Description

[Technical Field]

[0001] This invention relates to the technical field of 3D printing, and in particular to a color 3D printing technology. [Previous Technology]

[0002] For various industries, product development is often abstract, mostly based on designers' imagination in their minds, and then drawing it out as much as possible through blueprints or computer 3D software. However, whether it is blueprints or computers, what is presented is always abstract and relies on people's understanding and imagination. If you want to turn the design into a physical object, whether it is direct processing or mold making, you will inevitably incur expensive processing and mold making costs, as well as long waiting time. To solve the aforementioned problems, 3D printing technology has become a more common choice. Through the setting of modeling software, and then using a 3D printer to quickly print the shape, it has successfully provided people with a simpler and more affordable method.

[0003] While 3D printing technology can facilitate communication, it is not without its flaws. Currently, most 3D printers can only output a single color. If different colors are needed for different areas, coloring must be done manually or mechanically, adding an extra step that reduces efficiency and increases costs. To address this, manufacturers have developed printers that flexibly utilize internal space and simultaneously input different colored filaments, attempting to streamline the coloring process. However, while this invention solves the coloring problem, it creates other issues. Using different colored filaments simultaneously means people need to own or carry multiple filaments at the same time, which is inconvenient for carrying and storing, and the number of colors that can be displayed is limited by the available filaments. Furthermore, flexibly utilizing the internal space of the printer, perhaps by increasing the number of built-in accessories or expanding the number of inlet ports, will affect the external shape and overall size of the machine, thereby increasing costs and making operation more complicated.

[0004] Therefore, based on the above explanation, relevant businesses need to reconsider how to solve and improve the above problems. As a result, the inventor has devoted a lot of time to studying relevant knowledge, comparing the advantages and disadvantages of various products, conducting research and development on related products, and undergoing many experiments and tests. Finally, an "epoxy resin applied to color 3D technology" was launched to improve the above deficiencies and meet the needs of the public. [Summary of the Invention]

[0005] The main purpose of this invention is to complete the coloring process inside the printer before the product is printed, thereby increasing efficiency and saving production costs; it improves upon the shortcomings of conventional technology, which cannot streamline post-coloring. To achieve the above-mentioned effects and improve upon the shortcomings of conventional technology, this invention provides an epoxy resin application for color 3D technology, comprising the following steps: Material preparation step: preparing a plurality of colorants, each colorant being an epoxy resin of a different color; Feeding step: pouring each colorant into a plurality of color tanks of a printer, the printer having an internal working space connecting each color tank; Setting step: the printer having an internal control unit that controls the opening and closing time of a valve in each color tank, and sets the color distribution position of the finished product made from the colorant, so that the valve in each color tank can match the set color... The color distribution position is opened and closed; mixing step: The working space is equipped with a color mixing tank. The control unit controls the opening and closing of the valves of each color tank according to the required color distribution position of the finished product, thereby controlling the volume and timing of the color material flowing into the mixing tank from each color tank, and loading or mixing any two or more color materials in the mixing tank; shaping and unloading step: The printing machine is equipped with a nozzle. The control unit controls the single color material or the mixture of color materials in the mixing tank in the above mixing step. After being extruded from the nozzle, it is cured by irradiation with an ultraviolet machine on a construction platform.

[0006] Based on the technical features defined above for this invention, its advantages are that by completing the coloring before printing, and combining the coloring and printing processes, the post-coloring process, cost, and time can be omitted. Furthermore, the heating wire step can be omitted by directly using epoxy resin, saving electricity and cost. In addition, by using a color code database to establish various color ratio information, more diverse color presentations are added. Overall, it further improves the cumbersome post-coloring process in the prior art, avoids the additional cost caused by an extra process, and improves the problems of inconvenient carrying and storage and reduced efficiency. It is evident that this invention is indeed practical and progressive, and is worthy of promotion in the industry.

Implementation Method

[0007] To clearly illustrate the above-mentioned objectives and effects achieved by the present invention, the features and effects of the embodiments of the present invention will be described in detail with reference to the accompanying drawings. Referring to Figures 1 to 3, the process flow of the present invention will be described first. An epoxy resin used in color 3D technology includes the following steps: Material preparation step (S01): Prepare a plurality of color materials 2, each color material 2 being an epoxy resin of a different color; Feeding step (S02): Pour each color material 2 into a plurality of color tanks 32 of a printing machine 3. The printing machine 3 has an internal working space 7 connecting each color tank 32; Setting step (S03): The printing machine 7 has an internal control unit 8. The control unit 8 controls the opening and closing time of a valve 321 in each color tank 32, and sets the color distribution position of the finished product made from the color material 2, so that the valve 321 of each color tank 32 can be matched with the set color distribution position. Opening and closing; Mixing step (S04): The working space 7 is equipped with a color mixing tank 33. The control unit 8 controls the opening and closing of the valves 321 of each color tank 32 according to the required color distribution position of the finished product, thereby controlling the volume and timing of the color material 2 in each color tank 32 flowing into the color mixing tank 33, and loading or mixing any two or more color materials 2 in the color mixing tank 33; Shaping and unloading step (S05): The printing machine 3 is equipped with a nozzle 34. The control unit 8 controls the single color material 2 or the mixture of each color material 2 in the color mixing tank 33 in the above-mentioned mixing step (S04) to be extruded from the nozzle 34 and cured by irradiation by an ultraviolet machine 4 on a construction platform 36, as shown in the first and second figures.

[0008] According to the steps defined above for the present invention, firstly, each color pigment 2 of different colors is poured into each color tank 32. After starting the printer 3, the required color and the color distribution position information of the finished product made of the pigment 2 are input to the control unit 8. After the input is completed, the mixing step (S04) is started. The control unit 8 controls the opening and closing time of the valve 321 of each color tank 32 to control the volume and timing of each pigment 2 flowing into the mixing tank 33. The color is adjusted in the mixing tank 33. Then, the single pigment 2 or the mixed pigment 2 is extruded through the nozzle 34 and shaped on the construction platform 36. At the same time, the ultraviolet machine 4 is used to irradiate the pigment 2 so that the molecules inside the pigment 2 are solidified by reaction. This not only directly completes the coloring of the physical object A, but also simplifies the process, reduces one step, and saves manufacturing costs because the heating wire is not used.

[0009] Based on the above description, other technical features of the present invention will be further described below. The printer 3 is further provided with a screen display panel 37, and the screen display panel 37 is electrically connected to the control unit 8. Users can view or check the operation of the printer 3 and the control unit 8 through the screen display panel 37. The screen display panel 37 will also display abnormal components when the printer 3 is operating abnormally, so that users can discover and troubleshoot abnormalities in a timely manner, and avoid damage to the printer 3 or the resulting danger.

[0010] In addition, the printer 3 is further provided with a temperature sensor 35, and the control unit 8 is further built with a cooling module 801. The cooling module 801 is electrically connected to the temperature sensor 35. When the temperature of the working space 7 is too high, the temperature sensor 35 transmits an emergency message to the cooling module 801. After receiving the message, the cooling module 801 will activate a heat sink 38 inside the printer 3 to cool down and achieve a constant temperature. This can prevent the printer 3 from burning out and prevent other derivative dangers.

[0011] Furthermore, in order to provide users with a simpler and more automated setup, the control unit 8 further includes a color code database 802 and a ratio adjustment module 803. The color code database 802 contains multiple color ratio information 8021. The ratio adjustment module 803 reads any color ratio information 8021 from the color code database 802 (as shown by the dotted line in the third figure, which indicates the transmission of any color ratio information 8021 read by the ratio adjustment module 803), and then the control unit 8 integrates the information to further control the opening and closing time and speed of the valve 321 of each color slot 32. This configuration is not only more convenient, but also avoids the mixing of incorrect colors and the printing of failed products due to human error.

[0012] In addition, when copying an existing physical object, there may be unknown color mixing ratios. Therefore, the control unit 8 is further provided with a scanning module 804. The scanning module 804 can scan and identify the color of a physical object A. Through the scanning module 804, the color mixing ratio of the physical object A can be obtained and recorded in the color code database 802 (as shown by the dotted line in the third figure, the scanning module 804 records the information in the color code database 802). This not only expands the information in the color code database 802, but also enables replication in industrial applications, allowing discontinued products to be reproduced.

[0013] In summary, the present invention, "Epoxy Resin Applied to Color 3D Technology", is indeed in full compliance with the needs of industrial development in terms of practicality and cost-effectiveness. Moreover, the disclosed structural creation is an unprecedented innovative structure, so its "novelty" is beyond doubt. Furthermore, the present invention can enhance the efficiency of conventional structures, thus it also has "progressiveness". It fully meets the requirements of the Patent Law of our country for the application of utility model patents. Therefore, a patent application is filed in accordance with the law, and we respectfully request that your office examine it as soon as possible and give it approval.
