Description

Technical Field

[0001] This application relates to the field of multidimensional printing technology, specifically to a multidimensional printing component, a hot end, an extruder, and a multidimensional printing device. Background Technology

[0002] Multidimensional printing, such as 2D, 3D, and 4D printing, refers to the method of printing complex geometric models using one or more materials. Also known as additive manufacturing, multidimensional printing is a technology that creates three-dimensional objects by adding materials layer by layer. Unlike traditional subtractive manufacturing (such as cutting and milling), multidimensional printing starts with a computer model and builds an object by gradually accumulating materials. This technology has a wide range of applications, covering multiple fields including manufacturing, medicine, architecture, art, and education.

[0003] In the 3D printing process, different materials are often required. Current technology typically involves using multiple tool heads, each corresponding to a specific material, to meet the needs of different materials, but this results in higher costs. Alternatively, a single tool head can be used to switch feeding methods to meet the needs of different materials. This method eliminates the need for multiple tool heads, thus reducing costs, but it leads to higher material waste. Summary of the Invention

[0004] This application provides a multidimensional printing component, a hot end, an extruder, and a multidimensional printing device, which helps to reduce the cost of multidimensional printing and the waste of materials, and enables the cost and material waste to be in a relatively balanced state.

[0005] This application provides a multidimensional printing component, including:

[0006] An extruder has a feed channel and an installation area.

[0007] At least two different hot ends, each hot end forming a discharge channel, the discharge channels of the different hot ends being used to accommodate different materials, each hot end being provided with a mating part adapted to the mounting area, and the mounting area being detachably connected to the at least two mating parts respectively, so that the feed channel of the extruder is alternately connected to the discharge channels of the at least two hot ends, thereby enabling the extruder to convey different materials to the discharge channels of the different hot ends.

[0008] By adopting the above technical solution, the mating parts of different hot ends can be detachably connected to the installation area of ​​the extruder, and the discharge channels of different hot ends are used to accommodate different materials. Therefore, by replacing the hot ends connected to the extruder, the extruder can transport different materials to the discharge channels of different hot ends, enabling the use of different materials. In other words, this application, by providing at least two hot ends, and the extruder being detachably connected to at least two hot ends, allows the extruder's feed channel to alternately connect with the discharge channels of different hot ends, thereby enabling the transport of different materials to the discharge channels of different hot ends. This meets the needs of using different materials without replacing the entire multi-dimensional printing assembly, which helps reduce the cost of multi-dimensional printing.

[0009] In one embodiment of this application, the extruder includes a body and a connector. The connector is located in the mounting area and can switch between a first state and a second state. In the first state, the connector is fixedly connected to the hot end and the body. In the second state, the hot end can move relative to the body.

[0010] By adopting the above technical solution, by placing the connector in the first state, the hot end and the body can be fixedly connected, realizing the connection between the hot end and the extruder, and ensuring stable communication between the feed channel of the extruder and the discharge channel of the hot end; when a new hot end needs to be replaced, the connector is placed in the second state, at which time the current hot end can be moved relative to the body, that is, the current hot end can be removed from the extruder, and then the new hot end is placed in the installation area, and the connector is placed in the first state again, so that the new hot end and the extruder are fixedly connected.

[0011] In one embodiment of this application, the mating part has a magnetic element, and the connector includes an electromagnet. In a first state, the electromagnet is energized and attracts the magnetic element, and in a second state, the electromagnet is de-energized and the magnetic element can detach from the electromagnet.

[0012] By adopting the above technical solution, when the hot end and the extruder need to be connected, the connector is in a first state, i.e., the electromagnet is energized. In this state, the electromagnet generates magnetic force to attract the magnetic component of the mating part, connecting the magnetic component and the electromagnet together, thus achieving the connection between the hot end and the extruder via the connector. When the hot end needs to be removed from the extruder, the connector is in a second state, i.e., the electromagnet is de-energized. In this state, the electromagnet loses its magnetic force and no longer attracts the magnetic component of the mating part, allowing the mating part to move relative to the electromagnet, i.e., the hot end can move relative to the extruder. In other words, this application achieves the connection between the hot end and the extruder through the cooperation of the electromagnet and the magnetic component, resulting in a simple structure. Furthermore, controlling the connection between the hot end and the extruder can be achieved simply by controlling the energization state of the electromagnet, making it easy and convenient.

[0013] In one embodiment of this application, the multidimensional printing component further includes a control component, which is connected to an electromagnet and is used to control the electromagnet to switch between an energized state and an de-energized state.

[0014] The control component is connected to the main body, and the control component and the installation area are separated.

[0015] By adopting the above technical solution, the energizing state of the electromagnet can be controlled by the control component, and the connector can be switched between the first and second states by the control component. Simultaneously, by spacing the control component and the installation area apart, the space occupied by the control component in the installation area can be avoided, interference between the control component and the hot end can be prevented, and the hot end can be smoothly installed in the installation area.

[0016] In one embodiment of this application, the mating portion is formed with a mounting groove, and the magnetic element is disposed in the mounting groove.

[0017] By adopting the above technical solution, the mounting groove can limit the magnetic component, improving its installation stability. Furthermore, by using the mounting groove to install the magnetic component, at least a portion of the component will be located within the groove, effectively reducing the protrusion length of the magnetic component beyond the mating part and simplifying the structure of the hot end.

[0018] In one embodiment of this application, the mating portion also has a notch communicating with the mounting groove.

[0019] By adopting the above technical solution, and by providing a notch that communicates with the mounting groove, the notch can provide clearance when installing the magnetic component, so as to facilitate the installation of the magnetic component in the mounting groove, thereby improving the ease of installation of the magnetic component; when removing the magnetic component, external force can be applied to the magnetic component through the notch, so that the magnetic component is detached from the mounting groove, thereby improving the ease of removal of the magnetic component.

[0020] In one embodiment of this application, the connector includes a first snap-fit ​​structure and a second snap-fit ​​structure is formed on the hot end; in a first state, the first snap-fit ​​structure and the second snap-fit ​​structure are snapped together to fix the hot end and the body.

[0021] By adopting the above technical solution, when it is necessary to connect the hot end and the body, the first snap-fit ​​structure and the second snap-fit ​​structure are engaged to connect the first snap-fit ​​structure and the second snap-fit ​​structure together, thereby fixing the hot end and the body together and realizing the snap-fit ​​connection between the hot end and the extruder. When it is necessary to disassemble the hot end, the first snap-fit ​​structure and the second snap-fit ​​structure are disengaged and contact each other, and the hot end can move relative to the body, thereby realizing the disassembly of the hot end. This makes the hot end detachably connected to the extruder, and the disassembly and assembly of the hot end is convenient.

[0022] In one embodiment of this application, the extruder is provided with a connecting end for connection with a hot end, and the mounting area includes a mounting space formed in the connecting end of the extruder. The shape of the mating part is adapted to the mounting space, and the mating part is accommodated in the mounting space.

[0023] By adopting the above technical solution, an installation space is formed at the connection end of the extruder, so that the hot end, whose shape matches the installation space, can be set in the installation space, ensuring that the hot end can be connected to the extruder.

[0024] In one embodiment of this application, the connecting end includes a first connecting portion and a second connecting portion connected in sequence. The first connecting portion extends along a first direction, and the second connecting portion extends along a second direction. The first direction and the second direction intersect, and an installation space is formed between the first connecting portion and the second connecting portion.

[0025] By adopting the above technical solution, the first end of the first connecting part is connected to the first end of the second connecting part, the second end of the first connecting part extends along the first direction, the second end of the second connecting part extends along the second direction, and there is an angle greater than 0° between the extension direction of the second end of the first connecting part and the extension direction of the second end of the second connecting part. Then, an installation space will be formed between the second end of the first connecting part and the second end of the second connecting part, so that the hot end can be accommodated in the installation space.

[0026] In one embodiment of this application, the multi-dimensional printing component further includes at least one positioning element disposed in the mounting area. The positioning element is used to position the mating part so that the mating part and the mounting area cooperate.

[0027] By adopting the above technical solution, the positioning component can position the mating part of the hot end, so that the mating part of the hot end can smoothly cooperate with the installation area of ​​the extruder, and realize the connection and cooperation between the hot end and the extruder.

[0028] In one embodiment of this application, a positioning member is connected to an extruder, and a first guide surface is formed at the end of the positioning member facing away from the extruder. The first guide surface is used to guide the mating part and the positioning member to cooperate.

[0029] By adopting the above technical solution, the first guide surface can guide the mating part to cooperate with the positioning member, so that the positioning member can position the mating part at the hot end.

[0030] In one embodiment of this application, the mating part is formed with a positioning hole, and a positioning member can be inserted into the positioning hole to position the mating part.

[0031] By adopting the above technical solution, a positioning hole adapted to the positioning member is formed in the mating part, so that the positioning member can be inserted into the mating part to achieve positioning of the mating part.

[0032] In one embodiment of this application, a second guide surface is formed at the opening of the positioning hole, and the second guide surface is used to guide the positioning member to be inserted into the positioning hole.

[0033] By adopting the above technical solution, by setting a second guide surface at the opening of the positioning hole, when the hot end is installed in the installation area, the second guide surface can guide the positioning component and guide the positioning component to be inserted into the positioning hole, so that the positioning component can smoothly and quickly cooperate with the positioning hole to achieve the positioning of the hot end.

[0034] In one embodiment of this application, the nozzles at different hot ends have the same orifice diameter.

[0035] By adopting the above technical solution, different hot ends can be detachably connected to the extruder. Different materials can be printed by replacing different hot ends, which can meet the different needs of the multidimensional printing process without replacing the entire multidimensional printing component, thus helping to reduce the cost of multidimensional printing.

[0036] In one embodiment of this application, at least one of the feed channel and the discharge channel is a straight channel.

[0037] By adopting the above technical solution, the feeding channel and / or discharging channel are set as straight channels, so that the material is less likely to get blocked when it moves in the feeding channel and / or discharging channel.

[0038] In one embodiment of this application, the hot end includes a heating section and a nozzle connected in sequence, and the discharge channel includes a first channel formed in the heating section, the first channel communicating with the nozzle and the feed channel.

[0039] By adopting the above technical solution, the material can enter the first channel through the feeding channel and the nozzle through the first channel of the heating unit. At this time, the heating unit can heat the material in the first channel so that the material is at a preset temperature, and then the material is sprayed out through the nozzle.

[0040] In one embodiment of this application, the hot end further includes a heat dissipation section, the heat dissipation section, and the nozzle are connected in sequence, and the discharge channel further includes a second channel formed in the heat dissipation section, the second channel and the first channel are connected.

[0041] By adopting the above technical solution, the length of the second channel is S1, and the length of the first channel is S2. With at least two hot ends, when different materials are needed, the hot ends can be directly replaced. Only the material in the second channel is wasted, meaning the waste length generated by this application is S1, thus effectively reducing material waste. Furthermore, since various materials have different melting temperatures, if switching from a high-temperature material to a low-temperature material, such as from a material with a melting temperature of 250°C to a material with a melting temperature of 200°C, the existing tool head switching feeding method would cause the 250°C material to clog the same hot end. However, the hot end replacement method of this application avoids this problem, satisfying the requirements for simultaneous printing of multiple materials and temperatures, as well as printing with multiple hot end nozzle orifices simultaneously.

[0042] In one embodiment of this application, the heat dissipation part includes a heat dissipation frame and a heat dissipation body. The heat dissipation body is mounted on the heat dissipation frame, and the heat dissipation frame has a connection hole. The first end of the heating part is connected to the heat dissipation body, and the second end of the heating part passes through the connection hole and protrudes from the heat dissipation frame.

[0043] By adopting the above technical solution, a connection hole is formed in the heat dissipation frame, allowing the heating element to connect to the heat dissipation body through the connection hole, thus improving the ease of connection between the heating element and the heat dissipation body. Simultaneously, after the first end of the heating element is connected to the heat dissipation body, the second end of the heating element can pass through the connection hole and protrude from the heat dissipation frame, ensuring that the second end of the heating element can protrude from the heat dissipation body, facilitating the connection between the heating element and the nozzle. Furthermore, the connection hole also serves as a limiting and guiding element for the heating element, facilitating the alignment of the second channel and the first channel.

[0044] In one embodiment of this application, the heating element is detachably connected to the heat dissipation frame.

[0045] By adopting the above technical solution, the heating element is detachably connected to the heat dissipation frame, allowing for easy assembly and disassembly of the heating element relative to the heat dissipation element. This facilitates replacement of the heating element or heat dissipation element in case of malfunction. Furthermore, the heating element can be disassembled for cleaning the second channel of the heat dissipation element and the first channel of the heating element, making cleaning of these channels easier.

[0046] Accordingly, this application also provides a multi-dimensional printing component for printing the same material, comprising:

[0047] An extruder having a feed channel and an installation area;

[0048] The extruder has at least two hot ends, each hot end having a discharge channel with a different aperture in the discharge channel. The discharge channels of the different hot ends are used to accommodate the same material. Each hot end is provided with a mating part adapted to the mounting area, and the mounting area is detachably connected to the at least two mating parts, so that the feed channel of the extruder is alternately connected to the discharge channels of the at least two hot ends, thereby enabling the extruder to convey the same material to the discharge channels of the hot ends with different apertures.

[0049] By adopting the above technical solution, the mating parts of different hot ends can be detachably connected to the installation area of ​​the extruder, and the orifice diameters of the discharge channels of different hot ends are different. Therefore, by replacing the hot ends connected to the extruder, the discharge orifice diameter of the multi-dimensional printing component can be changed to meet the different requirements for discharge orifice diameter during multi-dimensional printing, without replacing the entire multi-dimensional printing component, which helps to reduce the cost of multi-dimensional printing. In other words, to meet printing requirements, the same material can be contained in hot ends with different orifice diameters to meet the conditions of printing with multiple hot end nozzles simultaneously.

[0050] Accordingly, this application also provides a hot end, which has a discharge channel for containing material. The hot end is provided with a mating part that is adapted to the installation area of ​​the extruder. The mating parts of different hot ends can be detachably connected to the installation area so that the feed channel of the extruder is connected to the discharge channel of the hot end, thereby enabling the extruder to transport material into the discharge channel of the hot end.

[0051] By adopting the above technical solution, the mating parts of different hot ends can be detachably connected to the installation area of ​​the extruder. Different hot ends can meet different needs; for example, different hot ends can accommodate the same material or the discharge channel diameters of different hot ends are different. Therefore, by replacing the hot ends connected to the extruder, different needs in the multidimensional printing process can be met. In other words, this application, by setting at least two different hot ends, and with the extruder detachably connected to at least two hot ends, allows the extruder's feed channel to communicate with the discharge channels of different hot ends. This means the extruder can be used with different hot ends to meet different needs in the multidimensional printing process without replacing the entire multidimensional printing assembly, thus reducing the cost of multidimensional printing.

[0052] In one embodiment of this application, the hot end includes a heating section and a nozzle connected in sequence, and the discharge channel includes a first channel formed in the heating section, the first channel communicating with the nozzle and the feed channel.

[0053] By adopting the above technical solution, the material can enter the first channel through the feeding channel and the nozzle through the first channel of the heating unit. At this time, the heating unit can heat the material in the first channel so that the material is at a preset temperature, and then the material is sprayed out through the nozzle.

[0054] Accordingly, this application also provides an extruder having a feed channel and an installation area. The installation area is adapted to a mating part at the hot end. The mating part is detachably connected to the installation area so that the feed channel of the extruder is connected to the discharge channel at the hot end, thereby enabling the extruder to transport material into the discharge channel at the hot end.

[0055] By adopting the above technical solution, the mating parts of different hot ends can be detachably connected to the installation area of ​​the extruder. Different hot ends can meet different needs, such as accommodating different materials or having different discharge channel diameters. Furthermore, by replacing the hot ends connected to the extruder, different needs in the multidimensional printing process can be met. In other words, by setting at least two different hot ends, and with the extruder detachably connected to at least two hot ends, the extruder's feed channel can communicate with the discharge channels of different hot ends. This means the extruder can be used with different hot ends to meet different needs in the multidimensional printing process without replacing the entire multidimensional printing assembly, thus reducing the cost of multidimensional printing.

[0056] In one embodiment of this application, the extruder includes a body and a connector. The connector is located in the mounting area and can switch between a first state and a second state. In the first state, the connector is fixedly connected to the hot end and the body. In the second state, the hot end can move relative to the body.

[0057] By adopting the above technical solution, by placing the connector in the first state, the hot end and the body can be fixedly connected, realizing the connection between the hot end and the extruder, and ensuring stable communication between the feed channel of the extruder and the discharge channel of the hot end; when a new hot end needs to be replaced, the connector is placed in the second state, at which time the current hot end can be moved relative to the body, that is, the current hot end can be removed from the extruder, and then the new hot end is placed in the installation area, and the connector is placed in the first state again, so that the new hot end and the extruder are fixedly connected.

[0058] Accordingly, this application also provides a multi-dimensional printing device, including the multi-dimensional printing components described above.

[0059] In one embodiment of this application, the multidimensional printing device further includes a mounting base, which is detachably mounted with at least two hot ends.

[0060] By adopting the above technical solution, the mounting base can be used to store the hot end. When it is necessary to replace the hot end connected to the extruder, the hot end connected to the extruder can be disassembled and installed on the mounting base. At the same time, the new hot end at the mounting base can be removed and connected to the extruder, thus completing the replacement of the hot end of the multi-dimensional printing component. It is simple and convenient. In addition, the mounting base plays a role in storing the hot end, which is convenient for storing unused hot ends.

[0061] In one embodiment of this application, the multidimensional printing apparatus further includes a moving component that can move between the mounting base and the extruder to alternately move different hot ends to the mounting area.

[0062] By adopting the above technical solution, the hot end can be moved between the mounting base and the extruder by the moving component, realizing the automatic movement of the hot end between the mounting base and the extruder without manual operation.

[0063] In one embodiment of this application, the hot end has a connection area adapted to the moving component, and the moving component is detachably connected to the connection areas of at least two hot ends respectively;

[0064] The multi-dimensional printing device also includes a sensor located in the connection area, which is used to detect the connection status between the moving component and the connection area.

[0065] By adopting the above technical solution, the connection area between the moving component and the hot end is detachably connected. When the hot end needs to be moved, the connection area between the moving component and the hot end can be connected together. When the hot end moves to the mounting base or to the mounting area, i.e., when the hot end no longer needs to move, the moving component and the hot end can be disengaged. By setting a sensor at the connection area, the connection status between the moving component and the connection area can be detected, thus determining whether the moving component is connected to the connection area of ​​the hot end. When the hot end connected to the extruder is moved to the mounting base via the moving component, if the sensor detects that the moving component and the connection area are connected, the hot end can move relative to the extruder, so that the moving component can drive the hot end to move. If the sensor has not yet detected that the moving component and the connection area are connected, the hot end and the extruder can remain connected to prevent the hot end from falling off.

[0066] The beneficial effects of this application are:

[0067] Different hot-end fittings can be detachably connected to the extruder's mounting area. Different hot ends can meet different needs; for example, different hot ends can accommodate different materials or have different discharge channel diameters. Therefore, by replacing the hot ends connected to the extruder, different requirements in the multi-dimensional printing process can be met. In other words, this application, by setting at least two different hot ends, and with the extruder detachably connected to at least two hot ends, allows the extruder's feed channel to communicate with the discharge channels of different hot ends. This means the extruder can be used with different hot ends to meet different needs in the multi-dimensional printing process without replacing the entire multi-dimensional printing assembly, thus reducing the cost of multi-dimensional printing.

[0068] In existing technologies, the method of equipping multiple tool heads to meet the printing needs of different materials requires replacing a tool head each time a different material is printed, as each tool head includes an extruder and a hot end. In other words, each time a different material is printed, an extruder and a hot end need to be replaced. For example, if three materials need to be printed, three extruders and three hot ends need to be replaced. However, in this application, if three materials need to be printed, only one extruder and three hot ends are needed. This eliminates the need to replace the entire multi-dimensional printing assembly to meet the needs of using different materials, which helps to reduce the cost of multi-dimensional printing and the waste of materials, and allows the cost and material waste to be in a relatively balanced state.

[0087] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application. In addition, it should be understood that the specific embodiments described herein are only for illustration and explanation of this application and are not intended to limit this application. In this application, unless otherwise stated, directional terms such as "up," "down," "left," and "right" generally refer to up, down, left, and right in the actual use or working state of the device, specifically the drawing directions in the accompanying drawings.

[0088] In this application, unless otherwise expressly specified and limited, the terms "connected," "linked," "stacked," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two elements or the interaction between two elements. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0089] This application provides a multidimensional printing component and a multidimensional printing device, which are described in detail below. It should be noted that the order of description of the following embodiments is not intended to limit the preferred order of the embodiments of this application. Furthermore, in the following embodiments, the descriptions of each embodiment have their own emphasis; parts not described in detail in a certain embodiment can be referred to in the relevant descriptions of other embodiments.

[0090] According to the embodiments of the first aspect of this application, see [link / reference]. Figure 1 , Figure 2 and Figure 3 A multi-dimensional printing assembly is used to print different materials. The materials are categorized into different types based on their properties. These properties can include the material's color, melting temperature, and texture. The multi-dimensional printing assembly includes an extruder 1 and at least two hot ends 2. The extruder 1 has a feed channel and an installation area 11.

[0091] The hot end 2 has a discharge channel. Different hot ends 2 discharge channels are used to accommodate different materials. Each hot end 2 is provided with a mating part 21 that is adapted to the installation area 11. The installation area 11 is detachably connected to at least two mating parts 21, so that the feed channel of the extruder 1 is alternately connected to the discharge channels of at least two hot ends 2, thereby enabling the extruder 1 to transport different materials to the discharge channels of different hot ends 2.

[0092] According to the multi-dimensional printing component of this application embodiment, the mating parts 21 of different hot ends 2 can be detachably connected to the mounting area 11 of the extruder 1, and the discharge channels of different hot ends 2 are used to accommodate different materials. Therefore, by replacing the hot ends 2 connected to the extruder 1, the extruder 1 can transport different materials to the discharge channels of different hot ends 2, enabling the use of different materials. In other words, by providing at least two hot ends 2, and the extruder 1 being detachably connected to at least two hot ends 2, the feed channel of the extruder 1 can alternately communicate with the discharge channels of different hot ends 2, thereby enabling the transport of different materials to the discharge channels of different hot ends 2. This meets the needs of using different materials without replacing the entire multi-dimensional printing component, which helps reduce the cost of multi-dimensional printing. In existing technologies, where multiple tool heads are used to meet the printing needs of different materials, each tool head includes an extruder 1 and a hot end 2. Therefore, each time a different material is printed, a tool head must be replaced, meaning that an extruder 1 and a hot end 2 must be replaced each time a different material is printed. For example, if three materials need to be printed, then three extruders 1 and three hot ends 2 need to be replaced. However, in this application, if three materials need to be printed, only one extruder 1 and three hot ends 2 are needed. Thus, the need to use different materials can be met without replacing the entire multi-dimensional printing assembly, which helps to reduce the cost of multi-dimensional printing.

[0093] Understandably, the existing technology of using multiple tool heads to meet the needs of using different materials results in higher costs. If only one tool head is provided, when switching from material A to material B, the residual material A needs to be removed first, which will result in material waste.

[0094] In this application, as Figure 9 As shown, the hot end 2 includes a heat dissipation section 22 and a heating section 23 connected in sequence. The discharge channel includes a first channel formed in the heat dissipation section 22 and a second channel formed in the heating section 23, and the first channel and the second channel are connected. The length of the first channel is S1. The length of the second channel is S2. In the prior art, the method of switching the feed using a tool head requires discharging the remaining material in the hot end 2 each time, so the length of waste generated by this method is S = S1 + S2. In this application, the hot end 2 needs to be replaced separately when changing materials, and the material in the second channel of the hot end 2 is usually in a fluid state. Therefore, when replacing the hot end 2 separately in this application, it is only necessary to discharge the material in the first channel through the second channel. So, the length of waste generated each time a hot end 2 is replaced in this application is S1. Thus, the multidimensional printing component and multidimensional printing equipment of this application are beneficial to reducing the cost of multidimensional printing and the waste of materials, and make the cost and material waste relatively balanced.

[0095] It should be noted that, since the melting temperatures of various materials are different, if switching from a high-temperature material to a low-temperature material, such as switching from a material with a melting temperature of 250°C to a material with a melting temperature of 200°C, the existing tool head switching feeding method will cause the 250°C material to get stuck in the same hot end. However, the method of changing the hot end in this application can avoid this problem and meet the requirements of printing multiple materials and temperatures at the same time, as well as printing multiple hot end nozzle orifices at the same time.

[0096] In some examples, multidimensional printing is, for example, 3D printing.

[0097] In some embodiments, see Figure 1 , Figure 2 and Figure 3 The extruder 1 includes a body 13 and a connector 14. The connector 14 is located in the mounting area 11 and can switch between a first state and a second state. In the first state, the connector 14 is fixedly connected to the hot end 2 and the body 13. In the second state, the hot end 2 can move relative to the body 13.

[0098] It is understandable that by placing the connector 14 in the first state, the hot end 2 and the body 13 can be fixedly connected, thus achieving the connection between the hot end 2 and the extruder 1 and ensuring stable communication between the feed channel of the extruder 1 and the discharge channel of the hot end 2. When a new hot end 2 needs to be replaced, the connector 14 is placed in the second state. At this time, the current hot end 2 can be moved relative to the body 13, that is, the current hot end 2 can be removed from the extruder 1. Then, the new hot end 2 is placed in the installation area 11, and the connector 14 is placed in the first state again, so that the new hot end 2 and the extruder 1 are fixedly connected.

[0099] Understandably, placing the connector 14 in the mounting area 11 effectively utilizes the space of the mounting area 11, which is beneficial for simplifying the structure of the multi-dimensional printing component. Furthermore, since the hot end 2 is located in the mounting area 11, placing the connector 14 there as well allows for direct and fixed connection between the hot end 2 and the extruder 1 when the hot end 2 is in the mounting area 11. This improves the convenience of connecting the hot end 2 and the extruder 1, and further simplifies the structure of the connector 14.

[0100] In some examples, connector 14 is, for example, a magnetic connector, a snap-fit ​​connector, or an adhesive connector.

[0101] For example, when the connector 14 is a snap-fit ​​connector, the snap-fit ​​connector is fixedly connected to the body 13, and the snap-fit ​​connector can snap-fit ​​with the hot end 2. Specifically, the hot end 2 has a snap-fit ​​groove adapted to the snap-fit ​​connector. By engaging the snap-fit ​​groove of the hot end 2 with the snap-fit ​​connector, the snap-fit ​​connector and the hot end 2 can be snap-fitted together, thereby realizing the connection between the hot end 2 and the extruder 1. When disassembling the hot end 2, a force away from the snap-fit ​​connector is applied to the hot end 2 or a force away from the hot end 2 is applied to the snap-fit ​​connector, causing the snap-fit ​​connector and the hot end 2 to separate, and the hot end 2 can then move relative to the extruder 1.

[0102] In some embodiments, see Figure 1 , Figure 2 and Figure 3 The mating part 21 has a magnetic element 211, and the connector 14 includes an electromagnet 141. In a first state, the electromagnet 141 is energized and attracts the magnetic element 211. In a second state, the electromagnet 141 is de-energized and the magnetic element 211 can be detached from the electromagnet 141.

[0103] It is understandable that when the hot end 2 needs to be connected to the extruder 1, the connector 14 is in the first state, that is, the electromagnet 141 is energized. At this time, the electromagnet 141 generates a magnetic attraction force to attract the magnetic component 211 of the mating part 21, so that the magnetic component 211 and the electromagnet 141 are connected together, thereby realizing the connection between the hot end 2 and the extruder 1 through the connector 14. When the hot end 2 needs to be removed from the extruder 1, the connector 14 is in the second state, that is, the electromagnet 141 is de-energized. At this time, the electromagnet 141 loses its magnetic attraction force and no longer attracts the magnetic component 211 of the mating part 21, so that the mating part 21 can move relative to the electromagnet 141, that is, the hot end 2 can move relative to the extruder 1. In other words, this application can realize the connection between the hot end 2 and the extruder 1 through the cooperation of the electromagnet 141 and the magnetic component, which is simple in structure. At the same time, the connection between the hot end 2 and the extruder 1 can be controlled by controlling the energization state of the electromagnet 141, which is simple and convenient.

[0104] For details, please refer to Figure 1 , Figure 2 and Figure 3 The multidimensional printing component also includes a control component 5, which is connected to the electromagnet 141 and is used to control the electromagnet 141 to switch between a powered-on state and a powered-off state.

[0105] The control component 5 is connected to the main body 13, and the control component 5 and the installation area 11 are spaced apart.

[0106] It is understandable that the energization state of the electromagnet 141 can be controlled by the control component 5, and the connector 14 can be switched between the first and second states by the control component 5. At the same time, the control component 5 and the mounting area 11 are spaced apart to avoid the control component 5 occupying the space of the mounting area 11, to prevent the control component 5 from interfering with the hot end 2, and to ensure that the hot end 2 can be successfully installed in the mounting area 11.

[0107] In some embodiments, see Figure 2 , Figure 5 and Figure 6 The mating portion 21 has a mounting groove 212, and the magnetic component 211 is disposed within the mounting groove 212. The mounting groove 212 can limit the magnetic component 211, improving the installation stability of the magnetic component 211. Furthermore, by using the mounting groove 212 to install the magnetic component 211, at least a portion of the magnetic component 211 will be located within the mounting groove 212, which can effectively reduce the protrusion length of the magnetic component 211 from the mating portion 21, and help simplify the structure of the hot end 2.

[0108] In some examples, the side of the magnetic component 211 facing away from the inner bottom wall of the mounting groove 212 is flush with the opening of the mounting groove 212, which helps to improve the structural flatness of the hot end 2.

[0109] For details, please refer to Figure 2 , Figure 5 and Figure 6 The mating part 21 also has a notch 213 that communicates with the mounting groove 212.

[0110] Understandably, by providing a notch 213 that communicates with the mounting groove 212, the notch 213 can provide clearance space when installing the magnetic component 211, so that the magnetic component 211 can be installed in the mounting groove 212, thus improving the ease of installation of the magnetic component 211; when removing the magnetic component, external force can be applied to the magnetic component through the notch 213, so that the magnetic component can be detached from the mounting groove 212, thus improving the ease of removal of the magnetic component.

[0111] For example, when the robot arm is used to install or remove the magnetic component 211, the notch 213 can provide clearance for the robot arm, so that the robot arm can smoothly install the magnetic component 211 into or remove it from the mounting groove 212.

[0112] In some embodiments, see Figure 10 The connector 14 includes a first snap-fit ​​structure 142 and a second snap-fit ​​structure 143 formed on the hot end 2. In the first state, the first snap-fit ​​structure 142 and the second snap-fit ​​structure 143 are snapped together to fix the hot end 2 and the body 13.

[0113] Understandably, when it is necessary to connect the hot end 2 and the body 13, the first snap-fit ​​structure 142 and the second snap-fit ​​structure 143 are engaged to connect the hot end 2 and the body 13 together, thereby fixing the hot end 2 and the extruder 1 together and achieving the snap-fit ​​connection between the hot end 2 and the extruder 1. When it is necessary to disassemble the hot end 2, the first snap-fit ​​structure 142 and the second snap-fit ​​structure 143 are disengaged and contacted, and the hot end 2 can move relative to the body 13, thereby achieving the disassembly of the hot end 2. This allows the hot end 2 to be detachably connected to the extruder 1, and the disassembly and assembly of the hot end 2 is convenient.

[0114] In some examples, one of the first snap-fit ​​structure 142 and the second snap-fit ​​structure 143 is a snap-fit ​​post, and the other of the first snap-fit ​​structure 142 and the second snap-fit ​​structure 143 is a snap-fit ​​hole.

[0115] In some embodiments, see Figure 1 , Figure 2 and Figure 3 The extruder 1 is provided with a connecting end 12 for connection with the hot end 2. The mounting area 11 includes a mounting space 111 formed in the connecting end 12 of the extruder 1. The shape of the mating part 21 is adapted to the mounting space 111. The adaptation may be that the shape and / or size of the mating part 21 matches the mounting space 111. The mating part 21 is accommodated within the mounting space 111.

[0116] It is understandable that by forming an installation space 111 at the connection end 12 of the extruder 1, the hot end 2, whose shape is adapted to the installation space 111, can be set in the installation space 111, thus ensuring that the hot end 2 can be connected to the extruder 1.

[0117] It is understandable that the shapes of the mating parts 21 of different hot ends 2 are all adapted to the installation space 111, and different hot ends 2 can be alternately set in the installation space 111, that is, different hot ends 2 can be alternately connected to the extruder 1.

[0118] For details, please refer to Figure 1 , Figure 2 and Figure 3 The connecting end 12 includes a first connecting part 121 and a second connecting part 122 connected in sequence. The first connecting part 121 extends along a first direction, and the second connecting part 122 extends along a second direction. The first direction and the second direction intersect, and an installation space 111 is formed between the first connecting part 121 and the second connecting part 122.

[0119] It is understood that the first end of the first connecting part 121 is connected to the first end of the second connecting part 122, the second end of the first connecting part 121 extends along the first direction, the second end of the second connecting part 122 extends along the second direction, and there is an angle greater than 0° between the extension direction of the second end of the first connecting part 121 and the extension direction of the second end of the second connecting part 122. Then, an installation space 111 will be formed between the second end of the first connecting part 121 and the second end of the second connecting part 122, so that the hot end 2 can be accommodated in the installation space 111.

[0120] It is understood that the shape of at least one of the first connecting portion 121 and the second connecting portion 122 is adapted to the shape of the mating portion 21 of the hot end 2, ensuring that the hot end 2 can be adapted to the connecting end 12 of the extruder 1, thereby realizing the connection between the hot end 2 and the extruder 1. In some examples, the shape of the side of the first connecting portion 121 facing the hot end 2 is adapted to the shape of the mating portion 21, so that the mating portion 21 of the hot end 2 can be matched and connected with the first connecting portion 121. For example, the feed channel of the extruder 1 is formed in the first connecting portion 121, and when the mating portion 21 is mated with the first connecting portion 121, the discharge channel of the hot end 2 and the feed channel of the extruder 1 are connected.

[0121] In some examples, the mounting area 11 may also refer to the mounting surface formed on the extruder 1, the shape of which is adapted to the shape of the mating part 21, so that the mating part 21 can cooperate with the mounting surface to realize the connection between the hot end 2 and the extruder 1.

[0122] In some embodiments, see Figure 3 The multidimensional printing component also includes at least one positioning element 3, which is located in the mounting area 11 and is used to position the mating part 21 so that the mating part 21 and the mounting area 11 cooperate.

[0123] It is understandable that when the hot end 2 is connected to the mounting area 11, the positioning member 3 can position the mating part 21 of the hot end 2, so that the mating part 21 of the hot end 2 can smoothly cooperate with the mounting area 11 of the extruder 1, and realize the connection and cooperation between the hot end 2 and the extruder 1.

[0124] For details, please refer to Figure 3 The positioning element 3 is connected to the extruder 1. The end of the positioning element 3 facing away from the extruder 1 has a first guide surface 31. The first guide surface 31 is used to guide the mating part 21 and the positioning element 3 to cooperate.

[0125] It is understandable that when the hot end 2 is connected to the extruder 1, the mating part 21 of the hot end 2 will first contact the first guide surface 31 of the positioning member 3. The first guide surface 31 can guide the mating part 21 to cooperate with the positioning member 3 so that the positioning member 3 can position the mating part 21 of the hot end 2.

[0126] In some examples, the number of positioning elements 3 is at least two, and at least two positioning elements 3 are arranged around the electromagnet 141 to improve the structural compactness of the multidimensional printed assembly.

[0127] In some examples, the positioning element 3 is, for example, a positioning pin or a positioning plate or any other suitable structural element with positioning function.

[0128] For details, please refer to Figure 2 and Figure 3 The mating part 21 has a positioning hole 214, and the positioning member 3 can be inserted into the positioning hole 214 to position the mating part 21.

[0129] It is understandable that by forming a positioning hole 214 in the mating part 21 that is compatible with the positioning member 3, the positioning member 3 can be inserted into the mating part 21 to achieve positioning of the mating part 21.

[0130] Specifically, a second guide surface is formed at the opening of the positioning hole 214, which is used to guide the positioning member 3 into the positioning hole 214.

[0131] It is understandable that by setting a second guide surface at the opening of the positioning hole 214, when the hot end 2 is installed in the installation area 11, the second guide surface can guide the positioning member 3, guide the positioning member 3 to be inserted into the positioning hole 214, so that the positioning member 3 can smoothly and quickly cooperate with the positioning hole 214 to achieve the positioning of the hot end 2.

[0132] In some embodiments, the nozzles 24 at different hot ends 2 have different diameters.

[0133] It is understandable that different hot ends 2 can be detachably connected to the extruder 1. By replacing different hot ends 2, the nozzle 24 diameter of the multidimensional printing component can be changed, which can meet the different needs of the multidimensional printing process without replacing the entire multidimensional printing component, thus helping to reduce the cost of multidimensional printing.

[0134] In some embodiments, at least one of the feed channel and the discharge channel is a straight channel.

[0135] It is understandable that setting the feed channel and / or discharge channel as a straight channel makes it less likely for the material to become blocked when moving within the feed channel and / or discharge channel.

[0136] Understandably, a straight channel refers to a channel that extends in a straight line without any bends.

[0137] In some embodiments, see Figure 4 , Figure 5 and Figure 7 The hot end 2 includes a heating section 23 and a nozzle 24 connected in sequence, and the discharge channel includes a first channel formed in the heating section 23, which connects the nozzle 24 and the feed channel.

[0138] It is understandable that the first channel of the heating unit 23 connects the feeding channel and the nozzle 24, so that the material can enter the first channel through the feeding channel. At this time, the heating unit 23 can heat the material in the first channel so that the material is at a preset temperature, and then the material is sprayed out through the nozzle 24.

[0139] In some embodiments, see Figure 4 , Figure 5 and Figure 7 The hot end 2 also includes a heat dissipation section 22, and the heat dissipation section 22, the heating section 23, and the nozzle 24 are connected in sequence. The discharge channel also includes a second channel formed in the heat dissipation section 22 that communicates with the first channel. Figure 9 As shown, the length of the second channel is S1. The length of the first channel is S2.

[0140] It is understandable that the extruder 1 conveys the material to the second channel, and then the material is conveyed to the first channel. At this time, the heating unit 23 can heat the material to bring it to a preset temperature so that the nozzle 24 can spray the material out.

[0141] Understandably, existing technologies reduce costs by using a single tool head to switch feeds. However, this requires clearing residual material from the hot end 2 during switching, resulting in material waste in both the first and second channels, with the length of wasted material being S1 + S2 = S. This application, by providing at least two hot ends 2, allows for direct replacement of these ends when different materials are needed. This eliminates material waste only in the second channel, resulting in a waste length of S1, effectively reducing waste. Furthermore, since different materials have different melting temperatures, switching from a high-temperature material to a low-temperature material (e.g., from a material with a melting temperature of 250°C to one with a melting temperature of 200°C) using a single tool head in existing technologies can cause the 250°C material to become clogged in the same hot end. This application's hot end replacement method avoids this problem, enabling simultaneous printing of multiple materials at multiple temperatures and printing with multiple hot end nozzle diameters.

[0142] In some embodiments, see Figure 1 , Figure 4 and Figure 5 The heat dissipation part 22 includes a heat dissipation frame 221 and a heat dissipation body 222. The heat dissipation body 222 is mounted on the heat dissipation frame 221. The heat dissipation frame 221 has a connection hole 2211. The first end of the heating part 23 is connected to the heat dissipation body 222. The second end of the heating part 23 passes through the connection hole 2211 and protrudes from the heat dissipation frame 221.

[0143] Understandably, by forming a connecting hole 2211 at the heat dissipation frame 221, the heating element 23 can be connected to the heat dissipation body 222 through the connecting hole 2211, improving the ease of connection between the heating element 23 and the heat dissipation body 22. Simultaneously, after the first end of the heating element 23 is connected to the heat dissipation body 222, the second end of the heating element 23 can pass through the connecting hole 2211 and protrude from the heat dissipation frame 221, ensuring that the second end of the heating element 23 can protrude from the heat dissipation body 22, facilitating the connection between the heating element 23 and the nozzle 24. Furthermore, the connecting hole 2211 also serves as a limiting and guiding element for the heating element 23, facilitating the alignment of the second channel and the first channel.

[0144] Specifically, the heating element 23 is detachably connected to the heat dissipation frame 221.

[0145] Understandably, by detachably connecting the heating element 23 to the heat dissipation frame 221, the heating element 23 can be disassembled and assembled relative to the heat dissipation element 22, thereby facilitating the replacement of the heating element 23 or the heat dissipation element 22 in case of a malfunction. Simultaneously, when cleaning the second channel of the heat dissipation element 22 and the first channel of the heating element 23, the heating element 23 can be disassembled, facilitating the cleaning of the second and first channels.

[0146] In some examples, the heating element 23 is detachably connected to the heat dissipation frame 221 by means of snap-fit, magnetic attraction, adhesive or other methods.

[0147] According to an embodiment of the second aspect of this application, this application also provides a multi-dimensional printing assembly for printing the same material. This second aspect embodiment differs from the first aspect embodiment in the following ways: it has at least two hot ends 2, each hot end 2 forming a discharge channel with a different aperture in its discharge channel. The discharge channels of different hot ends 2 are used to accommodate the same material. Each hot end 2 is provided with a mating part 21 adapted to the mounting area 11, and the mounting area 11 is detachably connected to at least two mating parts 21, so that the feed channel of the extruder 1 alternately communicates with the discharge channels of the at least two hot ends 2. This allows the extruder 1 to convey the same material into the discharge channels of the hot ends 2 with different apertures. In other words, to meet printing requirements, the same material can be accommodated in hot ends with different apertures to satisfy the condition of printing with multiple hot end nozzle apertures simultaneously.

[0148] It is understood that the mating parts 21 of different hot ends 2 can be detachably connected to the mounting area 11 of the extruder 1, and the discharge channels of different hot ends 2 have different apertures. Therefore, by replacing the hot ends 2 connected to the extruder 1, the discharge aperture of the multi-dimensional printing component can be changed to meet the different requirements for the discharge aperture during the multi-dimensional printing process. There is no need to replace the entire multi-dimensional printing component, which helps to reduce the cost of multi-dimensional printing.

[0149] According to an embodiment of the third aspect of this application, this application also provides a hot end 2, which has a discharge channel for receiving materials. The hot end 2 is provided with a mating part 21, which is adapted to the mounting area 11 of the extruder 1. The mating parts 21 of different hot ends 2 can be detachably connected to the mounting area 11 so that the feed channel of the extruder 1 is connected to the discharge channel of the hot end 2, thereby enabling the extruder 1 to transport materials into the discharge channel of the hot end 2.

[0150] According to the embodiments of this application, the mating parts 21 of different hot ends 2 can be detachably connected to the mounting area 11 of the extruder 1. Different hot ends 2 can meet different needs, such as accommodating different materials or having different discharge channel diameters. Therefore, by replacing the hot ends 2 connected to the extruder 1, different needs in the multidimensional printing process can be met. In other words, by setting at least two different hot ends 2, and detachably connecting the extruder 1 to at least two hot ends, the feed channel of the extruder 1 can communicate with the discharge channels of different hot ends 2. This means the extruder 1 can be used with different hot ends 2 to meet different needs in the multidimensional printing process without replacing the entire multidimensional printing assembly, thus reducing the cost of multidimensional printing.

[0151] For details, please refer to Figure 4 , Figure 5 and Figure 7 The hot end 2 includes a heating section 23 and a nozzle 24 connected in sequence, and the discharge channel includes a first channel formed in the heating section 23, which connects the nozzle 24 and the feed channel.

[0152] It is understandable that the first channel of the heating unit 23 connects the feeding channel and the nozzle 24, so that the material can enter the first channel through the feeding channel. At this time, the heating unit 23 can heat the material in the first channel so that the material is at a preset temperature, and then the material is sprayed out through the nozzle 24.

[0153] According to an embodiment of the fourth aspect of this application, this application also provides an extruder 1. The extruder 1 has a feed channel and an installation area 11 is provided on the extruder 1. The installation area 11 is adapted to mate with a mating part 21 of the hot end 2. The mating part 21 is detachably connected to the installation area 11 so that the feed channel of the extruder 1 communicates with the discharge channel of the hot end 2, thereby enabling the extruder 1 to convey material into the discharge channel of the hot end 2.

[0154] According to the extruder of this application embodiment, the mating parts 21 of different hot ends 2 can be detachably connected to the mounting area 11 of the extruder 1. Different hot ends 2 can meet different needs, such as different hot ends 2 can accommodate different materials, and different hot ends 2 have different discharge channel diameters. Therefore, by replacing the hot ends 2 connected to the extruder 1, different needs in the multidimensional printing process can be met. In other words, by setting at least two different hot ends 2, and the extruder 1 is detachably connected to at least two hot ends, the feed channel of the extruder 1 can communicate with the discharge channels of different hot ends 2. That is, the extruder 1 can be used with different hot ends 2 to meet different needs in the multidimensional printing process without replacing the entire multidimensional printing assembly, which helps to reduce the cost of multidimensional printing.

[0155] For details, please refer to Figure 1 , Figure 2 and Figure 3 The extruder 1 includes a body 13 and a connector 14. The connector 14 is located in the mounting area 11 and can switch between a first state and a second state. In the first state, the connector 14 is fixedly connected to the hot end 2 and the body 13. In the second state, the hot end 2 can move relative to the body 13.

[0156] It is understandable that by placing the connector 14 in the first state, the hot end 2 and the body 13 can be fixedly connected, thus achieving the connection between the hot end 2 and the extruder 1 and ensuring stable communication between the feed channel of the extruder 1 and the discharge channel of the hot end 2. When a new hot end 2 needs to be replaced, the connector 14 is placed in the second state. At this time, the current hot end 2 can be moved relative to the body 13, that is, the current hot end 2 can be removed from the extruder 1. Then, the new hot end 2 is placed in the installation area 11, and the connector 14 is placed in the first state again, so that the new hot end 2 and the extruder 1 are fixedly connected.

[0157] Understandably, placing the connector 14 in the mounting area 11 effectively utilizes the space of the mounting area 11, which is beneficial for simplifying the structure of the multi-dimensional printing component. Furthermore, since the hot end 2 is located in the mounting area 11, placing the connector 14 there as well allows for direct and fixed connection between the hot end 2 and the extruder 1 when the hot end 2 is in the mounting area 11. This improves the convenience of connecting the hot end 2 and the extruder 1, and further simplifies the structure of the connector 14.

[0158] In some examples, connector 14 is, for example, a magnetic connector, a snap-fit ​​connector, or an adhesive connector.

[0159] For example, when the connector 14 is a snap-fit ​​connector, the snap-fit ​​connector is fixedly connected to the body 13, and the snap-fit ​​connector can snap-fit ​​with the hot end 2. Specifically, the hot end 2 has a snap-fit ​​groove adapted to the snap-fit ​​connector. By engaging the snap-fit ​​groove of the hot end 2 with the snap-fit ​​connector, the snap-fit ​​connector and the hot end 2 can be snap-fitted together, thereby realizing the connection between the hot end 2 and the extruder 1. When disassembling the hot end 2, a force away from the snap-fit ​​connector is applied to the hot end 2 or a force away from the hot end 2 is applied to the snap-fit ​​connector, causing the snap-fit ​​connector and the hot end 2 to separate, and the hot end 2 can then move relative to the extruder 1.

[0160] According to an embodiment of the fifth aspect of this application, the multi-dimensional printing apparatus includes the multi-dimensional printing components described above.

[0161] According to the multi-dimensional printing device of this application embodiment, the mating parts 21 of different hot ends 2 can be detachably connected to the mounting area 11 of the extruder 1, and the discharge channels of different hot ends 2 are used to accommodate different materials. Therefore, by replacing the hot ends 2 connected to the extruder 1, the extruder 1 can transport different materials to the discharge channels of different hot ends 2, thus enabling the use of different materials. In other words, this application, by providing at least two hot ends 2 and allowing the extruder 1 to be detachably connected to at least two hot ends 2 respectively, allows the feed channel of the extruder 1 to alternately communicate with the discharge channels of different hot ends 2, thereby enabling the transport of different materials to the discharge channels of different hot ends 2. In existing technologies, which use multiple tool heads to meet the printing needs of different materials, each tool head includes an extruder and a hot end. Therefore, each time a different material is printed, a tool head must be replaced, meaning that an extruder and a hot end must be replaced each time a different material is printed. For example, if three materials need to be printed, three extruders and three hot ends need to be replaced. However, in this application, if three materials need to be printed, only one extruder and three hot ends are needed. This eliminates the need to replace the entire multi-dimensional printing assembly to meet the needs of using different materials, which helps to reduce the cost of multi-dimensional printing equipment.

[0162] In some embodiments, see Figure 8The multidimensional printing device also includes a mounting base 4, which is detachably mounted with at least two hot ends 2.

[0163] Understandably, the mounting base 4 can be used to store the hot end 2. When it is necessary to replace the hot end 2 connected to the extruder 1, the hot end 2 connected to the extruder 1 can be removed and installed on the mounting base 4. At the same time, the new hot end 2 at the mounting base 4 can be removed and connected to the extruder 1, thus completing the replacement of the hot end 2 of the multi-dimensional printing component. It is simple and convenient. In addition, the mounting base 4 serves to store the hot end 2, making it convenient to store unused hot ends 2.

[0164] In some embodiments, the multidimensional printing apparatus further includes a moving component that can move between the mounting base 4 and the extruder 1 to alternately move different hot ends 2 to the mounting area 11.

[0165] It is understandable that the hot end 2 can be moved between the mounting base 4 and the extruder 1 by the moving component, so as to realize the automatic movement of the hot end 2 between the mounting base 4 and the extruder 1 without manual operation.

[0166] For example, the moving component is a robotic arm or a three-axis drive device equipped with grippers.

[0167] In some embodiments, the hot end 2 has a connection area 25 adapted to the moving component, and the moving component is detachably connected to the connection areas 25 of at least two hot ends 2 respectively.

[0168] The multi-dimensional printing device also includes a sensor 6, which is located in the connection area 25 and is used to detect the connection status between the moving component and the connection area 25.

[0169] It is understood that the moving component is detachably connected to the connection area 25 of the hot end 2. When the hot end 2 needs to be moved, the moving component and the connection area 25 of the hot end 2 can be connected together. When the hot end 2 is moved to the mounting base 4 or to the mounting area 11, that is, when the hot end 2 no longer needs to be moved, the moving component and the hot end 2 can be detached.

[0170] By setting a sensor 6 at the connection area 25, the connection status between the moving component and the connection area 25 can be detected by the sensor 6, which can determine whether the moving component is connected to the connection area 25 of the hot end 2. When the hot end 2 connected to the extruder 1 is moved to the mounting base 4 by the moving component, if the sensor 6 detects that the moving component and the connection area 25 are connected, the hot end 2 can be moved relative to the extruder 1 so that the moving component can drive the hot end 2 to move. If the sensor 6 has not yet detected that the moving component and the connection area 25 are connected, the hot end 2 and the extruder 1 can be kept connected to prevent the hot end 2 from falling off.

[0171] In some examples, the sensor 6 is, for example, a pressure sensor 6 or an infrared sensor 6.

[0172] In some examples, sensor 6 may include a controller that can determine whether the moving component is connected to connection area 25 based on the detection data. Alternatively, a separate controller may be provided independently of sensor 6, electrically connected to sensor 6, so that the controller can determine whether the moving component is connected to connection area 25 based on the detection data from sensor 6.

[0173] The technical solutions of the embodiments of this application will be described below with reference to specific examples.

[0174] Example 1:

[0175] A multidimensional printing device includes an extruder 1 and at least two different hot ends 2. The extruder 1 has a feed channel and an installation area 11. The hot ends 2 have a discharge channel for receiving material. The hot ends 2 are provided with a mating part 21 adapted to the installation area 11. The mating part 21 is detachably connected to the installation area 11 so that the feed channel of the extruder 1 communicates with the discharge channel of the hot ends 2, thereby enabling the extruder 1 to convey material into the discharge channel of the hot ends 2.

[0176] When a multi-dimensional printing device needs to print different materials, since different hot ends 2 can accommodate different materials, by replacing the hot end 2 connected to the extruder 1, the extruder 1 can transport different materials to the discharge channels of different hot ends 2, thus enabling the use of different materials.

[0177] When a multi-dimensional printing device needs to print materials of different sizes, the orifice diameter of the discharge channel of different hot ends 2 is different. By replacing the hot end 2 connected to the extruder 1, the discharge orifice diameter of the multi-dimensional printing component can be changed to meet the different requirements for discharge orifice diameter during the multi-dimensional printing process. There is no need to replace the entire multi-dimensional printing component, which helps to reduce the cost of multi-dimensional printing.

[0178] Example 2:

[0179] A multidimensional printing assembly includes an extruder 1 and at least two different hot ends 2, the hot ends 2 being magnetically engaged with the extruder 1.

[0180] Specifically, the hot end 2 is equipped with a magnetic component 211, and the extruder 1 is equipped with an electromagnet 141. The electromagnet 141 can switch between an energized and de-energized state. In the energized state, the electromagnet 141 generates a magnetic attraction force to attract the magnetic component 211 of the mating part 21, thus connecting the magnetic component 211 and the electromagnet 141 together. This achieves the connection between the hot end 2 and the extruder 1 via the connector 14. In the de-energized state, the electromagnet 141 loses its magnetic attraction force and no longer attracts the magnetic component 211 of the mating part 21, allowing the mating part 21 to move relative to the electromagnet 141, i.e., the hot end 2 can move relative to the extruder 1. In other words, this application achieves the connection between the hot end 2 and the extruder 1 through the cooperation of the electromagnet 141 and the magnetic component, which is simple in structure. At the same time, the connection between the hot end 2 and the extruder 1 can be controlled by controlling the energized state of the electromagnet 141, which is simple and convenient.

[0181] Example 3:

[0182] The printing assembly includes an extruder 1 and at least two different hot ends 2, which are snap-fitted into the extruder 1.

[0183] Specifically, the extruder 1 is provided with a first snap-fit ​​structure 142, and the hot end 2 is provided with a second snap-fit ​​structure 143. The first snap-fit ​​structure 142 and the second snap-fit ​​structure 143 are engaged in a snap-fit ​​connection. When it is necessary to connect the hot end 2 and the body 13, the first snap-fit ​​structure 142 and the second snap-fit ​​structure 143 are engaged in a snap-fit ​​connection, thereby fixing the hot end 2 and the body 13 together and realizing the snap-fit ​​connection between the hot end 2 and the extruder 1. When it is necessary to disassemble the hot end 2, the first snap-fit ​​structure 142 and the second snap-fit ​​structure 143 are disengaged and contact each other, allowing the hot end 2 to move relative to the body 13, thereby realizing the disassembly of the hot end 2. This makes the hot end 2 detachably connected to the extruder 1, and the disassembly and assembly of the hot end 2 are convenient.

Therefore, the content of this specification should not be construed as a limitation of this application.
