem that it is difficult to reflect the demands of the 3D printer market that is broad across the field.

In addition, in recent years, attempts have been made to manufacture electronic-related products using 3D printers. The 3D printer industry is facing new technical challenges to easily print conductive and non-conductive materials at once. .

Therefore, there is a need for a new 3D printer capable of mixing solid printing materials and liquid printing materials without additional cumbersome processing operations and easily printing conductive and non-conductive materials at once. The present invention relates to this.

Hereinafter, the present invention will be described in more detail with reference to the accompanying drawings.

1 is a block diagram showing the premise of a heterogeneous material fusion 3D printer 100 according to an embodiment of the present invention.

The heterogeneous material fusion 3D printer 100 may include a first output unit 10, a second output unit 20, a third output unit 30, and a controller 40, and other conventional 3D printers. Additional components may also be included. Hereinafter, the first output unit 10 will be described.

The first output unit 10 outputs the first printing material.

Here, the first printing material may be a printing material of a solid material, and there is no limitation on the type of printing material of a solid material, and any of 3D printing printing materials of a known solid material may be used.

Meanwhile, since the first output unit 10 outputs a printing material of a solid material, the first output unit 10 may be viewed as a 3D printer of a conventional FFF or FDM method.

The second output unit 20 outputs the second printing material.

Here, the second printing material may be a printing material of a liquid material, and there is no limitation on the type of printing material of the liquid material, and any of the known liquid material 3D printing printing materials may be used.

On the other hand, since the second output unit 20 outputs the printing material of the liquid material, it may be viewed as a conventional SLA, DLP, Polyjet type 3D printer.

The third output unit 30 outputs any one or more of 3-1 printing material, 3-2 printing material, and 3-3 printing material.

Here, the 3-1 printing material may be a printing material of a solid material, and there is no limitation on the type of the printing material of a solid material, and any of a known 3D printing printing material of a solid material may be used.

More specifically, the 3-1 printing material may be a printing material of a powder material in the printing material of a solid material, and the type of printing material of the powder material is not limited.

Here, although the 3-1 printing material is a printing material of a solid material, the third output unit 30 is implemented in a separate configuration, when the 3-1 printing material is a printing material of a powder material. 1 It must be stored separately from the printing material and handled separately. This will be described in detail in an embodiment to be described later.

On the other hand, the 3-2 printing material may be a printing material of the liquid material, there is no limitation on the type of the printing material of the liquid material, any of the known 3D printing printing material of the liquid material may be used.

Here, as in the case of the 3-1 printing material, although the 3-2 printing material is the printing material of the liquid material, the third output unit 30 is implemented in a separate configuration. This is because the printing material can be mixed with the -1 printing material, so it must be stored separately from the second printing material of the general liquid material and handled separately. This will also be described in detail in an embodiment to be described later.

The controller 40 selectively controls the operations of the first output unit 10 to the third output unit 30.

Here, selectively controlling the operations of the first output unit 10 to the third output unit 30 is an epic of which one of the first output unit 10 to the third output unit 30 should be operated first. This means instantaneous control over whether or not to operate two or more simultaneously. For example, the controller 40 may operate the second output unit 20 after first operating the first output unit 10 according to the printed matter, and after operating the first output unit 10 first, It is also possible to operate the three output unit 30. Furthermore, it is possible to cause the third output unit 30 to output only the 3-1 printing material, to output only the 3-2 printing material, or to print the 3-1 printing material and the 3-2 printing. You can also output the material at the same time. The appearance of the selective control of the controller 40 may vary depending on the printed matter, and the appearance of the selective control of the controller 40 is related to the above-described embodiment of the third output unit 30.

Hereinafter, selective control of the first output unit 10 to the third output unit 30 performed by the control unit 40 according to the printed matter will be described.

First, when the printed material is to output the liquid material after the output of the solid material, for example, the solid material is first outputted and cured so that a part of the interior is empty, and then the liquid material is output to the part of the interior emptied. Hardening is mentioned.

In this case, as shown in FIG. 2, the control unit 40 first operates the first output unit 10 to output the first printing material of the solid material. Here, since the first output unit 10 is a high temperature output unit including a heating nozzle (not shown), the first printing material may be hardened by a heating nozzle (not shown) at the same time that the printing is performed, but printing requires time for curing. In the case of the material, the controller 40 may space the predetermined time after the operation of the first output unit 10 and before the second output unit 20 is operated.

If the operation of the first output unit 10 is finished or the curing of the first printing material is completed, the control unit 40 operates the second output unit 20, as shown in FIG. 3, to print the second material of the liquid material. Output the material. Here, since the second output unit 20 is a low temperature output unit including room temperature, the second printing material may be naturally cured at room temperature after being output. However, similar to the first output unit 10, a separate heating nozzle ( Not shown).

Figure 4 shows the final printout of the liquid material output after the solid material output. Since the printing material of the liquid material is fluid in itself, it can naturally fill a part of the interior emptied in the solid material before curing.

Next, the case where the clay material should be output will be described.

Clay material may be produced by mixing a print material of a solid material and a print material of a liquid material.

In this case, the control unit 40 controls the operation of the third output unit 30, and more specifically, the control unit 40 causes the third output unit 30 to display the 3-1 printing material which is a printing material of a solid material. After outputting first, 3-2 printing material which is a printing material of a liquid material can be output, or 3-1 printing material and 3-2 printing material can be output simultaneously. However, after outputting the 3-2 printing material first, the output of the 3-1 printing material should be refrained. The printing material of the liquid material is fluid, but the printing material of the solid material is not fluid, and the printing of the liquid material is performed. This is because the material flows before the material is mixed with the printing material of the solid material and the printing materials of the two introductions are difficult to mix.

Since the third output unit 30 must output at least one of the 3-1 printing material, which is the printing material of the solid material, and the 3-2 printing material, which is the printing material of the liquid material, a storage unit for storing the third output unit 30 is required. In this case, as shown in FIG. 5, the third output unit 30 stores the 3-1 storage unit 31 storing the 3-1 printing material and the 3-2 storing the 3-2 printing material. It may further include a storage unit (32).

Furthermore, in order to form a clay material, the 3-1 printing material of the solid material and the 3-2 printing material of the liquid material should be mixed. As shown in FIG. 3-1 formed at the bottom of the storage part 31 and formed at the bottom of the 3-1 flow path part 33 and the 3-2 storage part 32 through which the 3-1 printing material flows, It may further include a flowing 3-2 flow path portion 34, in this case by forming the 3-1 flow path portion 33 and the 3-2 flow path portion 34 to be connected to each other 3-1 printing material And the 3-2 printing material can be naturally mixed.

On the other hand, when the third output unit 30 outputs a powder printing material of a solid material, as shown in Figure 6, the 3-1 flow path 33 is formed in a spiral to control the output of the powder printing material And, the 3-2 flow path portion 34 may further include a liquid control valve 35 for adjusting the output of the 3-2 printing material of the liquid material, the liquid control valve 35 is completely closed In this case, the 3-2 printing material is not output.

Furthermore, since the third output unit 30 outputs any one or more of the 3-1 printing material or the 3-2 printing material, only one printing material may be output. The flow path part 33 may further include a separate valve (not shown), such as the liquid control valve 35.

In addition, the clay material produced by mixing the 3-1 printing material, which is the printing material of the solid material, and the 3-2 printing material, which is the printing material of the liquid material, is mixed with the printing material of the liquid material. Although it does not have as much fluidity as a liquid material, clay material is very difficult to fill an interior part left in a solid material like the printing material of the liquid material shown in FIG. 3 and removes air present in the interior part. must do it. In this case, the third output unit 30 may further include a separate pressure providing unit 36 as shown in FIG. 7 to increase the fluidity of the powder printing material of the clay material, more specifically, the solid material.

Next, the case where the powder printing material of a solid material should be output is demonstrated.

The control unit 40 drives either the first output unit 10 or the third output unit 30 for outputting a print material of a solid material, and the following description will drive the third output unit 30. The case will be described based on the case, but it will be described in advance that the same applies to the first output unit 10.

The control unit 40 causes the third output unit 30 to output the 3-1 printing material which is the powder printing material of the solid material, and in the case of the powder printing material, the fluidity mentioned in the description of the clay material in FIG. The problem can happen the same. Furthermore, in the case of outputting only the powder printing material, unlike the clay material, since the printing material of the liquid material is not mixed, it may be considered that there is little fluidity.

This problem can be solved by the third output part 30 further including the pressure providing part 36 described above, and at least two injection parts in a portion where the inner part of the solid material is in contact with the surface. This is illustrated in FIG. 8. Referring to FIG. 8, as the powder printing material is injected into the injection part on the left side, air filled in the internal part emptied into the solid material may naturally escape to the injection part on the right side. The interior part left empty in the resultant solid material can be sufficiently filled with the powder printing material, as is the case when the powder printing material is injected into the right injection part.

On the other hand, the curing of the powder printing material can be solved by adding all of the powder printing material to a part of the interior emptied in the solid material, and then adding a configuration such as electrode welding to two or more injection parts. Accordingly, the + electrode and the-electrode are connected to the injection portion, respectively, and a spark phenomenon may occur so that the powder printing material can be easily cured.

Finally, explain the case where you need to output solid and clay materials.

In this case, the controller 40 operates the first output unit 10 first to output the first printing material of the solid material. Here, since the first output unit 10 is a high temperature output unit including a heating nozzle (not shown) of about 60 ° C. to 400 ° C., the first printing material may be output and simultaneously cured by the heating nozzle (not shown). In the case of a printing material requiring time for curing, the controller 40 may space a predetermined time after the operation of the first output unit 10 and before the third output unit 30 is operated.

If the operation of the first output unit 10 is finished or the curing of the first printing material is completed, the control unit 40 operates the third output unit 30 to output clay material, and the description thereof prevents duplicate description. In order to do this, the description of the case of outputting the clay material will be replaced.

So far, the control unit 40 has described the mode of selectively controlling the first output unit 10 to the third output unit 30 according to the printed matter. However, the application of the present invention is not limited thereto, and in all cases, a printing material of a solid material, a printing material of a liquid material, and a clay material may be added.

On the other hand, the first printing material which is a printing material of a solid material is a printing material of a non-conductive material, and at least one of the 3-1 printing material which is a printing material of a solid material or the 3-2 printing material which is a printing material of a liquid material In the case of the printing material of the conductive powder material, the non-conductive material and the conductive material are inevitably bound to each other, and when the printed material is an electronic-related product, this may have a fatal effect on product performance.

In this case, the heterogeneous material fusion 3D printer 100 according to an embodiment of the present invention may further include a fourth output unit 50 for outputting a fourth printing material, as shown in FIG. 9, The controller 40 first operates the first output unit 10 for outputting the first printing material, and then operates the fourth output unit 50 before operating the third output unit 30, and then prints the fourth print unit. The fatal effect on electronic-related products may be reduced by constructing the material from the first printing material of the non-conductive material and the printing material capable of protecting the conductive material 3-1 printing material or 3-2 printing material.

Furthermore, the controller 40 may automatically recognize a portion where the conductive material and the non-conductive material contact each other, and allow the fourth output unit 50 to output the fourth printing material only to the portion to form a kind of protection area. have.

Meanwhile, as described above, curing of the first printing material of the solid material, the third printing material of the solid material, the second printing material of the liquid material, the third-2 printing material, and the clay material is required. The heterogeneous material fusion-composite 3D printer 100 may further include a fifth output unit 60 for outputting a fifth printing material as shown in FIG. 10, and the control unit 40 outputs each printing material. After the operation, the fifth output unit 60 is operated, and the fifth printing material is hardened by any one or more of the first printing material, the second printing material, the 3-1 printing material, the 3-2 printing material and the clay material. The problem of hardening can also be solved by comprised with the printing material of the gaseous material to accelerate | stimulate. Wherein the fifth printing material is not necessarily a printing material of a gaseous material which promotes curing of at least one of the first printing material, the second printing material, the 3-1 printing material, the 3-2 printing material and the clay material. Regardless, the printing material may be a general gaseous material.
Furthermore, the heterogeneous material fusion-composite 3D printer 100 according to an embodiment of the present invention may be any one of a first printing material, a second printing material, a 3-1 printing material, a 3-2 printing material, and a clay material. In addition to the fifth printing material, which is a printing material of the gaseous material that promotes the above curing, in the curing method, a method of curing quickly and hardly by adding a volatile liquid to volatilization at room temperature, a method of naturally drying and curing moisture at room temperature, and One or more of the methods of performing the output itself at low temperature and hardening at high temperature may be selected and used. This can be seen as a kind of ceramic baking that hardens the output at low temperatures, and may be useful if the printing material is clay. For example, the third output unit 30 outputs any one or more of the 3-1 printing material, the 3-2 printing material, and the 3-3 printing material at low temperature, and outputs any one or more of these at high temperature. It can be cured.

In addition, the heterogeneous material fusion-composite 3D printer 100 according to an embodiment of the present invention is the first printing material, the second printing material, the 3-1 printing material, the 3-2 printing material and the clay material used for outputting the printed material. It is also possible to implement the output of the medical product by using at least one of the 3-3 printing material of the printing material harmless to the human body.

So far, the heterogeneous material fusion-composite 3D printer 100 according to an embodiment of the present invention has been described. According to the present invention, there is no need for a separate cumbersome processing operation required for mixing a solid printing material and a liquid printing material, which is a problem of the conventional 3D printer, and the conductive material and the non-conductive material can be easily printed at a time.

On the other hand, the heterogeneous material fusion-composite 3D printer 100 according to an embodiment of the present invention, as well as the above-described configuration, the first output unit 10 for outputting the first printing material, the 3-1 printing material, the third A third output unit 30 for outputting any one or more of the -2 printing material and the third-3 printing material, and a control unit 40 for selectively controlling operations of the first to third output units, The first printing material is either a printing material of a solid material or a printing material of a liquid material, the third-1 printing material is a printing material of a solid material, and the third-2 printing material is a liquid material. The printing material of the, the third-3 printing material, may be implemented with a printing material of clay material. In this case, of course, all the above descriptions are applied.

In addition, the printout of the heterogeneous material fusion-composite 3D printer 100 according to an embodiment of the present invention may be different according to the information on the printout that the user outputs. It may be input directly or through the printout information input software linked with a separate heterogeneous material fusion 3D printer 100.

Hereinafter, a printout output method of a heterogeneous material fusion-composite 3D printer according to another embodiment of the present invention will be described.

11 is a flowchart illustrating representative steps of a printed matter output method of a heterogeneous material fusion-composite 3D printer according to another embodiment of the present invention.

However, this is only a preferred embodiment for achieving the object of the present invention, of course, some steps may be added or deleted as necessary.

First, the control unit 40 receives information about the printed matter from the user (S110).

Here, the information on the printed matter is a concept that includes all the information required for the output of the printed matter, such as the size of the printed matter, the material, the printing material required for printing, and whether the conductive and non-conductive materials are used. Information about the printed matter may be input to the corresponding software to be interlocked with the heterogeneous material fusion 3D printer 100.

Thereafter, the control unit 40 operates one or more of the first output unit 10 for outputting the first printing material or the second output unit 20 for outputting the second printing material according to the received information on the printed matter. Let (S120).

If any one or more of the first output unit 10 or the second output unit 20 is operated, the control unit 40 may be one of the 3-1 printing material or the 3-2 printing material according to the information on the printed matter received. The third output unit 30 for outputting any one or more is operated (S130), and thus the final printed matter may be output.

The final printed matter output according to the flowchart shown in FIG. 11 is a combination of at least one of a solid material or a liquid material and a solid material, a liquid material, or a mixed clay material. . However, the printed matter output method of the heterogeneous material fusion-composite 3D printer according to another exemplary embodiment of the present invention is not limited to the matters illustrated in FIG. 11, and the first output unit performed by the controller 40 according to the above-described printed matter ( 10) to the third control unit 30 will be considered to include all the matters for the selective control.

In addition, the printout method of the heterogeneous material fusion 3D printer according to another embodiment of the present invention has not been described in detail in order to prevent duplication of description, but all the technical of the heterogeneous material fusion 3D printer according to an embodiment of the present invention The feature can be equally applied. For example, the first printing material may be a printing material of a non-conductive material, and at least one of the 3-1 printing material or the 3-2 printing material may be a printing material of a conductive material, and the fourth output unit 50. In step S125, the fourth printing material may be made of a printing material capable of protecting the 3-1 printing material and the 3-2 printing material from the first printing material.

In addition, there is no need for a separate cumbersome machining operation, which is a problem of the conventional 3D printer, which is required for the mixing of the solid and liquid printing materials, and the effect of easily printing the conductive material and the non-conductive material at once is equally applicable.
