Description

Technical Field

[0001] This application belongs to the field of 3D printing technology, specifically relating to a UV full-color 3D printing device. Background Technology

[0002] 3D printing technology, with its unique advantage of rapidly transforming digital three-dimensional models into physical objects, has found increasingly widespread application in numerous industries such as industrial manufacturing, healthcare, creative design, and education and scientific research. Color 3D printing, in particular, has garnered significant attention because it can endow printed three-dimensional models with more realistic, vivid, and diverse appearances, greatly expanding the application scope and visual effects of 3D printed products.

[0003] However, for most existing 3D printers, achieving color printing requires selecting specific colors of filament and placing them into the printer's printing module. This means that multiple colors of filament need to be prepared in advance, and the colors must be switched during printing based on the desired color distribution of the model. This method of color 3D printing has several drawbacks. First, the need to prepare a large quantity of different colors of filament increases material costs, occupies significant storage space, and easily leads to shortages of specific colors, affecting printing flexibility. Second, even with high-precision switching mechanisms and complex control programs, switching between different colors during printing often results in unnatural color transitions, color gaps, or color mixing, especially when printing complex and intricate models, severely impacting print quality and visual effects. Third, the color richness is limited. In reality, people have diverse color needs, and stocking all colors of filament is impractical, making it difficult to accurately reproduce personalized color combinations and limiting creative expression. Fourth, printing efficiency is affected. Each time consumables are switched, time is spent adjusting the printhead and calibrating the colors, which interrupts the printing process, resulting in reduced overall efficiency and extended production cycle. When faced with large-scale or time-sensitive tasks, it is not up to the task. Utility Model Content

[0016] The printing module and the coloring module are configured to perform the first working mode.

[0017] As a further improvement to this application, in the UV full-color 3D printing equipment provided by this application, the first transmission component includes:

[0018] The first support housing is connected to the first lead screw and the second lead screw respectively, and is provided with a first sliding track, and is provided with a first synchronous belt and a second synchronous belt inside.

[0019] The first sliding track is slidably connected to the first sliding seat and the second sliding seat;

[0020] The first synchronous belt is connected to the first motor so that the first sliding seat can be moved by the first motor.

[0021] The second synchronous belt is connected to the second motor so that the second sliding seat can be moved by the second motor.

[0022] As a further improvement of this application, in the UV full-color 3D printing equipment provided by this application, the printing module extrudes consumables along a first path to print the 3D model according to the slice data of the 3D model, and the coloring module sprays coloring ink along a second path opposite to the first path according to the slice data of the 3D model to color the consumables extruded by the printing module.

[0023] As a further improvement to this application, the UV full-color 3D printing equipment provided in this application also includes a second transmission component;

[0024] The second transmission assembly is connected to both the first lead screw and the second lead screw. The printing module and the coloring module are spaced apart by a preset distance and are both connected to the third sliding seat so that they are slidably mounted on the second transmission assembly via the third sliding seat.

[0025] The printing module and the coloring module are configured to perform the second working mode.

[0026] As a further improvement to this application, in the UV full-color 3D printing equipment provided by this application, the second transmission component includes:

[0027] The second support housing is connected to the first lead screw and the second lead screw respectively, and is provided with a second sliding track and a third synchronous belt inside.

[0028] The second sliding track is slidably connected to the third sliding seat;

[0029] The third synchronous belt is connected to the third motor so that the third sliding seat can be moved by the third motor.

[0030] As a further improvement of this application, in the UV full-color 3D printing equipment provided by this application, the height between the coloring nozzle of the coloring module and the heated bed platform is greater than the height between the consumable nozzle of the printing module and the heated bed platform.

[0031] As a further improvement of this application, in the UV full-color 3D printing equipment provided by this application, the coloring module colors the consumables extruded by the printing module by mixing CMYK 4-bit primary color inks;

[0032] Alternatively, the coloring module may color the consumables extruded by the printing module by mixing RGB three-color inks.

[0033] Compared with the prior art, the UV full-color 3D printing equipment provided in this application embodiment is configured with a printing module that extrudes filament according to the slice data of the 3D model to create the 3D model, and a coloring module that sprays coloring ink according to the slice data of the 3D model to color the filament extruded by the printing module. With this configuration, when printing a full-color 3D model, it is no longer necessary to set the color of the filament, thereby avoiding the cost increase caused by switching different color filaments in the printing module. Furthermore, this embodiment configures the printing module and the coloring module to either a first working mode or a second working mode. In the first working mode, the printing module and the coloring module operate alternately. The printing module first creates a 3D model layer by layer based on the slicing data of the 3D model. After the printing module creates one layer of the 3D model, the coloring module applies color to the filament extruded by the printing module layer by layer based on the slicing data of the 3D model. Based on this configuration, this embodiment prints and colors the 3D model layer by layer, improving the coloring accuracy of the 3D model and facilitating timely correction of problems that occur during each layer of printing. In addition, this embodiment achieves independent control of the printing module and the coloring module. The color module reduces the control difficulty of the coordinated operation of the printing module and the coloring module, and improves the reliability of the UV full-color 3D printing equipment. When it is in the second working mode, the printing module and the coloring module operate synchronously, so that the printing module creates the 3D model according to the slicing data of the 3D model, and the coloring module moves with the printing module. After a preset delay, the coloring module synchronously colors the consumables extruded by the printing module according to the slicing data of the 3D model. Based on this configuration, the embodiments of this application control the printing module and the coloring module to operate synchronously, thereby improving the continuity of the 3D model building process, reducing the overall production time, and improving the printing efficiency of the 3D model.

Detailed Implementation

[0044] To make the objectives, technical solutions, and advantages of this application clearer, the application will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are merely illustrative of this application and are not intended to limit this application.

[0045] In the description of this application, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified. All directional indications (such as up, down, left, right, front, back, etc.) in the embodiments of this application are only used to explain the relative positional relationships and movement of the components in a specific posture (as shown in the figures). If the specific posture changes, the directional indication will also change accordingly. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion.

[0046] To make the description of this disclosure more detailed and complete, illustrative descriptions of the implementation methods and specific embodiments of this application are provided below; however, this is not the only form of implementing or utilizing the specific embodiments of this application. The implementation methods cover the features of multiple specific embodiments and the method steps and their order for constructing and operating these specific embodiments. However, other specific embodiments may also be used to achieve the same or equivalent functions and step sequences.

[0047] See Figures 1 to 6 This application provides a UV full-color 3D printing device, including a printing module 100 and a coloring module 200. The printing module 100 is used to extrude consumables according to the slicing data of a 3D model to create a 3D model; the coloring module 200 is used to spray coloring ink according to the slicing data of the 3D model to color the consumables extruded by the printing module 100. The printing module 100 and the coloring module 200 are configured to perform a first working mode or a second working mode: when the printing module 100 and the coloring module 200 are configured to operate in the first working mode, the printing module 100 and the coloring module 200 operate alternately. In this way, the printing module 100 will first create a 3D model layer by layer according to the slicing data of the 3D model, and the coloring module 200 will color the consumables extruded by the printing module 100 layer by layer according to the slicing data of the 3D model after the printing module 100 has created one layer of the 3D model. When the printing module 100 and the coloring module 200 are configured in the second working mode, they will operate synchronously. This means that while the printing module 100 creates the 3D model based on the slice data of the 3D model, the coloring module 200 will move along with the printing module 100 and, after a preset delay, synchronously color the filament extruded by the printing module 100 according to the slice data of the 3D model. Optionally, the printing module 100 extrudes filament to print the 3D model based on the shape information in the slice data of the 3D model, while the coloring module 200 sprays ink to color the printed 3D model based on the color information in the slice data of the 3D model.

[0048] As one implementation method, the UV full-color 3D printing equipment provided in this application embodiment, when the printing module 100 and the coloring module 200 are configured in the first working mode, when the UV full-color 3D printing equipment prints a 3D model, firstly, the 3D model file to be printed and colored (such as a common STL format file) is imported into the UV full-color 3D printing equipment, and then the data processing module built into the equipment performs slicing processing on the 3D model file to generate a series of two-dimensional slice data with a certain thickness. Then, the printing module 100 starts working. According to the first layer of slice data, the printing nozzle of the printing module 100 follows a pre-planned path (this path is based on the shape and structure of the model and to avoid nozzle interference). Factors such as the model shape and structure are generated by an algorithm to gradually outline the shape of the first layer of the 3D model. After the printing module 100 completes the printing of the first layer of the 3D model, the coloring module 200 starts working. Based on the corresponding slice data, the coloring nozzle of the coloring module 200 moves along a pre-planned path (this path is also generated by an algorithm based on the model shape, structure, and to avoid nozzle interference), spraying coloring ink onto the surface of the newly printed layer of filament. During the spraying process, the coloring nozzle automatically adjusts parameters such as spray angle and flow rate according to the shape details of the model to ensure that the ink evenly covers the visible parts of the model layer, avoiding uneven coloring or omissions. At this point, the printing module 100 and the coloring module 200 have completed the printing of the first layer of the 3D model, and continue to print the remaining layers of the 3D model in the same way. For example, when printing an art sculpture model with fine textures, this coloring method in the first working mode can accurately color each layer of texture, giving it a good color effect and sense of layering.

[0049] As another implementation, the UV full-color 3D printing equipment provided in this application embodiment, when the printing module 100 and the coloring module 200 are configured in the second working mode, when the UV full-color 3D printing equipment prints a 3D model, firstly, the 3D model file to be printed and colored (such as a common STL format file) is imported into the UV full-color 3D printing equipment, and then the data processing module built into the equipment performs slicing processing on the 3D model file, generating a series of two-dimensional slice data with a certain thickness. Then, the printing module 100 and the coloring module 200 will start running synchronously to print... The printing module 100 extrudes filament to construct a 3D model based on the slice data. While the print head of the printing module 100 moves along a preset path to extrude the filament, the coloring module 200's coloring nozzle also moves along with it. However, the coloring module 200 delays for a preset time (e.g., 1 second based on actual testing; this preset time should consider factors such as the filament extrusion speed and printing speed of the printing module 100, the ink drying characteristics of the coloring module 200, and the coloring effect) before performing the coloring operation based on the current slice data. This is to ensure that the printing module 100 first extrudes an appropriate amount of filament to form a base surface that facilitates ink adhesion. After a certain delay, the nozzle of the coloring module 200 sprays coloring ink onto the freshly extruded filament, achieving simultaneous coloring. For example, when mass-producing small creative 3D models with a unified color design, this method of printing and simultaneous coloring can efficiently complete the production of each model, ensuring natural color transitions and high overall production efficiency. Similarly, when the printing module 100 and the coloring module 200 are configured in the second working mode, the printing module 100 will also complete the 3D model printing operation before the coloring module 200. Because the printing module 100 and the coloring module 200 operate synchronously, after the printing module 100 completes the 3D model printing operation, it will wait for the coloring module 200 to complete the coloring operation, and then return to its initial position together with the coloring module 200.

[0050] The UV full-color 3D printing equipment provided in this application embodiment is configured with a printing module that extrudes filament according to the slice data of the 3D model to create the 3D model, and a coloring module that sprays coloring ink according to the slice data of the 3D model to color the filament extruded by the printing module. With this configuration, when printing a full-color 3D model, it is no longer necessary to set the color of the filament, thereby avoiding the cost increase caused by switching different color filaments in the printing module.

[0051] Furthermore, in this embodiment, the printing module and the coloring module are configured to either a first working mode or a second working mode. In the first working mode, the printing module and the coloring module operate alternately. The printing module first creates a 3D model layer by layer based on the slicing data of the 3D model. After the printing module creates one layer of the 3D model, the coloring module applies color layer by layer to the filament extruded by the printing module based on the slicing data of the 3D model. By configuring the printing module and the coloring module in the first working mode, this embodiment can flexibly and precisely adjust parameters such as the coloring range, angle, and ink jet volume according to the specific shape, contour, and detail features of each layer, thereby effectively avoiding… This method avoids problems such as uneven coloring, omissions, or unreasonable color coverage that are common in traditional printing and coloring methods. On the other hand, this alternating operation method also allows operators or the equipment's own monitoring system to check the quality of each layer in a timely manner after printing and coloring. Once printing defects (such as interlayer connection problems caused by uneven material extrusion) or coloring defects (such as color deviation, uneven coloring, etc.) are found, adjustments and corrections can be made quickly, avoiding the accumulation of problems until the entire model printing and coloring is completed. This reduces material waste and the possibility of rework, and greatly improves the overall production quality of the final 3D model.

[0052] When in the second working mode, the printing module and the coloring module operate synchronously, so that the printing module creates a 3D model based on the slice data of the 3D model, and the coloring module moves with the printing module. After a predetermined delay, the coloring module synchronously colors the filament extruded by the printing module based on the slice data of the 3D model. By configuring the printing module and the coloring module in the second working mode, this embodiment controls the printing module and the coloring module to operate synchronously, thereby ensuring that the entire printing and coloring process of the 3D model can be carried out continuously, reducing the time loss caused by frequent switching operations in the traditional method, and greatly improving the overall efficiency of printing and coloring.

[0053] It is understood that the UV full-color 3D printing equipment provided in this application aims to provide a printing module and a coloring module with collaborative working capabilities, and to enable the printing module and coloring module to operate in a first working mode or a second working mode. Therefore, this application does not limit the specific structure of the printing module and coloring module, taking into account the diversity of the 3D printing technology field and the personalized needs of different users in various application scenarios. Different printing tasks, different types of consumables, and different coloring materials, among other factors, may prompt users to configure the printing module and coloring module differently according to actual conditions, as long as the corresponding functions can be achieved and the printing and coloring collaborative process in both working modes can be satisfied. For example, for a 3D printing equipment, the printing module typically includes a consumable channel, a heating device, and a printing nozzle. The consumable channel is used to receive the consumables, the heating device is used to melt the consumables, and the printing nozzle is used to eject the melted consumables. A cooling fan can also be added to the printing module to cool it down and prevent it from overheating. For example, the coloring module 200 typically achieves full-color printing by mixing and spraying multiple colors of ink (such as CMKY four-color ink or RGB three-color ink).

[0054] In some embodiments, such as Figures 1 to 6 As shown, the UV full-color 3D printing equipment provided in this application embodiment further includes: a heated bed platform 300, which is arranged opposite to the printing module 100 and the coloring module 200, and is used to move in a two-dimensional plane opposite to the printing module 100 and the coloring module 200, and to move up and down in a direction perpendicular to the two-dimensional plane to achieve position adjustment in three-dimensional space. Optionally, the heated bed platform 300 is used to carry the consumables extruded by the printing module 100, and it is located below the printing module 100 and the coloring module 200, and can move relative to the printing module 100 and the coloring module 200 in three-dimensional space, thereby cooperating with the printing module 100 and the coloring module 200 to jointly realize the construction of the 3D model. Optionally, the heated bed platform 300 moves by receiving the slice data of the 3D model.

[0055] In some embodiments, the heated bed platform 300 is used to move along the X-axis of a two-dimensional plane opposite to the printing module 100 and the coloring module 200.

[0056] In some embodiments, such as Figures 1 to 6As shown, a first lead screw 311 and a second lead screw 312 are provided along the vertical direction of the heated bed platform 300. The first lead screw 311 and the second lead screw 312 are respectively mounted on the first base 321 and the second base 322, and are connected by a synchronous belt 313 to achieve synchronous rotation. The first base 321 and the second base 322 are respectively located on both sides of the heated bed platform 300 and are fixedly connected to the heated bed platform 300. Optionally, the first lead screw 311 and the second lead screw 312 can rise or fall synchronously via the synchronous belt, so that the printing module 100 and the coloring module 200 can move with the first lead screw 311 and the second lead screw 312, realizing the movement of the printing module 100 and the coloring module 200 in one direction (i.e., the Y-axis) in three-dimensional space. It should be clear that... Figure 1 and Figure 5 In the view of the UV full-color 3D printing equipment shown, the first lead screw 311, the second lead screw 312, and the timing belt 313 are housed within the housing and are not shown.

[0057] It is understood that the purpose of the UV full-color 3D printing equipment provided in this application embodiment is to enable the printing module and the coloring module to move in two directions in three-dimensional space. This application embodiment does not impose any restrictions on the design structure and driving method of the heated bed platform 300 and the lead screw assembly (i.e., the first base, the second base, the first lead screw, the second lead screw, and the timing belt). For example, the heated bed platform 300 can be designed with a conveyor belt and motor drive to move along the X-axis. This is because in actual 3D printing applications, different users may choose lead screw assemblies and heated bed platforms with different structures based on factors such as cost, accuracy requirements, and specific printing tasks.

[0058] In some embodiments, such as Figures 1 to 4 As shown, the UV full-color 3D printing equipment provided in this application embodiment further includes a first transmission assembly 410, which is connected to a first lead screw 311 and a second lead screw 312. The printing module 100 and a first sliding seat 510 are connected and slidably mounted on the first transmission assembly 410 via the first sliding seat 510. The coloring module 200 and a second sliding seat 520 are connected and slidably mounted on the first transmission assembly 410 via the second sliding seat 520. The printing module 100 and the coloring module 200 are configured to perform a first working mode. Optionally, in this application embodiment, the first transmission assembly 410 is configured to allow the printing module 100 and the coloring module 200 to move in one direction (i.e., the X-axis) in three-dimensional space. That is, the first transmission assembly 410, the first lead screw 311 and the second lead screw 312 of the heated bed platform 300 enable the printing module 100 and the coloring module 200 to move in three directions in three-dimensional space.

[0059] The UV full-color 3D printing equipment provided in this application embodiment, when the printing module 100 and the coloring module 200 are connected to different sliding seats respectively, the printing module 100 and the coloring module 200 are independent and preferably used to execute the first working mode. Initially, the printing module 100 and the coloring module 200 are located at the two ends of the first transmission component 410 respectively. When printing the 3D model, the first sliding seat 510 carries the printing module 100 to work and prints the 3D model layer by layer according to the slicing data of the 3D model. After each layer of the 3D model is printed, the second sliding seat 520 starts to carry the coloring module 200 to work and applies color layer by layer to the 3D model printed by the printing module 100 according to the slicing data of the 3D model.

[0060] It is understood that the purpose of the first transmission component 410 in the UV full-color 3D printing equipment provided in this application embodiment is to enable the printing module 100 and the coloring module 200 to move in one direction in three-dimensional space. This application embodiment does not impose any restrictions on the design structure and driving method of the first transmission component 410. This is because in actual 3D printing application scenarios, different users may choose different structures of the first transmission component 410 based on various factors such as cost, accuracy requirements, and specific printing tasks.

[0061] In some embodiments, such as Figures 1 to 4 As shown, in the UV full-color 3D printing equipment provided in this application embodiment, the first transmission component 410 includes:

[0062] The first support housing 411 is connected to the first lead screw 311 and the second lead screw 312 respectively. It is provided with a first sliding rail 4101, and a first synchronous belt 4111 and a second synchronous belt 4112 are provided inside it. The first sliding rail 4101 is slidably connected to the first sliding seat 510 and the second sliding seat 520. The first synchronous belt 4111 is connected to the first motor 610 so as to drive the first sliding seat 510 to move through the first motor 610. The second synchronous belt 4112 is connected to the second motor 620 so as to drive the second sliding seat 520 to move through the second motor 620.

[0063] The UV full-color 3D printing equipment provided in this application embodiment drives the first sliding seat 510 and the second sliding seat 520 to move on the first sliding track 4101 via the first synchronous belt 4111 and the second synchronous belt 4112, respectively. This enables the printing module 100 and the coloring module 200 to move on the first sliding track 4101 between the first lead screw 311 and the second lead screw 312. It is understood that setting a dual synchronous belt structure to drive the movement of different sliding components is a common and easily implemented technical means. Furthermore, the purpose of this application embodiment is not to propose a synchronous belt structure. Therefore, the specific structural details of the first synchronous belt 4111 and the second synchronous belt 4112 will not be described here.

[0064] In some embodiments, such as Figures 1 to 4 As shown, in the UV full-color 3D printing equipment provided in this application embodiment, when the printing module 100 and the coloring module 200 are preferably configured in the first working mode, the printing module 100 and the coloring module 200 will be located at both ends of the first transmission component 410 in the reset state. When printing a 3D model, the printing module 100 first extrudes the consumable along the first path (this path is generated by an algorithm based on the shape, structure, and avoidance of nozzle interference, etc.) according to the slice data of the 3D model to print the 3D model layer by layer. Since the coloring module 200 is set opposite to the printing module 100, the coloring module 200 can spray coloring ink along the second path opposite to the first path according to the slice data of the 3D model to color the consumable extruded by the printing module 100. This opposite path setting helps to complete the printing and coloring operations more efficiently and without interference in a limited space. Moreover, compared with obtaining the path of the coloring module 200 through complex calculations, using the second path opposite to the first path is obviously simpler.

[0065] In some embodiments, such as Figures 5 to 6 As shown, the UV full-color 3D printing equipment provided in this embodiment further includes a second transmission component. The second transmission component is connected to the first lead screw 311 and the second lead screw 312 respectively. The printing module 100 and the coloring module 200 are set at a preset distance apart and are both connected to the third sliding seat 530 so that they can be slidably mounted on the second transmission component via the third sliding seat 530. The printing module 100 and the coloring module 200 are configured to perform a second working mode. Optionally, in this embodiment, the second transmission component is set so that the printing module 100 and the coloring module 200 can move in one direction (i.e., the X-axis) in three-dimensional space. That is, the second transmission component, the first lead screw 311 and the second lead screw 312 of the heated bed platform 300 enable the printing module 100 and the coloring module 200 to move in three directions (i.e., X, Y, Z) in three-dimensional space.

[0066] In the UV full-color 3D printing equipment provided in this application embodiment, when the printing module 100 and the coloring module 200 are both connected to the same sliding seat, the printing module 100 and the coloring module 200 will move synchronously with the sliding seat. At this time, the printing module 100 and the coloring module 200 are preferably used to execute the second working mode. Initially, the printing module 100 and the coloring module 200 are respectively located at one end of the second transmission component. When printing the 3D model, the third sliding seat 530 moves synchronously with the printing module 100 and the coloring module 200. The printing module 100 prints the 3D model according to the slice data of the 3D model, and the coloring module 200 simultaneously colors the 3D model according to the slice data of the 3D model.

[0067] It is understood that the purpose of setting the second transmission component in the UV full-color 3D printing equipment provided in this application embodiment is to enable the printing module and the coloring module to move in one direction in three-dimensional space. However, this application embodiment does not impose any restrictions on the design structure and driving method of the second transmission component. This is because in actual 3D printing application scenarios, different users may choose second transmission components with different structures based on various factors such as cost, accuracy requirements, and specific printing tasks.

[0068] In some embodiments, such as Figures 5 to 6 As shown, in the UV full-color 3D printing equipment provided in this application embodiment, the second transmission component includes:

[0069] The second support housing 422 is connected to the first lead screw 311 and the second lead screw 312 respectively. It is provided with a second sliding rail 4202 and a third synchronous belt (not shown) inside it. The second sliding rail is slidably connected to the third sliding seat 530. The third synchronous belt is connected to the third motor 630 so as to drive the third sliding seat 530 to move through the third motor 630.

[0070] The UV full-color 3D printing equipment provided in this application embodiment uses a third synchronous drive to move a third sliding seat on a second sliding track, thereby enabling the printing module and the coloring module to move on the second sliding track between the first lead screw and the second lead screw. It is understood that setting a synchronous belt structure to drive the movement of different sliding components is a common and easily implemented technical means, and the purpose of this application embodiment is not to propose a synchronous belt structure. Therefore, the specific structural details of the third synchronous belt will not be described here.

[0071] In some embodiments, such as Figures 5 to 6As shown, in the UV full-color 3D printing equipment provided in this application embodiment, the height between the coloring nozzle of the coloring module 200 and the heated bed platform 300 is greater than the height between the filament nozzle of the printing module 100 and the heated bed platform 300, thereby avoiding the problem of the coloring module 200 accidentally touching the filament extruded by the printing module 100 when coloring in the second working mode.

[0072] In some embodiments, such as Figures 1 to 6 As shown, in the UV full-color 3D printing equipment provided in this application embodiment, the consumables extruded by the printing module 100 are colored by mixing CMYK (i.e., cyan, magenta, yellow, and black) four-color inks; or the coloring module 200 colors the consumables extruded by the printing module 100 by mixing RGB (i.e., red, green, and blue) three-color inks.

[0073] It should be clarified that the specific structure of the coloring module is not limited in the embodiments of this application. In fact, for those skilled in the art, it is not difficult to construct a coloring module structure that can color the consumables extruded by the printing module 100 by mixing CMYK four-color inks, or can color the consumables extruded by the printing module by mixing RGB three-color inks. It can be achieved by relying on existing conventional technical methods.

[0074] The UV full-color 3D printing equipment provided in this application embodiment, when a first transmission component is set between the first lead screw and the second lead screw, and the printing module and the coloring module are independently set on the first sliding seat and the second sliding seat respectively, the printing module and the coloring module are preferably configured in a first working mode. At this time, this application embodiment can flexibly and accurately adjust the coloring range, angle and ink jetting volume according to the specific shape, contour and detail features of each layer, thereby effectively avoiding problems such as uneven coloring, coloring omissions or unreasonable color coverage that are easy to occur in traditional printing coloring methods. On the other hand, this alternating operation mode also makes it convenient for the operator or the equipment's own monitoring system to check the quality of the layer in a timely manner after each layer is printed and colored. Once printing defects (such as interlayer connection problems caused by unsmooth material extrusion) or coloring defects (such as color deviation, uneven coloring, etc.) are found, adjustments and corrections can be made quickly, avoiding the accumulation of problems until the entire model printing and coloring is completed before they are discovered, thereby reducing material waste and the possibility of repeated work, and greatly improving the overall production quality of the final 3D model.

[0075] When a second transmission component is provided between the first lead screw and the second lead screw, and both the printing module and the coloring module are mounted on the third sliding seat, the printing module and the coloring module are preferably configured in the second working mode. In this embodiment, the printing module and the coloring module are controlled to operate synchronously, thereby ensuring that the printing and coloring process of the entire 3D model can be carried out continuously, reducing the time loss caused by frequent switching operations in the traditional method, and greatly improving the overall efficiency of printing and coloring.

[0076] It is understood that the technical features of the above embodiments can be combined arbitrarily. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0077] The above embodiments are merely exemplary implementations used to illustrate the principles of this application; however, this application is not limited thereto. For those skilled in the art, various modifications and improvements can be made without departing from the spirit and substance of this application, and these modifications and improvements are also considered to be within the scope of protection of this application.
