[0032] 3D printer
[0033] like Figure 1 As shown, the 3D printer has a printing platform 14. The printing platform 14 theoretically defines an xy-plane, which is defined by the x-axis and y-axis. The x-axis, y-axis, and z-axis are perpendicular to each other, as shown... Figure 1 As shown. The term "movement along an axis," such as along the x-axis, y-axis, or z-axis, indicates movement parallel to or along the same straight line as that axis. In this document, the orientation specified by the x-axis, y-axis, or z-axis is for convenience of discussion only and does not constitute any limitation on the orientation. Of course, those skilled in the art will appreciate that the printing platform 14 can be connected to an x-axis, y-axis, or z-axis motion module, and this is not limited herein. Additionally, the printing platform 14 has a heating function and can be a single piece of material or composed of multiple layers of material connected in a detachable or non-detachable manner. The printing platform 14 of the 3D printer can be used to place the material to be printed, the substrate, etc. The printing platform 14 provides a work surface that is as flat as possible. The printing platform 14 defines the range of motion of the print head.
[0034] like Figure 1 As shown, the 3D printer may include x-axis, y-axis, and z-axis motion modules 15, a printing platform 14, and drive motors corresponding to the x-axis, y-axis, and z-axis motion modules. For example, the x-axis motion module 15 (generally with or including a drive motor or actuator) may be operatively connected to the second printing assembly 13, controlling the movement of the second printing assembly 13 along the x-axis. The x-axis motion module 15 may be operatively connected to the y-axis motion module, controlling the movement of the second printing assembly 13 along the y-axis. The z-axis motion module (generally with or including a drive motor or actuator) may be connected to the printing platform 14, controlling the movement of the printing platform 14 along the z-axis. However, the 3D printer of this application is not limited to this configuration.
[0035] The 3D printer 1 can also be equipped with a controller, which may include a main control chip or other units with control functions. The controller can control the movement of the x-axis, y-axis, and z-axis motion modules 15.
[0036] Specifically, such as Figure 1 As shown, the 3D printer 1 includes: a printing assembly, which includes a plurality of first printing components 11 with hot ends, and a second printing component 13, the second printing component 13 being configured to engage one of the plurality of first printing components 11 and drive the first printing component 11 to a printing area for material extrusion; a printing platform 14; and an x, y, and z-axis motion module 15 configured to cause the second printing component 13 and the printing platform 14 to move relative to each other in the x, y, and z-axis directions. The second printing component 13 includes a second connecting portion 131 that engages with the first printing component 11 and a second interface 13a that transmits electrical and / or signal information to the first printing component 11, such as... Figure 2 As shown.
[0037] The first printing component 11 is provided with a hot end or nozzle for extruding material. A first printing component storage area 12 is used to store the first printing component 11 and can be mounted on the frame of the 3D printer 1. The first printing component storage area 12 includes a holder 121 for suspending or fixing the first printing component 11. A second printing component 13 is configured to move to the first printing component storage area 12, engage one of the plurality of first printing components 11, and drive the first printing component 11 to the printing area for material extrusion. A printing platform 14 is disposed below the first printing component 11 and the second printing component 13. A motion module 15 is configured to cause the second printing component 13 and the printing platform 14 to move relative to each other in the x, y, and z axis directions. The motion module 15 may include x, y, and z axis motion modules 15. The second printing component 13 is controlled by the x and y axis motion modules 15, and the printing platform 14 is controlled by the z axis motion module 15. Alternatively, the second printing component 13 can be controlled by the x, y, and z axis motion modules 15.
[0038] like Figure 1 As shown, the first printing component 11 and the second printing component 13 can form the print head of a 3D printer. Multiple first printing components 11 can be connected to materials of different colors, and different colored materials can be deposited during the 3D printing process by changing the first printing components 11 connected to materials of different colors.
[0039] like Figure 2 As shown, the first printing component 11 includes a first printing component housing 111, a first connecting portion 112 that engages with the second connecting portion, and a first interface 11a that transmits electrical signals and / or signals to the second interface.
[0040] like Figure 2As shown, the second printing assembly 13 includes a second printing assembly housing 130 and a fan assembly 132, the fan assembly being configured to reduce the temperature of the printed model when the first printing assembly 11 and the second printing assembly 13 are engaged. Figure 2 As shown, the second printing assembly 13 also includes an air duct 133. The fan assembly 132 can be a cooling unit such as a fan or blower that can reduce the temperature of the printed model and enable it to cure quickly. The air duct 133 faces the printed model to guide cool air towards it. The air duct 133 may include an air inlet and an air outlet, with the air outlet facing the printed model itself.
[0041] like Figure 1-2 As shown, the first printing component 11 may include a cable m connected to a power source. The first printing component 11 includes a first interface 11a, and the second printing component 13 includes a second interface 13a. The first interface 11a and the second interface 13a are configured to transmit power or control signals. When the first printing component 11 and the second printing component 13 are engaged, the first interface 11a and the second interface 13a are connected to provide power or control signals. Therefore, the first printing component 11 supplies power to the second printing component 13 through the first interface 11a and the second interface 13a to start the fan assembly 132; and / or the first printing component 11 transmits control signals to the second printing component 13 through the first interface 11a and the second interface 13a to control the speed of the fan assembly 132. With this configuration, there is no need to provide a separate cable for the second printing component 13, which simplifies the printhead structure and facilitates high-speed printing.

The foregoing description is not intended to be exhaustive, nor is it intended to limit the invention to the precise steps and / or forms disclosed; clearly, many modifications and variations can be made in light of the teachings above. The scope of the invention and all its equivalents are intended to be defined by the appended claims.
