Description

Technical Field

[0001] This invention relates to the field of printing equipment technology, specifically to a multi-mode printing system capable of supporting multiple printing modes (e.g., 2D printing, 2.5D printing, and 3D printing) and a method for applying the multi-mode printing system. Background Technology

[0002] Current printing equipment can be categorized into three main types based on its function: 2D printing, 2.5D printing, and 3D printing. However, existing printing equipment often exhibits a single-function characteristic. 2D printing equipment focuses solely on outputting two-dimensional graphics and text. 2.5D printing deposits ink of varying thicknesses on flat or curved surfaces to create textures with different height differences, resulting in visual and tactile variations in the overall texture. 3D printing equipment is used to create three-dimensional solids. This functional barrier limits user application: when a real-world scenario involves both 2D graphic output and 3D solid construction, or when a single user needs to produce products with 2D graphics, 2.5D textures, and 3D solids, it is often necessary to purchase and configure two to three separate printing devices, thereby increasing the cost of the required equipment.

[0003] Existing printing equipment has not yet effectively broken through the functional compatibility bottleneck of planar printing, relief printing and 3D printing, making it difficult to achieve flexible switching and collaborative use of the three printing modes on the same device. This forces users to accept the inefficient configuration mode of "one machine for one need", which limits the application potential of printing technology. Summary of the Invention

[0004] This application provides a multi-mode printing system and a method for applying the multi-mode printing system to solve the technical problem that existing printing devices have limited functionality and cannot be compatible with multiple printing modes.

[0005] To achieve the above objectives, the technical solution adopted in this application is as follows:

[0006] A multi-mode printing system is provided, comprising: a printer body including a printhead mounting assembly; a printhead assembly including a printhead; and an ink cartridge assembly for loading a first ink and / or a second ink; wherein the first ink and the second ink are different; the multi-mode printing system is capable of switching between a first printing mode and a second printing mode, wherein in the first printing mode, the ink cartridge assembly supplies the first ink to the printhead mounted to the printhead mounting assembly; and in the second printing mode, the ink cartridge assembly supplies the second ink to the printhead mounted to the printhead mounting assembly, wherein the first ink is capable of performing at least 2D printing or 2.5D printing, and the second ink is capable of performing at least 3D printing.

[0007] In some embodiments, the printhead assembly includes a first printhead and a second printhead; the first printhead is used to execute a first printing mode, and the second printhead is used to execute a second printing mode. Executing different printing modes with different printheads facilitates rapid switching between printing modes, reduces the need for cleaning and other procedures when switching modes by using the same printhead in two different printing modes, and improves printing efficiency.

[0008] In some embodiments, the ink cartridge assembly includes a first ink cartridge and a second ink cartridge; in a first printing mode, the first ink cartridge supplies first ink to the printhead mounted on the printhead mounting assembly; in a second printing mode, the second ink cartridge supplies second ink to the printhead mounted on the printhead mounting assembly. By supplying different inks to different cartridges, the corresponding cartridge can be quickly selected when switching printing modes, reducing the need for cleaning and material replacement when switching modes using the same cartridge in two different printing modes, thus improving printing efficiency.

[0009] In some embodiments, the printhead assembly includes a first printhead and a second printhead; the ink cartridge assembly includes a first ink cartridge and a second ink cartridge; in a first printing mode, the first ink cartridge supplies first ink to the first printhead mounted on the printhead mounting assembly; in a second printing mode, the second ink cartridge supplies second ink to the second printhead mounted on the printhead mounting assembly. By using different printheads to execute different printing modes and different ink cartridges to supply different inks, switching between printing modes can be achieved without cleaning the printheads and ink cartridges, making the operation simple, convenient, and quick.

[0010] In some embodiments, one of the first and second printheads is selectively mounted to the printhead mounting assembly; or both printheads are mounted to the printhead mounting assembly simultaneously. When the printing system has two printheads, both printheads can be mounted to the printhead mounting assembly of the printer body simultaneously for use as needed. Alternatively, after completing one printing mode, the printhead used for printing can be removed, and a printhead for another printing mode can be installed before restarting printing. For example, after completing 2D or 2.5D printing, the printhead used for 2D or 2.5D printing can be removed, and then a printhead used for 3D printing can be installed for 3D printing.

[0011] In some embodiments, one of the first and second ink cartridges is selectively installed in the printer body; or the first and second ink cartridges are installed in the printer body simultaneously. When the printing system has two ink cartridges, both cartridges can be installed in the printer body simultaneously for use as needed, or the ink cartridge supplying ink can be removed after one printing mode is completed, and the ink cartridge supplying ink for another printing mode can be installed before starting printing. For example, after completing 2D printing or 2.5D printing, the ink cartridge supplying ink for 2D printing or 2.5D printing can be removed, and then the ink cartridge supplying ink for 3D printing can be installed to perform 3D printing.

[0012] In some embodiments, the printhead assembly includes only one printhead, and the system further includes a first cleaning component for cleaning the printhead when switching from a first printing mode to a second printing mode or vice versa; and / or The ink cartridge assembly includes only one ink cartridge.

When the printing system has only one printhead and / or one ink cartridge, cleaning of the printhead and / or ink cartridge is required before switching printing modes. The first and second cleaning components may be the same or different. By performing different printing modes with a single printhead and / or ink cartridge, the system can reduce hardware configuration and lower costs.

[0051] The present invention will now be described in further detail with reference to specific embodiments and accompanying drawings.

[0052] like Figure 1 As shown in Figure 2, this embodiment of the invention provides a multi-mode printing system 100. The system 100 includes a printer body 110, a printhead assembly 120, and an ink cartridge assembly 130. The printhead assembly 120 includes a printhead mounted on a printhead mounting assembly 111 of the printer body 110; the ink cartridge assembly 130 is also mounted on the printer body 110. The ink cartridge assembly 130 contains a first ink and / or a second ink; the first ink and the second ink are different; this multi-mode printing system can switch between a first printing mode and a second printing mode. In the first printing mode, the ink cartridge assembly 130 supplies the first ink to the printhead mounted on the printhead mounting assembly; in the second printing mode, the ink cartridge assembly supplies the second ink to the printhead mounted on the printhead mounting assembly, wherein the first ink can be used for at least 2D printing or 2.5D printing, and the second ink can be used for at least 3D printing. The nozzle assembly 120 of this invention can perform jetting operations based on received control data, thereby achieving three different output forms on a single device: conventional two-dimensional (2D) printed images, three-dimensional relief texture structures with finite and variable height (also known as 2.5D printing), and three-dimensional (3D) solid objects with arbitrary shapes. The core technological advantage of this printing system 100 lies in breaking down the functional barriers of traditional printing equipment through an integrated hardware platform and intelligent control logic. This allows users to flexibly select output modes according to their needs without having to purchase 2D, 2.5D, and 3D printers separately, significantly reducing equipment purchase costs, saving workspace, and greatly improving ease of use and overall efficiency.

[0053] The cartridge assembly 130 is used to hold a first ink and / or a second ink; the first and second inks differ in physical properties (such as viscosity) or chemical composition to accommodate different printing modes. For example, the first ink can be used for 2D printing (e.g., printing graphics on a flat or uneven medium), and the second ink for 3D printing (e.g., printing three-dimensional solids through layer-by-layer curing); or the first ink can be used for 2.5D printing (e.g., printing textures or reliefs with a certain height on a flat or uneven medium), and the second ink for 3D printing; or the first ink can be used for 2D printing, and the second ink for 2.5D printing. This ink separation design allows the system to provide optimized material for each specific printing task, thereby ensuring the final print quality, whether in terms of color reproduction, texture detail, or structural strength.

[0054] The printer body 110 includes a printhead mounting assembly 111 for supporting and securing the printhead assembly 120. The printhead mounting assembly 111 not only provides a mechanical fixing module for precise positioning and stable motion guidance, but also provides an electrical interface for electrically connecting different printheads, ensuring the positional accuracy of the printheads and the reliability of signal transmission during operation, thus laying the foundation for high-quality printing.

[0055] The aforementioned multi-mode printing system 100 has the ability to switch between a first printing mode (such as 2D printing or 2.5D printing) and a second printing mode (such as 3D printing). In the first printing mode, the ink cartridge assembly 130 supplies first ink to the print head mounted on the print head assembly 111 to form a 2D image or a 2.5D relief structure; in the second printing mode, the ink cartridge assembly 130 supplies second ink to the print head mounted on the print head assembly 111 to build a complete 3D solid. By supplying ink with matching characteristics to the print head assembly (or print head) in different modes, the system can intelligently select the most suitable mode and consumable combination according to the final printing effect and process requirements. This not only realizes a comprehensive manufacturing capability from planar graphics and surface textures to solid models, but also effectively improves equipment utilization and workflow continuity through rapid switching between modes.

[0056] In some embodiments, the multi-mode printing system can switch between different printing modes based on the replacement of different ink cartridges.

[0057] like Figure 1 As shown, this embodiment provides a specific multi-mode printing system 100, the core of which is to achieve ink supply switching between different printing modes by physically replacing ink cartridges loaded with different inks. The structure is intuitive and the operation is reliable.

[0058] In this embodiment, as shown in FIG2(b), the ink cartridge assembly 130 includes a first ink cartridge 131 and a second ink cartridge 132; in a first printing mode, the first ink cartridge 131 supplies first ink to the print head mounted on the print head mounting assembly 111; in a second printing mode, the second ink cartridge supplies second ink to the print head mounted on the print head mounting assembly 111.

[0059] Specifically, the ink cartridge assembly 130 includes separate first ink cartridge 131 and second ink cartridge 132. The first ink cartridge 131 is used for first ink in 2D or 2.5D printing, such as at least two of the following inks: cyan (C), magenta (M), yellow (Y), black (K), white (W), or transparent (T); the second ink cartridge 132 is used for second ink in 3D printing, such as at least two of the following inks: cyan (C), magenta (M), yellow (Y), black (K), white (W), transparent (T), or support material (S), which can be formed into a three-dimensional solid by layer-by-layer curing and stacking. The first ink cartridge 131 and the second ink cartridge 132 can have identical external shape, dimensions, and interface structure, and therefore can be selectively installed into ink cartridge mounting slots on the printer body 110. The ink cartridges (131, 132) are connected to the printhead assembly (121, 122) via ink tube 181 (also referred to herein as the first ink tube or the second ink tube) with a connecting component connector, enabling rapid switching of the sealed flow path. The standardized ink cartridges and cartridge installation bay design eliminate the need for complex adjustments during mode switching, achieving true "plug and play," improving switching efficiency and reducing the risk of ink leakage.

[0060] In this embodiment, the printhead assembly 120 includes a universal printhead. The internal flow channel and nozzle design of this printhead enable it to be compatible with and effectively eject both first and second inks. Different printing modes can be achieved simply by replacing the ink cartridges, avoiding the cost of configuring a dedicated printhead for each ink and improving the versatility of the core component.

[0061] To achieve intelligent management, such as Figure 3 As shown, the multi-mode printing system 100 also includes a control device 150 and a type identification device 160, which are communicatively connected. The type identification device 160 includes an electronic tag reader or physical switch disposed in the ink cartridge installation compartment 112. Figure 6As shown, each ink cartridge (131, 132) is equipped with an identification element 1303 (such as an RFID tag, QR code, barcode, or a specific shaped antenna). When an ink cartridge (131, 132) is installed in the ink cartridge installation slot 112, the type identification device 160 automatically reads its identification element 1303 and sends the information to the control device 150. Based on this, the control device 150 determines whether the currently installed ink cartridge is the first ink cartridge 131 or the second ink cartridge 132, and loads the corresponding print driver, color management, or material parameter package accordingly. This automatic identification function eliminates the tedious steps of manual configuration by the user, effectively preventing printing failures or equipment damage caused by incorrect mode settings, and improving the system's security and automation level.

[0062] The workflow and method of the above embodiments are as follows: S1: Initial Configuration and Mode Selection: The user, according to their needs (e.g., 2D printing), installs the first ink cartridge 131 into the ink cartridge mounting slot 112 of the printer body 110, and installs the print head 120 into the print head mounting assembly 111. Ink tube 181 connects the first ink cartridge 131 and the print head 120. The type recognition device 160 recognizes the first ink cartridge 131, and the control device 150 automatically loads the 2D printing driver and related color management data package.

[0063] S2: First printing mode (such as 2D printing or 2.5D printing) execution: Control device 150 controls the pump and other fluid mechanisms to supply the first ink from the first ink cartridge 131 through the ink tube 181 to the print head to execute the printing task.

[0064] S3: Printing Mode Switching: When it is necessary to switch to 3D printing mode: S31: Cleaning: Automatically start the cleaning program to clean the first ink residue in the print head 120 and ink tube 181.

[0065] S32: Replace ink cartridge: The user disconnects the quick-release connector, removes the first ink cartridge 131 from the ink cartridge installation slot, then installs the second ink cartridge 132 into the same ink cartridge installation slot and connects the ink tube 181.

[0066] S33: System reconfiguration: When the type identification device 160 identifies the second ink cartridge 132, the control device 150 automatically unloads the 2D printing or 2.5D printing parameter data package and loads the 3D printing slicing software interface and modeling material parameter package.

[0067] S4: Second printing mode (3D printing) execution: The control device 150 controls the supply of second ink from the second ink cartridge 132 to the print head to start the 3D printing task.

[0068] In some embodiments, the printer body 110 is provided with two independent ink cartridge installation slots, with the first ink cartridge 131 and the second ink cartridge 132 each installed in one ink cartridge installation slot for simultaneous installation on the printer body. When switching printing modes, only the print head and ink tube 1 need to be cleaned, and then the ink tube 1 can be disconnected from the quick-release interface of the first ink cartridge and connected to the interface of the second ink cartridge. This configuration eliminates the need for physical ink cartridge replacement, further accelerating mode switching. The dual-slot structure can accommodate two types of ink cartridges simultaneously during system operation, facilitating rapid switching between the first and second printing modes without ink cartridge replacement, thereby shortening preparation time for mode switching and reducing the risk of seal failure or contamination due to frequent disassembly and assembly.

[0069] In some embodiments, a multi-mode printing system can switch between different printing modes based on ink replacement.

[0070] In this embodiment, the ink cartridge assembly 130 is a single universal ink cartridge, rather than two dedicated ink cartridges, and the printhead assembly is a universal printhead. Printing mode switching is achieved by replacing the ink within this universal ink cartridge.

[0071] This design allows users to reuse the same ink cartridge hardware and printhead; simply cleaning and refilling with new ink helps reduce the long-term cost of consumable containers. When switching modes, the ink cartridge, printhead, and ink tube must be cleaned, and then another ink cartridge must be refilled. Specifically, when switching from the first printing mode to the second printing mode or vice versa, the printhead, ink cartridge, and ink tube must be cleaned separately, and the ink required for the corresponding printing mode must be filled into the cleaned cartridge before the corresponding printing mode can be executed.

[0072] In some embodiments, the ink cartridge assembly is a universal ink cartridge, and the printhead assembly includes a first printhead 121 and a second printhead 122, both of which are mounted on the printhead mounting assembly 111. When switching printing modes, the ink cartridge assembly 130 is cleaned, and then the ink tube 181 connected to the first printhead 121 is removed from the ink cartridge assembly 130. Then, the other ink tube 181 connected to the second printhead 122 is inserted into the ink cartridge assembly 130. This method enables rapid printhead switching, avoids printhead cleaning, and is particularly suitable for scenarios with extremely high requirements for printing accuracy and ink purity.

[0073] In some embodiments, the ink cartridge assembly is a universal ink cartridge, and the printhead assembly includes a first printhead 121 and a second printhead 122, which are selectively installed to the printhead mounting assembly. When switching printing modes, the ink cartridge assembly 130 is cleaned, the printhead is then replaced, and the ink cartridge assembly and the replaced printhead are reconnected via ink tube 181. This method has relatively low hardware costs, and superior printing performance can be achieved by replacing the printhead with a dedicated one.

[0074] In some embodiments, a multi-mode printing system can achieve switching between different printing modes by replacing both the printhead and the ink cartridge.

[0075] In this embodiment, the printhead assembly 120 includes a first printhead 121 and a second printhead 122 for different printing modes, and the ink cartridge assembly 130 also includes a corresponding first ink cartridge 131 and a second ink cartridge 132. The printhead mounting assembly 111 can be designed to provide two independent mounting positions for simultaneously mounting two printheads, or to provide one mounting position for selectively mounting either the first printhead or the second printhead.

[0076] In this configuration, printing mode switching can be achieved in any of the following ways: Method 1 (Physical Replacement): The user manually replaces the ink cartridge and the corresponding printhead. For example, using the first ink cartridge 131 and the first printhead 121 for 2D or 2.5D printing; when switching, replacing it with the second ink cartridge 132 and the second printhead 122 for 3D printing. This method ensures optimal matching between the printhead and ink, maximizing printing performance in each mode, while reducing the number of hardware components simultaneously connected to the printer body, lightening the burden on the printer body and improving the stability of the printhead movement frame (the printhead mounting assembly is installed on the printhead movement frame; due to the weight of the printhead, installing two printheads simultaneously would affect the stability and high-precision movement of the printhead movement frame).

[0077] Method 2 (Electrically Controlled Switching): The first ink cartridge 131 is connected to the first printhead 121 via an ink tube 181, and the second ink cartridge 132 is connected to the second printhead 122 via another ink tube 181. Two independent printhead-ink cartridge systems are pre-installed on the printer body. An ink tube 181 may be equipped with a solenoid valve. When switching modes is required, the user selects the mode through the software interface, and the control device 150 automatically activates the solenoid valve and printhead power supply of the corresponding system, while simultaneously shutting down the other system. This method achieves "one-click switching," requiring no manual hardware operation, providing the fastest switching speed, the best user experience, and truly realizing seamless integration of multiple modes and efficient production.

[0078] In some embodiments, when the first ink cartridge 131 and the second ink cartridge 132 are installed simultaneously, or when the first print head 121 and the second print head 122 are installed simultaneously, the first ink cartridge 131 and the first print head 121, as well as the second ink cartridge 132 and the second print head 122, can be connected to two ink tubes 181 respectively, and the different ink supplies can be switched electronically.

[0079] In some embodiments, when a universal printhead is installed along with both the first ink cartridge and the second ink cartridge, the first ink cartridge 131 and the printhead 120 can be connected via an ink tube 181, and the second ink cartridge 132 and the printhead 120 can be connected via another ink tube 181. The ink tube 181 may be equipped with a solenoid valve. During mode switching, the original ink cartridge, ink tube 1, and printhead are cleaned. Then, the user selects a mode via a software interface, and the control device 150 controls the corresponding solenoid valve to open, allowing the other ink cartridge to supply ink to the printhead.

[0080] In some embodiments, to improve printing continuity, such as Figure 1 As shown, the printing system also includes a refill assembly 140, which can selectively communicate with the ink cartridge assembly 130 (including the first ink cartridge 131 and / or the second ink cartridge 132) via an ink tube 182 (also referred to herein as the third ink tube) to supply ink to the ink cartridge assembly 130. The refill assembly can adjust the ink supply flow rate and start / stop timing according to the current printing mode and the ink level in the ink cartridge, thereby achieving on-demand ink replenishment to the ink cartridge.

[0081] When the multi-mode printing system 100 is in the first printing mode, the ink supply component can selectively connect to the first ink cartridge 131 to provide replenishing ink, thus meeting the stability requirements of ink supply during 2D or 2.5D printing. However, when the system switches to the second printing mode, because the material consumption rate during 3D printing is significantly higher than that of 2D and 2.5D printing, the ink level in the second ink cartridge 132 is prone to dropping to the lower operating limit during continuous operation. Relying solely on its internal capacity is insufficient to sustain continuous molding for extended periods. Therefore, in the second printing mode, the ink supply component establishes a connection with the second ink cartridge 132 to provide auxiliary ink supply, delivering ink into the second ink cartridge 132 to compensate for ink consumption caused by high-speed lamination.

[0082] The aforementioned ink supply method maintains the ink level within the cartridge assembly 130 within the set working range, preventing issues such as printhead dry running, printing interruptions, or poor interlayer bonding caused by ink depletion. This also reduces the number of job interruptions due to mid-process stoppages for cartridge replacement or manual ink refilling. By introducing a coordinated ink supply mechanism between the refill assembly 140 and the cartridge assembly 130, the solution of this application effectively extends the continuous printing time per cycle, reduces the frequency of manual intervention, and improves overall printing efficiency while maintaining print quality. This enhances the applicability and stability of the multi-mode printing system in actual production scenarios.

[0083] like Figure 4 As shown, in some embodiments, each ink cartridge includes at least two receiving units (a first receiving unit 1301 and a second receiving unit 1302), each receiving unit containing an ink of a specific property. For example, the first receiving unit contains one color ink (such as yellow (Y) ink), and the second receiving unit contains another color ink (such as black (K) ink). The different properties referred to herein may include differences in ink color, viscosity range, curing method, or substrate compatibility, etc., to support multi-color output, functional layering, or specific process effects in the same printing mode. These receiving units are structurally independent of other ink receiving units and have dedicated interfaces and supply channels to supply the corresponding ink to the printhead or ink supply lines when needed. For example, in 2.5D or 2D printing applications, multiple receiving units can be used to load inks of different colors to achieve color graphic output. In 3D printing applications, inks with different properties can be used to undertake the tasks of supporting structure forming and main structure forming, for example, by combining easily removable support materials with high-strength main materials, thereby improving the shape accuracy of the formed parts and simplifying post-processing procedures.

[0084] Specifically, the ink cartridge may include seven housing units for holding cyan ink (C), magenta ink (M), yellow ink (Y), black ink (K), white ink (W), varnish (G), or transparent ink (T), respectively. The G housing unit is used to hold varnish to increase surface transparency, and the T housing unit is used to hold transparent ink that participates in the construction of solid or three-dimensional structures.

[0085] As shown in Figures 5-6, the ink filling assembly 140 includes at least two storage containers (a first storage container 1421 and a second storage container 1422), which are used to hold ink corresponding to at least two receiving units of the ink cartridge assembly 130. The number of storage containers matches the configuration of the ink cartridge receiving units, and the properties of the ink they contain are consistent with the design purpose of the corresponding receiving unit. This allows the ink of specified properties to be quantitatively delivered to the target receiving unit via the pumping and control unit of the ink filling assembly when ink replenishment is needed. The ink filling assembly and each receiving unit can be connected via independent ink supply lines. Each line is equipped with a controllable valve or switching valve. The control device opens the ink supply channel corresponding to the target receiving unit based on the ink cartridge configuration information fed back by the type identification device and the current operating mode, achieving precise ink replenishment and preventing ink mixing.

[0086] During system operation, when the ink level in a certain ink-containing unit falls below a preset threshold, the control device can activate the ink-filling assembly to replenish the ink in that unit based on the ink properties corresponding to that unit and the inventory status of the storage container. This prevents the continuity or quality of printing operations from being affected by the depletion of ink of a single property. With a multi-ink-containing unit structure, the ink-filling assembly can also manage and replenish inks of different properties separately, reducing frequent manual ink changes caused by multi-color or multi-function printing and lowering the risk of accidental mixing of different inks in the ink supply system. By introducing corresponding configurations of multiple ink-containing units and multiple storage containers into the ink cartridges and ink-filling assembly, the solution of this application can expand the color and function combinations achievable in a single print while maintaining a compact hardware structure, improving the adaptability and operational efficiency of the multi-mode printing system in complex process tasks.

[0087] In some embodiments, such as Figure 7 As shown, the multi-mode printing system 100 is also equipped with a first cleaning component 171. When the multi-mode printing system includes only one printhead and / or one ink cartridge to perform printing, the first cleaning component 171 is used to clean the printhead when switching between the first printing mode and the second printing mode, so as to avoid the inks used in different printing modes from contaminating each other or clogging the nozzles.

[0088] The multi-mode printing system is also equipped with a second cleaning component 172, which is used to clean the internal flow channels and ink storage chamber of the ink cartridge when switching between the first printing mode and the second printing mode.

[0089] like Figure 7As shown, the first cleaning assembly 171 mainly includes a cleaning fluid storage unit 1711 and a fluid supply pump 1712. The inlet of the fluid supply pump 1712 is connected to the outlet of the cleaning fluid supply unit 1711 through a cleaning fluid pipeline, and the outlet of the fluid supply pump 1712 is connected to multiple nozzles arranged in an array on the print head 120.

[0090] The cleaning process is as follows: When the control device 150 initiates the cleaning program according to preset conditions (such as detecting a printing mode switch) or according to an instruction, it starts the liquid supply pump 1712, pumping the cleaning liquid in the cleaning liquid receiving unit 1711 to all nozzles of the printhead. The cleaning liquid is sprayed from all or more designated nozzles under a certain pressure, thereby flushing the nozzles. This cleaning step effectively removes residual ink from the nozzles, preventing coagulation, clogging, or chemical reactions caused by mixing inks of different properties, and preventing cross-contamination between inks suitable for different printing modes. This ensures the long-term reliability of the printhead and the quality of printed products in different modes.

[0091] like Figure 4 As shown, the second cleaning assembly 172 is the same as the first cleaning assembly 171, mainly including a cleaning fluid storage unit 1721 and a fluid supply pump 1722. The inlet end of the fluid supply pump is connected to the outlet of the cleaning fluid supply unit 1721 through a cleaning fluid pipeline, and its outlet end is connected to multiple receiving units of the ink cartridge.

[0092] The cleaning process is as follows: When the control device 150 starts the cleaning program according to preset conditions (such as detecting a printing mode switch) or according to an instruction, it starts the liquid supply pump to pump out the cleaning liquid from the cleaning liquid receiving unit. The cleaning liquid is delivered to all receiving units of the ink cartridge through the cleaning liquid pipeline, and flows out from all or more designated receiving units under a certain pressure or under the action of gravity, thereby flushing the receiving units and rinsing the ink in the receiving units clean.

[0093] During the workflow mode switching, the printhead and ink tube are cleaned by the first cleaning component, and the ink cartridge assembly is cleaned by the second cleaning component.

[0094] In some embodiments, the first cleaning assembly and the second cleaning assembly are configured as a single cleaning assembly, providing cleaning for both the cartridge assembly and the printhead assembly. In this embodiment, the cleaning fluid storage unit is integrated both inside the cartridge assembly 130 (i.e., a dedicated storage unit for holding cleaning fluid is provided within the structure serving as either the first cartridge 131 or the second cartridge 132, allowing cleaning fluid to be drawn directly from inside the cartridge when needed) and inside the refill assembly (i.e., a separate storage container is provided in the refill box to hold spare cleaning fluid for replenishment when the cleaning fluid in the storage unit is depleted). The inlet of the supply pump is connected to the outlet of the cleaning fluid storage unit via a pipeline, and the outlet is connected to the common port of the fluid switching valve. The fluid switching valve preferably employs a multi-port solenoid valve structure, with at least a first output port and a second output port. The first output port is connected to multiple nozzles arranged in an array at the bottom of the printhead via a printhead cleaning pipeline; the second output port is connected to the cartridge via a cartridge cleaning pipeline, which branches further after entering the cartridge to connect to individual storage units inside the cartridge.

[0095] When the control device initiates the printhead cleaning program based on preset conditions (such as detecting a print mode switching command) or upon receiving a cleaning command from the user, the control device controls the fluid switching valve to connect its common port to the first output port. Subsequently, the liquid supply pump is activated, pumping the cleaning fluid from the cleaning fluid storage unit to the printhead cleaning pipeline and into the nozzles of the printhead. Under a certain fluid pressure, the cleaning fluid is ejected from all or some designated nozzles, flushing the nozzle surface and internal flow channels to remove residual ink, dissolve dried ink, or impurities. When a cartridge cleaning program is required, the control device controls the fluid switching valve to switch to the second output port. The liquid supply pump pumps the cleaning fluid into the cartridge cleaning pipeline and distributes it to each independent receiving unit of the cartridge, circulating and flushing the ink storage chamber and internal flow channels to remove residual ink. The system can also run a combined cleaning program, controlling the switching sequence of the fluid switching valve to allow the cleaning fluid to act alternately or sequentially on the printhead and cartridge, thereby systematically cleaning the entire ink path from source to end.

[0096] In other embodiments of this application, the fluid switching valve can be composed of multiple independent solenoid valves connected in parallel. For example, a first solenoid valve is used to control the cleaning fluid passage to the printhead, and a second solenoid valve is used to control the cleaning fluid passage to the ink cartridge. By controlling the opening and closing states of the two solenoid valves separately, the same selective cleaning function as the multi-way solenoid valve described above can be achieved, and the control logic is more direct and flexible. In addition, the cleaning assembly can also be equipped with a humectant storage unit to fill the printhead common chamber with humectant after the printhead cleaning is completed, thereby reducing the risk of nozzle drying and clogging.

[0097] In some embodiments, such as Figure 4 As shown, the ink cartridge assembly 130 includes a first liquid level sensor 1304, which is used to detect the liquid level position in the ink cartridge assembly. This first liquid level sensor is used to detect the liquid level position within the corresponding ink cartridge. The purpose of the first liquid level sensor is to obtain real-time information on the amount of ink or other working fluid inside the ink cartridge, providing a basis for ink supply control, mode switching, and refilling operations of the system. The first liquid level sensor can be implemented based on contact or non-contact measurement principles, such as using a float sensor, photoelectric sensor, capacitive sensor, or ultrasonic sensor. Its installation position and detection range are determined according to the internal spatial layout of the ink cartridge and the liquid level change range, ensuring accurate reflection of the liquid level change trend during ink consumption.

[0098] During system operation, the first liquid level sensor converts the detected liquid level signal into an electrical or digital signal and transmits it to the control device. The control device uses this signal to determine whether the liquid level in the ink cartridge is within the normal operating range, and triggers corresponding prompts or control actions when the liquid level approaches or falls below a preset lower threshold. For example, in the first printing mode, when the first liquid level sensor of the first ink cartridge 131 detects that the liquid level has dropped to the lower limit, the control component can pause the operation of the first print head 121, prompting the user to add ink or activate the ink filling component 140 to replenish ink to the first ink cartridge 131; in the second printing mode, when the first liquid level sensor of the second ink cartridge 132 detects insufficient liquid, the control component can automatically activate auxiliary ink supply to maintain the continuity of the 3D printing process based on the operating status of the ink filling component 140 and the ink level in the storage container.

[0099] For ink cartridges with multiple receiving units, a first liquid level sensor can be installed in each receiving unit to independently monitor the liquid level of inks, cleaning agents, or humectants with different properties. This allows the control component to perform itemized replenishment and targeted maintenance based on the liquid level of each receiving unit. The first liquid level sensor can also work in conjunction with a type identification component, transmitting the liquid level status of the currently installed ink cartridge and the cartridge type information to the control device during system initialization or mode switching. The control device then comprehensively determines whether the liquid conditions required for the selected mode are met. By installing a first liquid level sensor in at least one ink cartridge, the solution of this application can achieve real-time monitoring and closed-loop control of ink and related liquid levels, reducing printing interruptions caused by liquid depletion, optimizing the timing of liquid replenishment and ink supply rhythm, and improving the controllability and stability of multi-mode printing system operation.

[0100] In some embodiments, such as Figure 6 As shown, the liquid filling assembly 140 includes a second liquid level sensor 144, which is used to detect the liquid level position in the liquid filling assembly 140.

[0101] The storage containers (1421, 1422) serve as the source of external liquid supply. The liquids such as ink, cleaning agents, or humectants stored inside must maintain a monitorable level during use and replenishment to ensure that the liquid supply assembly can promptly supply the required liquid to the corresponding ink cartridges in the ink cartridge assembly. The second liquid level sensor can detect changes in the liquid level in the storage containers in real time and provide the detection information to the control device so that the system can grasp the available amount of external liquid and respond in advance.

[0102] The second liquid level sensor can be installed on the side wall, bottom, or top of the storage container. Depending on the liquid type and container structure, it can be a contact or non-contact measurement method, such as using mature technologies like float switches, photoelectric level gauges, pressure-sensing level detection, or capacitive level detection. This allows changes in liquid level to be continuously or intermittently converted into identifiable signals. When the liquid in the storage containers (1421, 1422) is depleted to a set lower limit, the second liquid level sensor transmits a corresponding signal to the control component. The control component then determines whether the remaining liquid is sufficient to support subsequent refilling operations and, if necessary, issues a warning message or stops the operation of the relevant mode to prevent refilling interruptions or insufficient ink cartridge supply due to external liquid depletion.

[0103] When the system performs multi-mode printing tasks, the control device can combine the liquid level data provided by the second liquid level sensor with the liquid level information detected by the first liquid level sensor in the ink cartridge assembly 130 to jointly evaluate the working status of the entire liquid supply chain. For example, in the second printing mode, if the liquid level of the second ink cartridge 132 drops due to high-speed consumption, and the second liquid level sensor detects that the liquid level of the corresponding ink in the storage container is also close to the lower limit, the control component can prioritize completing the current lamination task or pause the operation, prompting the operator to replenish the ink in the storage container to avoid air suction or air resistance during the liquid replenishment process, which would affect the stability of the liquid supply. For cases where the storage containers contain liquids of different properties, a second liquid level sensor can be installed separately in each container or in the chamber of each type of liquid to achieve independent monitoring and classification management of the liquid levels, thereby enabling on-demand selection and replenishment during the scheduling of the liquid replenishment components.

[0104] By setting a second liquid level sensor in the liquid filling assembly, the solution of this application can reliably detect the liquid level status of the external liquid supply source and form a closed-loop control with the liquid level detection inside the ink cartridge. This enables the system to rationally plan the timing and sequence of liquid filling during multi-mode printing and maintenance operations, reduce work interruptions or liquid supply abnormalities caused by unknown external liquid levels, and improve the operational stability and automation of the multi-mode printing system under continuous production and frequent switching conditions.

[0105] Each storage container (1421, 1422) may be equipped with a liquid level indicator 145 to indicate the current liquid level (e.g., the light changes color from green to red when the liquid level is below a certain threshold). The outlet of each storage container (1421, 1422) is connected to the inlet of a liquid supply pump, and the outlet of the liquid supply pump is connected to a flow channel of the connection assembly connector on the filling station housing. The filling assembly is equipped with an identification element 1403 (such as an RFID tag), and the type identification device 160 may further include an electronic tag reader for identifying the identification element.

[0106] In some embodiments, as shown in FIG5, the liquid filling assembly 140 further includes a housing 141. The housing serves as a structural carrier for the liquid filling assembly, accommodating at least two storage containers and providing positioning and interface support for the docking of the storage containers with the liquid supply pipeline. The housing 141 has a first slot 1411 and a second slot 1412, respectively for placing the first storage container 1421 and the second storage container 1422. The first storage container 1421 contains one color of the first ink (or the second ink), and the second storage container 1422 contains another color of the first ink (or the second ink), or supporting material. The first slot 1411 has a first positioning mark 1431 (e.g., a specific slot shape), and the second slot 1412 has a second positioning mark 1432 (e.g., another slot shape or number). The storage containers (1421, 1422) are provided with structures that match the corresponding slot positioning marks to prevent users from inserting them incorrectly.

[0107] In some embodiments, either the first positioning mark 1431 or the second positioning mark 1432 is selected from at least one of visual marks, tactile marks, electronic marks, or physical error-proofing structures. The first positioning mark and the second positioning mark can effectively prevent users from adding the wrong ink, ensuring the accuracy of the printing material and the safety of the system.

[0108] The positioning markers can be implemented in various ways to achieve intuitive and reliable differentiation and prevent misoperation. For example, in one embodiment, the positioning markers can be combined with physical structure error-proofing design, such as having incompatible guide grooves or snap-fit ​​structures for the first and second slots, thereby physically preventing different storage containers from being mistakenly inserted into non-corresponding slots. In another embodiment, the first and second positioning markers are different visual markers, such as distinct color blocks, graphic symbols, or text labels. In yet another embodiment, the markers are tactile markers, such as marker blocks with different contours, textures, or embossed structures around the corresponding slots, allowing users to differentiate them by touch. Furthermore, the markers can also be electronic markers, such as detection resistors with different resistance values ​​or specific types of RFID tags installed in the slots, allowing the device to automatically identify the container type via detection circuitry or a reader when a storage container is inserted. These marking methods can be used individually or in combination to ensure that operators can quickly and accurately identify and load containers, avoiding misoperation. In some embodiments, the refill station identifier 1403 and the cartridge identifier 1303 can also employ at least one of visual markers, tactile markers, electronic markers, or physical error-proofing structures.

[0109] In some embodiments, the multi-mode printing system further includes a control device 150 and a type identification device 160. The type identification device maintains a communicative connection with the control device and is used to automatically acquire and determine the actual configuration of key components related to the printing function during system operation. The main function of the type identification device is to detect whether the printhead mounting assembly 111 of the printer body is currently equipped with the first printhead 121 or the second printhead 122, and / or to detect whether the printer body is equipped with the first ink cartridge 131 or the second ink cartridge 132, and / or to determine whether the ink filling assembly 140 has established a connection with the ink cartridge assembly 130 and formed an ink-available state.

[0110] By collecting and transmitting the above information, the control device can confirm whether the system hardware configuration matches the printing mode to be executed before startup or during mode switching, thereby avoiding abnormal operation or reduced printing quality due to component mismatch or missing parts.

[0111] The type identification device can be implemented using a near-field communication (NFC) antenna or similar means, and is positioned at a corresponding detection location on the printer body, such as the ink cartridge mounting location or the connection port of the refill assembly. Correspondingly, the first ink cartridge 131, the second ink cartridge 132, and the refill assembly 140 each integrate an NFC tag or other NFC-readable identifier (1203, 1303, 1403) at appropriate locations. The tag stores information characterizing the component type, model, ink type, applicable mode, and parameter setting range. Once the component is installed, the type identification device reads the tag data wirelessly and transmits it to the control component. The control component parses this information to determine the available printhead type, ink cartridge type, and refill assembly connection status of the current system, and automatically invokes the driver program, ink supply parameters, and path control logic matching the identified component.

[0112] The type identification device 160 can also be an electronic tag reader or a physical switch. For example... Figure 6 As shown, each ink cartridge (131, 132) is equipped with an identification element 1303 (such as an RFID tag or a specific shaped antenna). When an ink cartridge (131, 132) is installed into the ink cartridge installation slot 112, the type identification device 160 automatically reads its identification element 1303 and sends the information to the control device 150. Based on this, the control device 150 determines whether the currently installed ink cartridge 131 is the first ink cartridge 131 or the second ink cartridge 132, and loads the corresponding print driver, color management, or material parameter package accordingly. This automatic identification function eliminates the tedious steps of manual configuration by the user, effectively preventing printing failures or equipment damage caused by incorrect mode settings, and improving the system's security and automation level.

[0113] The identification of the first print head 121 and the second print head 122 can be achieved by sending a query command and obtaining the corresponding identification code or voltage signal for each print head.

[0114] After obtaining the identification result from the type identification device, the control device can automatically retrieve the software driver, process package, inkjet control parameters (including temperature, drive voltage, waveform file) and color characteristic file (ICC curve / file, International Color Consortium Curve / International Color Consortium Profile) that are completely matched to the type of printhead from the local database or cloud server, and complete the initial configuration of the printing program.

[0115] Upon successful identification, the control device executes an automatic adaptation process: First, a driver update is performed, which involves extracting a dedicated driver program corresponding to the printhead model from the resource library and replacing the original driver at the system level; then, a process package optimized for the printhead is loaded, covering parameter settings for maintenance processes such as cleaning, moisturizing, and ejection testing; next, a customized driver waveform file is applied, and key inkjet parameters such as optimal operating voltage and firing frequency are set; finally, a color characteristic file matching the printhead and the ink combination is called and injected into the color management engine to ensure the accuracy of color output.

[0116] This identification mechanism can be automatically executed during system power-on initialization or after printhead or ink cartridge replacement, requiring no manual input or additional settings, thus reducing operational complexity and the risk of human error. When the multi-mode printing system needs to switch from the first printing mode to the second printing mode, the type identification device can re-detect the actual assembly of the printhead mounting assembly 111 and the ink cartridge assembly 130, confirming that the second printhead 122 and the second ink cartridge 132 are correctly installed and in a usable state. Simultaneously, it verifies whether the liquid filling assembly 140 is connected to the second ink cartridge 132, ensuring the stability and continuity of ink supply during subsequent 3D printing. If the detection reveals that the component type does not match the expected mode or the connection is incomplete, the control device can issue a prompt or prevent mode switching to avoid printhead damage, ink cross-contamination, or molding failure due to hardware configuration errors. By introducing a collaborative working mechanism between the type identification device and the control device into the multi-mode printing system, automatic identification and configuration verification of key components can be achieved, improving the reliability of system operation and the accuracy of mode switching, and providing the necessary information foundation for the automated control of the multi-mode printing process.

[0117] In some embodiments of this application, such as Figure 1As shown in Figures -2 and 10-11, all fluid circuit connections in the multi-mode printing system are achieved using ink tubes. Ink tube 181 connects the printhead and ink cartridge, while ink tube 182 connects the ink cartridge and the refill assembly. The connection method between the ink tubes and each component can be configured as detachable or non-detachable according to design requirements. For example, the first ink tube can detachably or non-detachably connect the first printhead and the first ink cartridge; the second ink tube can detachably or non-detachably connect the second printhead and the second ink cartridge; or, the third ink tube can detachably or non-detachably connect the ink cartridge and the refill assembly. In the detachable connection configuration, the connection between the ink tubes and each component is achieved using precision connecting components 190, which include a male connector 191 and a female connector 192. As shown in Figure 2, one end of the ink tube connecting the printhead and the ink cartridge (regardless of the number of printheads or ink cartridges) is directly connected to the printhead, and the other end is provided with a male connector of the connecting component. This male connector is connected to the female connector of the connecting component on the ink cartridge (or one end of the ink tube is a female connector, and the ink cartridge is provided with a male connector) to form a sealed liquid path; while the second ink tube connecting the ink cartridge and the liquid filling component has male (or female) connectors of the connecting component at both ends. One end is connected to the female (or male) connector on the ink cartridge, and the other end is connected to the female (or male) connector of the liquid filling component to realize a sealed liquid path between the liquid filling component and the ink cartridge.

[0118] In some embodiments, the male connector of the first ink tube is detachably connected to the female connector of the first ink cartridge; or the male connector of the second ink tube is detachably connected to the female connector of the second ink cartridge; or the male connector of one end of the third ink tube is detachably connected to the female connector of the ink cartridge assembly, and the male connector of the other end of the third ink tube is detachably connected to the female connector of the refilling assembly.

[0119] In some embodiments, the multi-mode printing system further includes at least one valve, which can be installed at at least one of the following locations: ink tube 181 (first ink tube, second ink tube), ink tube 182 (third ink tube), first ink cartridge 131, second ink cartridge 132, or liquid filling assembly 140, for controlling the opening or closing of the corresponding flow path. The type and installation location of the valve are determined according to the system's ink supply and leak prevention requirements. Its function is to close the flow path when needed to prevent leakage, backflow, or crossflow of ink or other working fluids, and to open the flow path when needed to allow ink to flow normally between system components in a set direction and flow rate.

[0120] At the piping level, a valve can be located in the middle or near the end of ink tube one to control the ink supply between the first ink cartridge 131 and the first print head 121, or between the second ink cartridge 132 and the second print head 122. This allows the flow path to be isolated by closing the corresponding valve during print head replacement, cleaning, or mode switching, preventing ink from stagnating or leaking in the piping. Simultaneously, the valve is opened again before printing to establish ink supply, ensuring a stable ejection process. A valve on ink tube two 182 can be located at the connection between the ink cartridge assembly 130 and the liquid filling assembly 140. It controls the start and stop of liquid filling and the switching of liquid replenishment paths between different containing units, preventing accidental supply when liquid filling is not required or when switching liquid types.

[0121] At the component level, valves installed in the first and second ink cartridges can be located at the inlet and outlet of the receiving unit. These valves control the timing and flow rate of liquid output from or input to the receiving unit, and work in conjunction with the first liquid level sensor and control device to automatically cut off flow and provide an alert when the liquid level is insufficient. Similarly, valves installed in the liquid filling assembly 140 can be located at the inlet and outlet of the storage container. These valves control the timing and flow rate of liquid output from the storage container of the receiving unit, and work in conjunction with the second liquid level sensor and control device to automatically cut off flow and provide an alert when the liquid level is insufficient. The valves can be configured as solenoid valves, mechanical shut-off valves, check valves, or pinch valves, and the appropriate type can be selected based on the liquid properties, operating pressure, and response speed requirements. Their opening and closing actions can be driven by the control component based on the operating mode, liquid level detection results, or maintenance commands.

[0122] By installing a valve at at least once and configuring it to prevent ink leakage in the closed state and allow ink flow in the open state, the solution of this application can precisely control the flow path during the operation, switching and maintenance of a multi-mode printing system, effectively avoiding unintended mixing between different inks, liquid leakage during shutdown, and jetting abnormalities caused by residual pressure in the pipeline, thereby improving the sealing reliability and operational safety of the system, and reducing the increase in maintenance costs caused by liquid waste or contamination.

[0123] In some embodiments, such as Figure 11As shown, the male connector 191 includes a male connector body 1911, on which multiple independent flow channels 1912 are provided (the number of which corresponds to the number of ink storage units in the ink cartridge). The female connector includes a female connector body 1921, on which multiple independent flow channels 1922 are provided (the number of which corresponds to the number of ink receiving units in the ink cartridge). When the female and male connectors are connected, the female connector flow channels and the corresponding male connector flow channels are connected and simultaneously conductive. When the female and male connectors are separated, the female connector flow channels and the corresponding male connector flow channels are simultaneously disconnected. At least one of the female and male connectors has an elastic element 1923 (such as a spring), a valve core 1924, and a sealing ring 1925 installed in each flow channel. The valve core 1924 is axially movable along the flow channel. One end of the elastic element 1923 is fixed to the flow channel wall, and the other end abuts against the valve core 1924. The sealing ring is positioned where the valve core and the flow channel wall can contact each other. Under normal conditions, the elastic force of the elastic element 1923 causes the valve core 1924 to contact and compress the sealing ring to block the flow channel and prevent internal ink from flowing out. When the male connector body is inserted into the female connector body, the end of the male connector body pushes against the valve core 1924, overcoming the force of the elastic element 1923 and causing displacement. This creates a gap between the valve core and the flow channel wall, allowing liquid to pass through, thereby opening the liquid path and connecting the male connector body 1911 and the female connector body 1912. This connection method not only achieves fast and reliable connection and disconnection, but more importantly, it can automatically seal instantly when disconnected, completely avoiding the problems of ink dripping, contaminating equipment and the working environment during ink replacement operations.

[0124] In addition, the male or female connector body can be equipped with an automatic locking structure. When the two are connected, the automatic locking mechanism prevents the male connector body from accidentally coming off and ensures the stability of the connection during the operation of the ink system.

[0125] In some embodiments, such as Figure 8-9As shown, the printhead mounting assembly 111 includes a base 1111, an electrical interface 1112, and a quick-release fixing module 1113. The electrical interface 1112 establishes an electrical connection with the printhead, transmitting control signals and power. The fixing module 1113 allows users to quickly and securely install or remove the printhead without tools. This design significantly simplifies the printhead replacement process, reducing the user's operational threshold and maintenance time. The printhead mounting assembly 111 can selectively connect different types of printheads (such as a first printhead suitable for 2D printing and a second printhead suitable for 3D printing) to the same electrical interface and fixing module. In other words, it can be compatible with different printheads through the same interface, requiring only one installation structure and corresponding control device, thus avoiding system structural redundancy. When the first print head 121 or the second print head 122 is installed into the print head mounting assembly 111 and in place, the electrical interface 1112 forms an electrical connection with the electrical connector of the print head, and the quick-release fixing module 1113 mechanically fixes the print head to maintain a stable position during printing, so that it does not undergo axial or radial displacement, nor does it fall off due to vibration or external force.

[0126] The base 1111 serves as the main support for the printhead mounting assembly 111, providing an installation reference and mechanical strength guarantee for the electrical interface 1112 and the quick-release fixing module 1113. The quick-release fixing module 1113 has a slot structure along a specific direction, allowing the first printhead 121 or the second printhead 122 to be inserted axially into the slot until the printhead body abuts against a preset positioning surface. A mechanical locking mechanism is provided inside the slot. This mechanism is automatically or manually triggered after the printhead is inserted, securely locking the printhead within the slot to prevent displacement during operation due to inertia, media reaction force, or external collisions. The specific structure and working principle of the locking mechanism can employ well-established solutions known in the art, such as spring clips, eccentric wheel locks, rotary knobs, or lever clamping structures, aiming to achieve a balance between quick installation / removal and reliable fixation.

[0127] The electrical interface 1112 is located on one side of the quick-release fixing module 1113. Its position and shape match the electrical connector of the inserted nozzle, enabling stable contact and establishing a signal transmission path when the nozzle is installed. This signal path is used not only to transmit drive pulses, waveform parameters, and status control signals to the nozzle, but also to receive temperature, operating status, and fault information from the nozzle. Based on this, the electrical interface 1112 works with the identification unit inside the nozzle to automatically identify the type of the connected nozzle. Identification methods include, but are not limited to, reading the nozzle model identification code ID pre-stored in a non-volatile memory chip built into the nozzle, such as an EEPROM (Electrically Erasable Programmable Read-Only Memory); detecting the electrical response characteristics of the nozzle under specific voltage or current excitation conditions; parsing the protocol field information exchanged between the nozzle and the control component during the communication handshake; or reading the type and parameter data stored in a tag attached to the nozzle surface via a near-field communication module, such as NFC.

[0128] In some embodiments, the quick-release fixing module cooperates with the movable module of the first or second printhead to achieve mechanical fixation. The movable module has a second mating structure, and the fixing module 1113 has a first mating structure adapted to the second mating structure. The first and second mating structures form a guiding and positioning fit to achieve docking. The quick-release fixing module 1113 also includes a locking actuator and an operating component (e.g., a handle). The operating component drives the locking actuator to form a locking or unlocking fit with the movable module.

[0129] Overall implementation process: The operator aligns the movable module of the first or second printhead with the quick-release fixing module 1113. Through the guiding and positioning effect of the first and second mating structures, the printhead is precisely connected. At this time, the electrical interface 1112 is electrically connected to the electrical interface 121 of the first or second printhead. Then, the technician operates the handle to drive the locking actuator to engage with the movable module, thus securing the printhead. When the printhead needs to be replaced, the technician reverses the operation of the handle to unlock the locking actuator, allowing the printhead to be removed along the guide direction for quick disassembly and assembly.

[0130] In some embodiments, the first mating structure is a groove structure, and the second mating structure is a guide rail structure adapted to the groove structure. The guide rail structure and the groove structure 1 slide together to achieve guiding and positioning.

[0131] Optionally, the groove structure can be a dovetail groove, and the guide rail structure can be a dovetail guide rail adapted to the dovetail groove. The dovetail guide rail is fixedly installed on the first print head or the second print head.

[0132] This embodiment improves the guiding and positioning effect of the print head during installation by sliding the guide rail and the groove, reducing jamming and misalignment during installation, and lowering the probability of poor contact of electrical interfaces due to docking deviation.

[0133] In some embodiments, the second mating structure is a locking block with a positioning groove, and the first mating structure includes a positioning structure (such as a snap-fit ​​interface) that engages with the positioning groove. The positioning structure engages with the positioning groove to achieve guiding positioning.

[0134] Optionally, the locking block is fixedly installed on the first print head or the second print head.

[0135] This embodiment improves the guiding and positioning effect during printhead installation by engaging a locking block with a positioning groove and a matching positioning structure, reducing jamming and misalignment during installation, and lowering the probability of poor contact due to misalignment of electrical interfaces.

[0136] After obtaining the identification result, the control component can automatically match the drive parameters, jetting sequence, ink supply pressure, and path planning strategy corresponding to the printhead. When necessary, it can also link the ink cartridge component 130 to switch the ink supply source and the working mode of the liquid filling component 140, thereby completing the preset and preparation of the printing mode without manual parameter configuration or hardware adjustment. This mechanism enables the system to quickly enter a usable state after replacing the first printhead 121 or the second printhead 122, reducing operational anomalies caused by manual identification errors or improper settings. It improves the adaptability and operational reliability of the multi-mode printing system in different printhead replacement scenarios, and also provides structural and control-level support for printhead maintenance, upkeep, and multi-task switching.

[0137] This application also provides a method for use in a multi-mode printing system, which enables switching and collaborative operation between different printing modes on the same device, thereby improving the adaptability and efficiency of the device in diverse processing tasks. Specifically, it includes the following steps: A printer body 110 is provided, which includes a printhead mounting assembly 111 for interchangeably mounting different types of printheads and providing positioning, fixing and electrical connection conditions for the printheads.

[0138] A printhead assembly 120 is provided, which includes a printhead; An ink cartridge assembly 130 is provided, which is used to hold a first ink and / or a second ink; the first ink and the second ink are different. The selection of the first ink and the second ink can be referred to the content in the foregoing embodiments, and will not be repeated here.

[0139] Switching between printing modes includes: starting the first printing mode and controlling the ink cartridge assembly 130 to supply first ink to the print head installed in the print head mounting assembly 111 to perform 2D printing or 2.5D printing. When switching from the first printing mode to the second printing mode, the ink cartridge assembly 130 supplies second ink to the print head mounted on the print head mounting assembly 111 to perform 3D printing.

[0140] In this embodiment, the first ink is used for printing in a first mode, such as 2D printing or 2.5D printing; the second ink is used for printing in a second mode, such as 3D printing. Using the same system control method, flexible switching and coordinated use of 2D printing, 2.5D printing, or 3D printing can be selectively achieved, which is convenient, fast, simple to operate, and cost-effective.

[0141] In some embodiments, the second ink can also be used to perform 2D printing or 2.5D printing.

[0142] The printhead assembly 120 may include a first printhead 121 and a second printhead 122. These two printheads correspond to different printing mode requirements in terms of structural parameters, driving methods, and applicable ink types. In actual use, at least one of the first printhead 121 and the second printhead 122 can be selectively installed onto the printhead mounting assembly 111 according to the type of task to be performed, ensuring a stable mechanical fixation and reliable electrical connection after installation. The first printhead is used to execute a first printing mode, and the second printhead is used to execute a second printing mode.

[0143] The ink cartridge assembly 130 may include a first ink cartridge 131 and a second ink cartridge 132. The first ink cartridge 131 is used to hold a first ink, and the second ink cartridge 132 is used to hold a second ink. The first ink and the second ink differ in composition, viscosity, curing method, or color properties, and are adapted to different printing modes and process requirements. The first ink cartridge 131 cooperates with the first print head 121 to form a two-dimensional printed image on the surface of an object, or to form a three-dimensional relief texture structure with a limited height by adjusting the ink layer thickness. The second ink cartridge 132 cooperates with the second print head 122 to form a three-dimensional solid object by layering materials.

[0144] When the first printing mode is started, the control device confirms that the first print head 121 has been correctly installed in the print head mounting assembly 111 based on the installation information fed back by the type identification device, and controls the ink supply channel between the first ink cartridge 131 and the first print head 121 to open, so that the first ink is delivered to the first print head 121 as needed. The print head performs ejection according to the 2D printing or 2.5D printing path and ink volume control strategy to complete the processing of the corresponding graphics or textures.

[0145] When switching from the first printing mode to the second printing mode, the control device first terminates the ejection operation of the first print head 121 and performs the necessary cleaning or sealing process. Then, the second print head 122 is installed into the print head mounting assembly 111, ensuring that the quick-release fixing module 1113 is mechanically locked and that the electrical interface 1112 is connected to the electrical connector of the second print head 122. At the same time, the control device switches the ink supply channel to connect the fluid path between the second ink cartridge 132 and the second print head 122, and controls the delivery and ejection of the second ink according to the lamination path and material supply strategy of the second printing mode, thereby stacking layer by layer on the processing platform to form a three-dimensional object.

[0146] In some embodiments, the printhead assembly includes a first printhead and a second printhead; the ink cartridge assembly includes a first ink cartridge and a second ink cartridge; when switching from a first printing mode to a second printing mode, switching between the printhead performing the printing task and the ink cartridge performing the printing task includes: The printhead performing the printing task is switched from the first printhead to the second printhead, and the ink cartridge performing the printing task is switched from the first ink cartridge to the second ink cartridge; wherein, the first ink cartridge supplies first ink to the first printhead installed in the printhead mounting assembly; and the second ink cartridge supplies second ink to the second printhead installed in the printhead mounting assembly.

[0147] In some embodiments, switching the printhead performing the printing task from a first printhead to a second printhead includes: removing the first printhead from the printhead mounting assembly and installing the second printhead in the same location; or Switching from controlling the first printhead to controlling the second printhead to eject ink, wherein both the first and second printheads are mounted on the printhead mounting assembly.

[0148] In some embodiments, switching the ink cartridge performing the printing task from a first ink cartridge to a second ink cartridge includes: removing the first ink cartridge from the printer body and installing the second ink cartridge in the same location; or The control switches from supplying the first ink cartridge with the first ink to supplying the second ink cartridge with the second ink, wherein the first and second ink cartridges are installed in the printer body simultaneously.

[0149] In some embodiments, the printhead assembly includes only one printhead, and the method further includes: providing a first cleaning component; when switching from a first printing mode to a second printing mode, using the first cleaning component to clean the printhead to remove first ink from the printhead; and supplying second ink to the cleaned printhead.

[0150] In some embodiments, the ink cartridge assembly includes only one ink cartridge, and the method further includes: providing a second cleaning component, which cleans the ink cartridge to remove the first ink in the ink cartridge when switching from the first printing mode to the second printing mode; and supplying the second ink to the cleaned ink cartridge.

[0151] In the above method, the execution of each step can be assisted by a liquid level sensor, a refilling assembly 140, and a positioning marker. For example, the liquid level of the second ink cartridge 132 can be detected before switching, and ink can be added by the refilling assembly 140 if necessary. Alternatively, when installing the printhead and ink cartridge, the compatibility of the components can be automatically verified by a type identification device to avoid abnormal operation due to incorrect installation or insufficient ink supply. The refilling assembly is connected to the ink cartridge assembly; ink is supplied to the ink cartridge assembly using the refilling assembly.

[0152] By enabling selective installation of printheads and ink cartridges, switching of ink supply channels, and automatic identification and parameter matching of modes at the hardware configuration and software control levels, this method can complete the functional coverage from 2D planar graphic output and 2.5D relief texture construction to 3D solid modeling in a single multi-mode printing system. This reduces redundant equipment investment and space occupation, and improves the response speed of task switching and the continuity of operation, thereby expanding the practical value of printing technology in cross-domain manufacturing and creative applications.

[0153] The above method introduces a collaborative working mechanism between the control device and the type recognition device during the execution process. This mechanism is used to automatically obtain information related to the actual configuration of key components before the system runs or when switching modes, and to complete the matching and configuration of the printing program accordingly.

[0154] In some embodiments, a type identification device is used to determine whether the currently installed printhead on the printhead mounting assembly of the printer body is a first printhead or a second printhead, and / or whether the currently installed ink cartridge on the printer body is a first ink cartridge or a second ink cartridge; and the corresponding print parameter data packet is obtained based on the determination result to complete the configuration of the printing program.

[0155] In some embodiments, a type identification device is used to determine whether the printhead mounting assembly of the printer body is currently installing a first printhead or a second printhead, and / or whether the ink cartridge currently installed in the printer body is a first ink cartridge or a second ink cartridge; and / or whether the ink filling assembly is connected to the ink cartridge assembly; and based on the determination result, the corresponding printing parameter data packet is obtained to complete the configuration of the printing program.

[0156] The specific process is as follows: During the system initialization phase or after the printhead and ink cartridge replacement is completed, the type identification device detects the printhead mounting assembly of the printer body to determine whether the first printhead 121 or the second printhead 122 is currently installed, and / or detects the ink cartridge mounting compartment of the printer body to determine whether the first ink cartridge 131 or the second ink cartridge 132 is installed, and / or detects the connection status between the liquid filling assembly 140 and the ink cartridge assembly 130 to determine whether a connection relationship for ink supply has been formed.

[0157] The type identification device can employ near-field communication devices such as NFC antennas. The first printhead 121, second printhead 122, first ink cartridge 131, second ink cartridge 132, and dispensing assembly 140 each integrate identification information, including component type, model, applicable ink properties, supported modes, and parameter ranges, at appropriate locations. This information may be stored in a non-volatile memory chip or an NFC tag. After reading the corresponding identification information, the type identification device transmits the detection result to the control device in the form of an electrical signal or data frame. The control device analyzes the received information to identify the specific types of printheads and ink cartridges, the types of inks available, the connection validity of the dispensing assembly 140, and whether each component meets the operating conditions of the current or target printing mode.

[0158] Based on the above configuration information, the control device retrieves the data packet corresponding to the detection result. This data packet contains drive parameters, ink supply control logic, path planning algorithm, printhead temperature and voltage settings, jet frequency and ink volume mapping table, and cleaning and moisturizing process instructions required for different modes, all applicable to the identified printhead and ink cartridge combination. The control device loads this data packet into its running memory and initializes the printhead drive module, ink supply module, and motion control module according to the configuration information within, putting the system into a working state that matches the current hardware configuration, thereby completing the automatic configuration of the printing program. This process requires no manual intervention, avoiding print quality degradation, printhead damage, or operational interruption caused by manual setting errors or parameter mismatches.

[0159] Through the above mechanism, the method can obtain accurate component information and match appropriate program configuration in a timely manner after each printhead or ink cartridge replacement or when the connection status of the liquid filling component changes. This ensures that the hardware resources and software parameters remain consistent and coordinated when the multi-mode printing system switches between the first and second printing modes, thereby improving the reliability, switching efficiency and overall adaptability of the system operation, and providing stable automated support for multi-task production scenarios.

[0160] In some embodiments of this application, the method further includes a step of detecting the liquid level in the first ink cartridge 131 and the second ink cartridge 132, so as to monitor the available liquid level in the cartridges in real time and provide timely alerts when the liquid level drops to a level that may affect normal printing operations. Specifically, at least one of the first ink cartridge 131 and the second ink cartridge 132 is equipped with a first liquid level sensor. This first liquid level sensor continuously or periodically detects the liquid level in the corresponding ink cartridge according to a selected measurement principle, and converts the detected liquid level height or state into a recognizable signal and transmits it to the control component. The control component compares the received liquid level signal with a preset threshold, which is preset based on the ink consumption rate, cartridge volume, and printing mode requirements for ink supply continuity, to define the minimum liquid level limit at which the cartridge can still supply liquid normally.

[0161] When the first liquid level sensor detects that the liquid level is below a certain threshold, the control component determines that the liquid level in the corresponding ink cartridge is insufficient to maintain a stable ink supply in the current mode. It then generates a replenishment prompt and outputs it to the user interface or an external indicator to remind the operator to replenish the ink in time. For ink cartridges with multi-capacity units, a first liquid level sensor can be set up in each capacity unit and the threshold can be compared independently. This allows for separate monitoring and prompting of the levels of different types of inks, cleaning agents, or humectants, preventing the depletion of a particular type of liquid from affecting specific process steps. The replenishment prompt can be displayed as a light alarm, on-screen text prompt, buzzer, or a data message sent to a remote monitoring terminal. Its purpose is to attract the operator's attention and clearly identify the ink cartridge and liquid type requiring replenishment.

[0162] When the multi-mode printing system has a liquid filling assembly 140 connected to the ink cartridge assembly 130, the control device can automatically initiate the liquid filling process simultaneously with or after sending a prompt, based on the liquid level detection result and the operating status of the liquid filling assembly. The liquid filling assembly's storage container replenishes the ink cartridge holding unit with a liquid level below the threshold through the third ink tube, restoring the liquid level to the working range. This shortens downtime caused by ink shortage and maintains the continuity of printing operations. For the second ink cartridge 132 in the second printing mode, due to its higher ink consumption rate, the control component can combine the liquid level information of the storage container in the liquid filling assembly 140 detected by the second liquid level sensor to issue a prompt in advance when it is predicted that the second ink cartridge 132 will run out of ink before the storage container, thus avoiding the situation where insufficient external liquid prevents the completion of liquid filling during the process.

[0163] By introducing a liquid level detection and threshold comparison mechanism into the method, and sending a replenishment prompt when the liquid level is below the threshold, the multi-mode printing system can effectively monitor the ink and functional liquid levels during operation, reduce printing interruptions, nozzle dry runs, or forming defects caused by liquid depletion, and provide a basis for timely replenishment or automatic liquid addition, thereby improving the continuity of operation and operational reliability of the system.

[0164] In some embodiments, the method further includes a step of detecting the liquid level in the storage container of the liquid filling assembly 140 to determine the liquid level status of the external liquid supply source and to issue a timely warning when the liquid level drops to a level that may affect the liquid filling operation. Specifically, the liquid filling assembly 140 is equipped with a second liquid level sensor. This second liquid level sensor continuously or periodically detects the liquid level in the storage container according to a selected measurement principle and converts the detected liquid level height or liquid level status into a recognizable signal, which is then transmitted to the control device. After receiving the liquid level signal, the control device compares it with a threshold preset for the storage container. This threshold is determined based on the volume of the storage container, the consumption rate of the loaded liquid, and the liquid filling strategy, and represents the lowest liquid level limit at which the liquid in the container can still be supplied normally.

[0165] When the second liquid level sensor detects that the liquid level is below the threshold, the control device determines that the liquid level in the storage container is insufficient to stably supply the corresponding receiving unit of the ink cartridge assembly. It then generates a warning signal and outputs it to the user interface, indicator light, display screen, or remote monitoring terminal to prompt the operator to replenish the corresponding liquid in a timely manner. In cases where the refill assembly has multiple storage containers, a second liquid level sensor can be configured in each container and threshold comparisons can be performed independently. This allows for separate monitoring and warning of the liquid levels of different types of liquids, preventing refill interruptions or ink supply errors due to the depletion of a particular type of liquid. The warning signal can take the form of an audible and visual alarm, text or graphic prompts, or data packets transmitted over a network. Its purpose is to clearly indicate the storage container requiring replenishment and the type of liquid, facilitating rapid replenishment by the operator.

[0166] When the multi-mode printing system and ink cartridge assembly are connected and have automatic liquid filling function, the control device can also issue a warning signal while simultaneously or after the warning signal to initiate protective control, such as pausing the automatic liquid filling process or restricting the start of new printing tasks, to prevent problems such as air suction, air resistance, or unstable liquid supply when the liquid in the storage container is insufficient. For continuous molding tasks in the second printing mode, the control device can combine the detection results of the first liquid level sensor of the second ink cartridge 132 with the liquid level information of the second liquid level sensor to issue a warning in advance when it is predicted that the liquid replenishment demand of the second ink cartridge 132 will exceed the available liquid volume of the storage containers (1421, 1422), thereby giving the operator more time to prepare for liquid replenishment and avoiding interlayer defects or work stoppage caused by external liquid supply interruption during the molding process.

[0167] By introducing a detection and threshold judgment mechanism for the liquid level in the storage container into the method, and issuing a prompt signal when the liquid level is below the threshold, the multi-mode printing system can effectively monitor the amount of external liquid supply during operation and liquid replenishment, reduce liquid supply abnormalities and printing interruptions caused by insufficient liquid, and provide a basis for timely liquid replenishment and maintaining the stability of the liquid replenishment process, thereby improving the system's operational continuity and overall operational reliability.

[0168] In some embodiments, the method further includes at least one of the following steps: detachably or non-detachably connecting the first printhead and the first ink cartridge using a first ink tube; detachably or non-detachably connecting the second printhead and the second ink cartridge using a second ink tube; or detachably or non-detachably connecting the ink cartridge and the refill assembly using a third ink tube.

[0169] In some embodiments, the printhead mounting assembly includes a base, an electrical interface, and a quick-release fixing module, wherein the electrical interface and the quick-release fixing module are mounted on the base; when one of the first printhead and the second printhead is selectively mounted to the printhead mounting assembly, the electrical interface is electrically connected to the first printhead or the second printhead, and the quick-release fixing module secures the first printhead or the second printhead.

[0170] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
