In describing the present invention, detailed descriptions of related well-known functions or configurations are omitted in order not to obscure the gist of the present invention.

1 shows the configuration of a customized rehabilitation aid manufacturing device for companion animals using 3D printing technology according to the present invention.

The present invention provides customized rehabilitation aids for companion animals with various body shapes and application areas to improve comfort and usability and to provide a customized rehabilitation aid manufacturing device for companion animals using 3D printing technology that can help rehabilitation of companion animals. and a manufacturing method using the same. The rehabilitation aid manufacturing device 1 includes a support device 100, a scanner 200, a 3D printer 300, and a control device 400.

Figure 2 shows the support device according to the present invention in an exploded perspective view.

Referring to FIG. 2, the support device 100 is coupled with a rotation plate 110 on the upper surface of which a companion animal is positioned and rotated for the scan operation of the scanner 200, and a lower surface of the rotation plate 110, which is coupled to the center. It consists of a fixed plate 120 that rotates the rotating plate 110 and is mounted on the ground.

The rotation plate 110 has a disk shape, and a central shaft 111 protruding in a cylindrical shape is formed at the center of the lower surface, into which the rotation shaft 121 protrudes from the center of the upper surface of the fixed plate 120 is inserted and fixed. When such a central shaft 111, a fitting groove 111a into which the rotary shaft 121 can be inserted is recessed at the center, and a plurality of teeth are formed on the inner surface of the fitting groove 111a and the outer circumferential surface of the rotating shaft 121 to form a rotating shaft. 121 is fitted into the fitting groove 111a, and at the same time, the teeth formed on the outer circumferential surface of the rotating shaft 121 may be engaged with the teeth formed on the inner surface of the fitting groove 111a.

The rotating plate 110 is coupled to the fixed plate 120 and can be rotated according to the rotation of the rotating shaft 121 . Therefore, the body of the companion animal located on the rotation plate 110 can be scanned through the scanner 200 fixed to one side of the fixing plate 120 at the same time as the rotation plate 110 rotates, and the companion animal's body can be scanned. The rehabilitation aid 2 can be 3D printed according to the body of the companion animal through the 3D printer 300.

At this time, as shown in FIG. 2, a fixing table 112 for additionally fixing the body of the companion animal may be additionally formed on the upper surface of the rotating plate 110.

The holder 112 is provided on the upper surface of the rotation plate 110, and when the user scans the body of the companion animal, the user places the companion animal on the rotation plate 110, and then moves the holder 112 upward to obtain the image of the companion animal. It can be extended to the same position as the chin.

Therefore, by resting the chin of the companion animal inside the upper surface of the arc-shaped support 112a formed at the top of the holder 112, the companion animal is located on the upper surface of the rotation plate 110, and then the rotation of the rotation plate 110 and During the scanning process of the scanner 200, it is possible to prevent the companion animal from moving or escaping. At this time, since the scanner 200 scans the holder 112 together with the body of the companion animal, there is a risk that the body of the companion animal cannot be accurately measured. When the scanner 200 scans and generates a scan value, the position and shape of the fixing table 112 is pre-stored in the memory of the controller 400 so that the scan value corresponding to the fixing table 112 is omitted.

In addition, like the holder 112, a fixing means (not shown in the drawing) for fixing the legs of companion animals may be additionally included.

That is, the movement of the companion animal positioned on the support device 100 is minimized by fixing not only the neck of the companion animal but also the legs that have a lot of movement together, thereby obtaining a scan value with improved accuracy.

At this time, in the case of the fixing means, the upper surface is opened so that the lower leg of the companion animal, that is, the leg including the sole of the foot, can be inserted and fixed, so that the leg inlet space can be formed in a cylindrical shape of a certain height, but is not limited thereto.

In the fixed plate 120, the upper end of the rotary shaft 121 protrudes toward the center of the upper surface, and the fitting groove 111a is inserted into the upper end of the protruding rotary shaft 121, so that the rotary plate 110 and the fixed plate 120 are coupled.

The fixed plate 120 is made of a disk shape having the same shape as the rotating plate 110, but has a larger load than the rotating plate 110, so when installed on the ground, it does not move and rotates only the rotating plate 110.

The rotating shaft 121 is provided at the center of the fixing plate 120 , the upper end protrudes from the upper surface of the fixing plate 120 , and the lower end is provided inside the fixing plate 120 . At this time, a motor (not shown in the drawing) for rotating the rotating shaft 121 is built into the fixing plate 120, and the control device 400 can control whether or not the motor is driven and the driving speed, through which the companion animal can After being positioned on the rotation plate 110, the rotation shaft 121 is rotated simultaneously with the operation of the scanner 200 so that the rotation plate 110 can be rotated.

At this time, there is a need to adjust the rotational speed of the rotating shaft 121 according to the weight of the companion animal. For example, if the companion animal is light and rotates at a high speed, there is a risk that the companion animal may leave the upper surface of the rotation plate 110 due to rotational force, and in the case of a heavy large dog, if the rotation speed is relatively slow, the scanner ( 200), there is a concern that the rotation plate 110 rotates slowly compared to the scan speed.

Therefore, a weight sensor (not shown in the drawings) capable of measuring the weight of a companion animal including the rotary plate 110 may be additionally provided at the lower end of the rotating shaft 121 embedded in the fixing plate 120.

The weight sensor primarily measures the weight of the companion animal when the user drives the motor that drives the scanner 200 and the rotation shaft 121 through the control device 400, and accordingly, the judgment module in the control device 400 420 automatically adjusts the rotation speed of the rotation shaft 121 according to the measured weight of the companion animal so that the rotation plate 110 rotates at an appropriate speed.

Therefore, it is possible to prevent the companion animal from leaving the rotating plate 110 due to the rotational force due to the fast rotational speed or the companion animal from being anxious through the weight sensor and the determination module 420 . In addition, on the contrary, it is also possible to prevent an excessively long scan operation time due to an excessively slow speed. In particular, when scanning at a slow speed, it is most preferable to scan quickly with a minimum of time because there is a concern that the companion animal may not be positioned on the rotating plate 110 and easily escape.

3 shows a scanner according to the present invention, and FIG. 4 shows an example of scanning a companion animal through a support device and a scanner according to the present invention.

The scanner 200 protrudes from one side of the fixing plate 120, and the protruding end extends upward to scan the body of the companion animal.

At this time, the scanner 200 has a bar-shaped extension column 202 protruding upward, the length of which can be adjusted in the vertical direction according to the user's intention, and a rotating plate 110 at the top of the extension column 202 is provided. A scan module 201 capable of scanning the companion animal's body is formed on the side of the designated direction.

At this time, the extension column 202 is formed on the horizontal extension column 202a extending or contracting in the horizontal direction from one side of the fixing plate 120 and the protruding end of the horizontal extension column 202a, and the scan module ( 201) may be formed and divided into vertically extending pillars 202b extending or contracting in the vertical direction. The extension column 202 may be extended or reduced in a sliding manner, but is not limited thereto, and may use various types of extension or contraction methods.

Therefore, the user can adjust the position of the scanner 200 according to the body shape of the companion animal by extending or contracting the horizontal extension column 202a and the vertical extension column 202b according to the size and height of the companion animal.

5 shows a 3D printer according to the present invention.

Referring to FIG. 5 , the 3D printer 300 receives a scan value generated by the 3D printer 300 scanning the body of a companion animal through a wired or wireless communication method with the scanner 200, and based on this, the 3D printer 300 scans the companion animal. Rehabilitation aids to assist the body can be ejected. This 3D printer 300 includes a storage tank 310 and a printer device 320.

The storage tank 310 is to store the injection liquid for injection of the rehabilitation aid 2 through the 3D printer 300. At this time, in the present invention, instead of using a single type of injection solution, the rehabilitation aid 2 is injected using a mixed injection solution obtained by mixing two types of injection solution, and each injection solution is stored in an unmixed state. It includes a first storage tank 311 and a second storage tank 312 so as to be.

Conventional rehabilitation aids are manufactured as injection-molded products having a certain strength (hardness) because they support and fix the body of a companion animal. However, since these rehabilitation aids have excessively strong strength, companion animals feel discomfort and a sense of heterogeneity in the process of wearing and moving the rehabilitation aids (2), and try to damage or throw them off by biting the rehabilitation aids (2). There is a risk of taking action. In particular, there is a problem that the companion animal is stressed during the wearing period, while a definite effect can be obtained only when the companion animal wears the rehabilitation aid 2 for a long period of time.

In addition, in the process of scanning and ejecting the rehabilitation aid 2 through the scanner 200 and the 3D printer 300, errors in the scan values make it difficult for the actual companion animal's body shape and the rehabilitation aid 2 to fit. There are cases where it does not correspond. In this case, there is a need to process the injection product into a rehabilitation aid (2) by adjusting it (banding) to fit the body of the companion animal while trimming it. There is a problem that it is difficult to eject the rehabilitation aid 2.

Therefore, in the present invention, the first ejection fluid, which is the main component of the rehabilitation aid device 2 and has a hardness that allows the ejected rehabilitation aid device 2 to constantly support and fix the companion animal's body, is stored. 1 storage tank 311 and a second storage tank 312 storing a second injection liquid that makes the rehabilitation aid 2 have some flexibility so that it has some flexibility are provided, respectively, and the control device 400 Through this, the first injection liquid and the second injection liquid are mixed with a mixing ratio according to the manufacturer's intention to create a mixed liquid capable of ejecting the rehabilitation aid 2.

The first injection solution is ABS (Acrylonitrile-Butadiene-Styrene) injection solution that does not undergo thermal deformation at room temperature and has a certain hardness after injection to protect and support the treated area and surgery area of companion animals. ), or various thermoplastic resins such as nylon, but in the present invention, it is most preferable to use PLA (Poly Lactic Acid).

PLA is an eco-friendly material made from raw materials extracted from corn starch, and it has less shrinkage due to thermal deformation, enabling more precise output than other injection liquids. In particular, harmful substances such as environmental hormones or heavy metals are not detected during the process of injection at high temperatures, and due to the nature of companion animals, the worn rehabilitation aid (2) can be licked or bitten, which has the advantage of being safe for companion animals. In addition, since it can be naturally decomposed upon disposal, it also has an effect of being environmentally friendly.

In addition, it is most preferable to use silicone as the second injection-molded liquid that is mixed with the above-described first injection-molded liquid to have softness.

Silicone has heat resistance, is a non-toxic material, is safer than rubber that can emit environmental hormones, and has flexible properties. Therefore, even the movement of the companion animal is bent only to the extent that the shape of the rehabilitation aid 2 is not affected, so that the feeling of difference felt by the companion animal can be minimized.

In particular, in the case of a conventional 3D printer, it is very difficult to control the hardness of an injection product because it prints an injection product with only one injection solution. It has the effect of being able to adjust the hardness of the rehabilitation aid (2).

In addition, since it is injected with a certain ductility, the manufacturer can adjust the shape by directly bending it to fit the wearing part of the companion animal after injection.

The printer device 320 receives the first and second injection liquids from the storage tank 310, mixes them, and uses the scan value of the scanner 200 and the control value of the control device 400 to rehabilitate the rehabilitation aid device 2. to be ejected (printed).

This printer device 320 is connected to the first and second storage tanks 311 and 312 in the storage tank 310, respectively, and the first and second injection solutions are transferred to the inside, and the first and second injection solutions are mixed and generated inside. A mixing nozzle 321 is formed by spraying the mixed solution at a high temperature to injection-mold the rehabilitation aid device 2 .

The mixing nozzle 321 has one end connected to the first and second storage tanks 311 and 312 and a hose for receiving the built-in injection liquid from the storage tank 310, and the other end connected to the mixed liquid mixed inside the mixing nozzle 321. A nozzle through which this jet is formed is formed.

At this time, a propeller (not shown in the drawing) capable of mixing the first and second injection liquids is built into the inner space of the mixing nozzle 321, and this propeller rotates together with the driving of the printer device 320, and the mixing nozzle ( 321) The first and second injection solutions introduced into the inside are completely mixed, and the first and second injection solutions may be prevented from being layered in the rehabilitation aid 2 ejected later as the mixed solution.

The 3D printer 300 ejects the rehabilitation aid 2 according to the body of the companion animal to be applied according to the scan value of the scanner 200 transmitted to the control device 400 and the control value previously stored in the control device 400. make it possible

6 shows a configuration diagram of a control device according to the present invention, FIG. 7 shows an example of use of the control device according to the present invention, and FIG. 8 is a customized rehabilitation aid for companion animals using 3D printing technology according to the present invention. It shows an example of a rehabilitation aid device injected through the device manufacturing device and a companion animal to which it is applied.

Referring to FIG. 6 , the control device 400 controls driving of the support device 100, the scanner 200, and the 3D printer 300, and may include a memory 410 and a determination module 420. .

The memory 410 pre-stores the mixing ratio of the first and second ejection fluids according to the body of the companion animal to which the rehabilitation aid 2 is to be applied, and through this, the first and second ejection fluids in the storage tank 310 are printed by the printer device ( 320) so that it can be moved to the side.

In addition, the scan value of the fixing table 112 is pre-stored so that the above-described scan value of the fixing table 112 can be excluded from the scan values generated by the scanner 200, and the judgment module 420 scans the fixing table 112. The 3D printer 300 can eject the rehabilitation aid 2 with the scan value of the scanner 200 excluding the value.

The determination module 420 scans the companion animal so that the scanner 200 scans the companion animal, removes the scan value that does not correspond to the companion animal's body, that is, noise, and ejects the scan value according to the companion animal's body. The value is adjusted and converted into a control value of the 3D printer 300, through which the 3D printer 300 can perform injection molding.

In addition, as another embodiment of the 3D printer 300 of the present invention, a control module 430 and a display module 440 that allow the manufacturer to directly control the ejection fluid of the rehabilitation aid 2 when printing the rehabilitation aid 2 may further include.

The control module 430 adjusts the hardness by adjusting the mixture ratio of the injection liquid according to the body position of the companion animal to be directly applied by the manufacturer when printing the rehabilitation aid 2 in the 3D printer 300 with the scan value obtained through the scanner 200. may be ejected differently.

That is, when the rehabilitation aid 2 is applied to the neck or legs, a small amount of the second exudate to have softness is mixed because the supporting force for fixing the skeleton is somewhat required, and the body of the companion animal that affects the movement When the rehabilitation aid 2 to be applied to the part is ejected, a relatively large amount of the second injection solution is provided to the printer device 320 to be mixed with the first injection solution compared to the above-described case.

At this time, as shown in FIG. 7, through the display module 440, the manufacturer can check and select the body part to which the injected rehabilitation aid 2 will be applied, and the mixing ratio corresponding to the part selected by the manufacturer through the display module 440 It is stored in the memory 410 and allows the 3D printer 300 to perform injection molding with a mixed solution in which the first and second injection solutions are mixed according to the mixing ratio previously stored in the memory 410 .

In the present invention, the mixing ratio of the first and second injection solutions was calculated through the following experiment.

First, 12 comparative examples were produced by dividing the mixing ratio of the first injection solution and the second injection solution by 0.5 units. At this time, since it is difficult to manufacture the rehabilitation aid 2 to be obtained in the present invention because it is excessively hard or excessively soft when it is composed of only one of the first or second injection liquid, it was not manufactured as a comparative example in this experiment. In addition, when the mixing ratio of the first and second injection solutions exceeds 4:6, the silicone ratio becomes excessively high and the treated area cannot be protected and supported, so even when the mixing ratio of the second injection solution exceeds 6, Comparative Example did not produce

Therefore, in Comparative Examples 1 to 12 prepared by adjusting the mixing ratio as described above, weights of 5kg and 10kg corresponding to the weights corresponding to small dogs and medium-sized dogs among general companion animals were placed on the upper surface of the comparative examples mounted on the ground. The strain was confirmed in the form of pressing, and the results are shown in Table 1 below.

comparative example	mixing ratio (1st injection solution: 2nd injection solution)	5 kg pressurized	10 kg pressurized
One	9.5:0.5	no deformation	very small deformation
2	9:1	microdeformation	slightly deformed
3	8.5:1.5	microdeformation	slightly deformed
4	8:2	slightly deformed	slightly deformed
5	7.5:2.5	slightly deformed	somewhat deformed
6	7:3	somewhat deformed	transform
7	6.5:3.5	transform	transform
8	6:4	transform	transform
9	5.5:4.5	transform	transform
10	5:5	transform	very deformed
11	4.5:5.5	transform	very deformed
12	4:6	very deformed	very deformed

Therefore, as can be seen from Table 1 above, there is little change in Comparative Example 1, and when the mixing ratio of the first injection solution drops below 7, including Comparative Example 6, the rehabilitation aid 2 is greatly affected by low pressure. It can be seen that it is deformed and it is difficult to protect or support the treatment area or fracture area of the companion animal.

In the present invention, since the rehabilitation aid (2) has some ductility and should not interfere with the activity of the companion animal wearing it, only slight deformation is required even with small or large pressure Comparative Example 1 in which it is greatly deformed or not deformed at all , it can be seen that it is difficult to use in the case of 5 to 12.

Therefore, in the present invention, the mixing ratio of the first and second injection solutions is made within the range of 9:1 to 8:2 (corresponding to Comparative Examples 2 to 4) to protect and support (fix) the worn part, but move It is also finely deformed so that even if the companion animal moves, the rehabilitation aid 2 can be easily worn without a sense of heterogeneity.

At this time, in the present invention, the rehabilitation aid 2 is used by using a mixing ratio of 9:1 with high hardness for the neck or leg, which is a worn part that is not affected by movement and requires strong fixation and support, and affects movement Use a mixing ratio of 8:2, which has a relatively high strain rate, for the part corresponding to the body, which is a part that is slightly affected. The mixing ratio that varies depending on the worn part is pre-stored in the memory 410, and when the manufacturer selects the worn part through the control module 430 and the display module 440, the injection is performed according to the appropriate mixing ratio pre-stored in the memory 410. make it possible

The rehabilitation aid device 2 manufactured through the rehabilitation aid device manufacturing device 1 according to the present invention does not require a separate post-processing process (polishing, etc.), and surface roughness is minimized by mixing the second injection liquid having ductility. can do. In addition, by directly photographing the companion animal's body, that is, the worn part through the scanner 200, and custom-made, micro-unit accuracy can be realized, and the worn part is protected and supported by being flexibly deformed even when the worn companion animal moves. At the same time as (fixation), it does not affect movement, so it can be induced to wear for a long time without any discomfort or discomfort.

A method of manufacturing the rehabilitation aid device 2 through the rehabilitation aid device manufacturing device 1 will be described with reference to FIGS. 9 and 10 .

9 is a flow chart showing a method of manufacturing a customized rehabilitation aid for companion animals using 3D printing technology according to the present invention, and FIG. is indicated by

Referring to FIG. 9, the method of manufacturing the rehabilitation aid 2 according to the present invention includes a mounting step (S10), an input step (S20), a scanning step (S30), a printing step (S40), and a shape control step (S50). can include

The placing step (S10) is a step of placing the companion animal on the upper surface of the rotation plate 110 of the support device 100, and may include a scanner adjustment step (S11) and a holder adjustment step (S12).

The scanner adjustment step (S11) is to adjust the position of the scanner 200 according to the height or size of the companion animal, and the manufacturer adjusts the extension column 202 before performing the scanning step (S30) so that the scanner 200 can be adjusted to the companion animal. This is a step of adjusting so that the rehabilitation aid 2 can be positioned to correspond to the body part to which the rehabilitation aid 2 is to be applied.

The fixing table adjusting step (S12) is a step of fixing the companion animal by adjusting the position of the fixing table 112 so that the companion animal can be maintained in a fixed state on the rotating plate 110.

The input step (S20) is a step in which the manufacturer inputs a control value for the rehabilitation aid device 2 to be printed (injected) to control the driving of the rehabilitation aid device control device 400.

In this input step (S20), the manufacturer inputs a control value through the control device 400 so that the rehabilitation aid manufacturing device 1 can manufacture the rehabilitation aid device 2 that meets the manufacturer's intention.

The scanning step (S30) is a step of scanning the body of the companion animal through the scanner 200, the support device driving step (S31) in which the support device 100 is driven according to the pre-stored set values, and the support device 100 A scanner driving step (S32) of driving the scanner 200 simultaneously with the rotation of the 3D scan of the companion animal's body is included.

As described above, in the support device driving step (S31), the weight of the companion animal mounted on the rotation plate 110 is detected through the weight sensor in the fixed plate 120, and the rotation plate 110 is moved according to the generated detection value. The rotational speed of is automatically set so that the rotating plate 110 and companion animals can rotate accordingly.

The scanner driving step (S32) is started simultaneously with the rotation of the rotation plate 110, and is a step in which the scanner 200 generates a scan value while performing a scanning operation. At this time, noise is automatically removed from the scan value generated in the scanner driving step (S32), and an operation of transmitting the highly accurate scan value to the 3D printer 300 is performed together.

In the printing step (S40), the 3D printer 300 receiving the scan value generated in the scanning step (S30) prints the rehabilitation aid 2 through the control value input in the input step (S20) including the scan value ( injection) step.

In this printing step (S40), the mixing ratio of the ejection fluid of the rehabilitation aid 2 previously stored in the memory 410 in the control device 400 is called according to the control value, and accordingly, the rehabilitation aid in the 3D printer 300 ( 2) can be produced by printing.

The shape control step (S50) is a step of manufacturing the rehabilitation aid device 2 into a finished product before finally wearing it on a companion animal through the printing step (S40). That is, since unnecessary parts of the rehabilitation aid 2 that are printed (injected) according to the scan values can be printed together, only the parts to be used practically are used except for these parts. In addition, the manufacturer can additionally adjust the shape of the rehabilitation aid 2 by manpower so that it can be easily transformed according to the activity of the companion animal rather than the scan value.

This shape control step (S50) includes a cutting step (S51) in which the manufacturer cuts the injection product to fit the wearable part of the companion animal, and the manufacturer directly transforms the cut injection product to fit the radius of motion of the companion animal to adjust the shape. It includes a bending step (S52).

Therefore, through this shape control step (S50), it is possible to manufacture a companion animal-customized rehabilitation aid (2).

As shown in FIG. 8, the rehabilitation aid (2) manufactured by performing the above-described steps is worn and fixed in a form attached to the companion animal's body along with an auxiliary device such as a band to protect the treatment area, fracture area, etc. of the companion animal can be supported and fixed.

Meanwhile, an anti-corrosion coating layer may be applied to the rotating shaft 121 to prevent corrosion.

The coating material of this anti-corrosion coating layer is bisphenol A novolak type glycidyl ether 19% by weight, isopropylamine 18% by weight, hafnium 14% by weight, organic acid magnesium 14% by weight, titanium oxide (TiO ₂ ) 9% by weight, It is composed of 10% by weight of aluminum oxide (Al ₂ O ₃ ) and 16% by weight of a polymer fluorochemical active, and has a coating thickness of 7 μm.

Bisphenol A novolak-type glycidyl ether and isopropylamine serve to prevent corrosion and discoloration, and hafnium is a transition metal element with corrosion resistance and serves to have excellent waterproofness and corrosion resistance.

Organic acid magnesium serves to impart alkali resistance and wettability to the surface of the coating film, polymeric fluorochemical active serves as a surface activity, and titanium oxide and aluminum oxide are added for the purpose of fire resistance and chemical stability.

The reason for limiting the ratio of the components and the coating thickness as described above is that the present inventors have repeatedly failed several times and analyzed the test results, and as a result, the ratio showed the optimal anti-corrosion effect.

In addition, an antifouling coating layer made of an antifouling coating composition may be applied to the support device 100 to effectively prevent adhesion and removal of contaminants.

The antifouling coating composition contains sodium sesquicarbonate and butyl carbitol in a molar ratio of 1:0.01 to 1:2, and the total content of sodium sesquicarbonate and butyl carbitol is 1 to 10% by weight based on the total aqueous solution. .

The molar ratio of the sodium sesquicarbonate and butyl carbitol is preferably 1:0.01 to 1:2. If the molar ratio is out of the above range, the coating property of the support device 100 is reduced or the surface moisture absorption increases after coating Thus, there is a problem in that the coating film is removed.

The sodium sesquicarbonate and butyl carbitol are preferably 1 to 10% by weight of the total aqueous solution of the composition. If the content is less than 1% by weight, the coating property of the support device 100 is reduced, and if it exceeds 10% by weight, the coating Crystallization is likely to occur due to an increase in film thickness.

On the other hand, as a method of applying the antifouling coating composition to the support device 100, it is preferable to apply it by a spray method. In addition, the final coating film thickness of the support device 100 is preferably 700 to 2500 Å, more preferably 900 to 2000 Å. If the thickness of the coating film is less than 700 Å, there is a problem of deterioration in the case of high-temperature heat treatment, and if it exceeds 2500 Å, there is a disadvantage in that crystallization of the coated surface is easy to occur.

In addition, this antifouling coating composition can be prepared by adding 0.1 mole of sodium sesquicarbonate and 0.05 mole of butyl carbitol to 1000 ml of distilled water and then stirring.

The reason why the ratio of the constituent components and the thickness of the coating film were numerically limited as described above was that the present inventors showed the optimal antifouling coating effect at the ratio as a result of analyzing the test results while repeating several failures.

And, a vibration absorption unit may be further installed at the bottom of the 3D printer 300.

The vibration absorbing part may be made of a rubber material, and the raw material content of the vibration absorbing part is 60% by weight of rubber, 8% by weight of dibutylthiourea, 6% by weight of calcium stearate, 19% by weight of carbon black, 3C (N- 3% by weight of PHENYL-N'-ISOPROPYL-P-PHENYLENEDIAMINE) and 4% by weight of organic peroxide were mixed.

Dibutylthiourea is added to improve vulcanization acceleration, calcium stearate is added to act as a softener, and carbon black is added to increase or improve wear resistance, thermal conductivity, and the like.

3C (N-PHENYL-N'-ISOPROPYL-P-PHENYLENEDIAMINE) is added as an antioxidant, and organic peroxide is added to act as an accelerator.

Therefore, in the present invention, since elasticity, toughness, and rigidity of the vibration absorbing part are increased, durability is improved, and thus the life of the vibration absorbing part is increased.

The tensile strength of the rubber material is formed at 155Kg/㎠.

The reason for limiting the components and components of the rubber material and limiting the numerical values of the mixing ratio is that, as a result of the inventor's analysis through test results while repeating several failures, the optimal effect in the constituent components and numerically limited ratios showed up
