[0060] Example
[0061] Figure 1 Schematic diagram of the structure of a 3D printer 1000 in one embodiment of the present application; Figure 2 for Figure 1 A schematic diagram of the assembly state of the 3D printer base 100 and the gantry 200 in the illustrated embodiment; Figure 3 for Figure 1 A perspective view of the 3D printer base 100 in the illustrated embodiment.
[0062] See also Figure 1 , an embodiment of the present application provides a 3D printer 1000 , including a 3D printer base 100 .
[0063] For ease of understanding, the embodiments of the present application introduce a first direction Y, a second direction X, and a third direction Z for description. The first direction Y, the second direction X, and the third direction Z are three non-parallel directions in a spatial coordinate system. In subsequent embodiments, the first direction Y, the second direction X, and the third direction Z are described as three mutually perpendicular reference directions in a three-dimensional Cartesian coordinate system. The directions shown in the embodiments of the present application are used to help understand the relative positional relationship of the various components, but do not limit their specific directions.
[0064] In some embodiments, as Figure 1 and Figure 2 As shown, the 3D printer 1000 further includes a gantry 200 connected to the 3D printer base 100. A nozzle assembly 300 is mounted on the gantry 200 and is mounted on the gantry 200 via an X-axis drive mechanism. A molding platform 101 is mounted on the 3D printer base 100 and is used to support and mold the consumable material extruded by the nozzle assembly 300. A Y-axis drive mechanism may be provided within the 3D printer base 100 to drive the molding platform 101 in a first direction Y. The 3D printer base 100 may also include other functional components such as a circuit board and a power adapter.
[0065] In some embodiments, as Figure 2 As shown, the gantry 200 includes a bottom beam 201 and two columns 202 . The two ends of the bottom beam 201 are respectively connected to one end of the two columns 202 . The bottom beam 201 and the columns 202 are integrally arranged to improve the overall rigidity of the gantry 200 .
[0066] In some embodiments, as Figure 3As shown, the 3D printer base 100 includes a top shell 10 and a bottom shell 20. The bottom shell 20 includes a first shell 21, a second shell 22, a third shell 23 and a fourth shell 24. The third shell 23 is recessed inwardly toward the top shell 10 to form a first avoidance groove 23a. The fourth shell 24 is recessed inwardly toward the top shell 10 to form a second avoidance groove 24a. The first avoidance groove 23a is connected to the second avoidance groove 24a to form an avoidance channel. Figure 2 As shown, the bottom beam 201 passes through the avoidance channel. In this way, the bottom beam 201 is installed using the space on the side of the 3D printer base 100 away from the building platform 101, which is conducive to reducing the thickness of the 3D printer base 100 and making the structure of the 3D printer 1000 more compact. Figure 2 As shown, both ends of the bottom beam 201 extend out of the avoidance channel and are connected to one end of the two columns 202 respectively.
[0067] Figure 4 for Figure 1 An exploded view of the 3D printer base 100 in the illustrated embodiment.
[0068] See also Figure 3 and Figure 4 The 3D printer base 100 provided in this embodiment includes a top shell 10 and a bottom shell 20. The bottom shell 20 includes a first shell 21, a second shell 22, a third shell 23, and a fourth shell 24. The first shell 21, the second shell 22, the third shell 23, and the fourth shell 24 are respectively detachably connected to the top shell 10.
[0069] The 3D printer base 100 can be individually removed from any one of the first housing 21, the second housing 22, the third housing 23, and the fourth housing 24 during use. Therefore, when a component within the 3D printer base 100 requires maintenance, only the first housing 21, the second housing 22, the third housing 23, or the fourth housing 24 corresponding to the component can be removed, thereby facilitating maintenance of the 3D printer base 100.
[0070] In some embodiments, as Figure 3 As shown, the first and second housings 21, 22 are positioned opposite each other and spaced apart along a first direction Y. The third and fourth housings 23, 24 are both located between the first and second housings 21, 22 and distributed along a second direction X, where the second direction X intersects the first direction Y at a perpendicular angle or at an angle. This allows the first, second, third, and fourth housings 21, 22, 23, and 24 to be positioned at different locations on the top housing 10 and arranged in a reasonable manner for easy assembly and disassembly. For example, the third and fourth housings 23, 24 can be positioned near the center of the bottom housing 20.
[0071] In some embodiments, as Figure 3As shown, the third shell 23 is inwardly recessed to form a first avoiding slot 23a towards the direction of the top shell 10, and the fourth shell 24 is inwardly recessed to form a second avoiding slot 24a towards the direction of the top shell 10, the first avoiding slot 23a and the second avoiding slot 24a are communicated to form an avoiding passage along the second direction X, and the avoiding passage is used for allowing the bottom beam 201 (see Figure 2 ) of the gantry 200 to pass through. In this way, the bottom beam 201 can be installed by using the space on the side of the bottom shell 20 away from the top shell 10, so as to facilitate reducing the thickness of the 3D printer base 100 and making the structure of the 3D printer 1000 more compact. In use, the functional components of the 3D printer 1000 can be installed between the first shell 21 and the top shell 10, or installed between the second shell 22 and the top shell 10. Since the first shell 21, the second shell 22, the third shell 23 and the fourth shell 24 are separately arranged, when a functional component in the 3D printer base 100 needs to be repaired, only the first shell 21 or the second shell 22 corresponding to the functional component needs to be disassembled, without disassembling the third shell 23, the fourth shell 24 or the gantry 200, so as to facilitate the maintenance of the 3D printer base 100.
[0072] In some embodiments, as shown in Figure 4 , a containing space 100a is formed between the bottom shell 20 and the top shell 10, as shown in Figure 3 , the bottom shell 20 is provided with an opening 20a communicated with the first avoiding slot 23a or the second avoiding slot 24a, and the opening 20a is communicated with the containing space 100a. The 3D printer base 100 further comprises a Z-axis driving mechanism (not shown in the figure), which is arranged in the containing space 100a and is used for driving the nozzle assembly 300 to move along a third direction Z (see Figure 1 ) relative to the column 202, wherein the third direction Z is perpendicular to the first direction Y and the second direction X. The Z-axis driving mechanism is opposite to the opening 20a to connect the bottom beam 201 through the opening 20a. Optionally, as shown in Figure 3 , the opening 20a penetrates through the fourth shell 24 and the second shell 22 respectively.

In this way, the gap between the third housing 23 and the first housing 21 and the second housing 22 is reduced, and the gap between the fourth housing 24 and the first housing 21 and the second housing 22 is reduced, improving the shielding and protection effect of the bottom shell 20 on the accommodation space 100a.
