[0046] The technical solutions in the embodiments of the present application will be described clearly and completely below in conjunction with the drawings in the embodiments of the present application.

[0047] 1 , which is a schematic diagram of a 3D printing system 1 according to an embodiment of the present invention. As shown in FIG1 , the 3D printing system 1 includes a 3D printer 100 and a feeding device 200 for providing printing material to the 3D printer 100 .

[0048] For ease of description, the length of the 3D printer 100 shown in Figure 1 is defined as the X-axis, the width of the 3D printer 100 is defined as the Y-axis, and the height of the 3D printer 100 is defined as the Z-axis. The X-axis, Y-axis, and Z-axis directions are mutually perpendicular. Furthermore, in the description of this application, "two surfaces are disposed opposite each other" means that the two surfaces are disposed toward each other, and "two surfaces are disposed opposite each other" means that the two surfaces are disposed opposite each other.

[0049] The 3D printer 100 includes a frame module 10, a printing module 20, and a print head 30. A feeder 200 is connected to the print head 30. During the feeding process, the printing material enters the print head 30 through a material pipe of the feeder 200. After being heated to a molten state by the print head 30, the material is extruded into the printing module 20 to print a three-dimensional object.

[0050] Specifically, the print head 30 includes an extruder assembly (not shown in FIG1 ) and a hot end (not shown in FIG1 ). The extruder assembly delivers the printing material provided by the feeder 200 to the 3D printer 100 to the hot end. The hot end has a heating function, heating the printing material to a molten state and extruding the molten printing material onto the printing module 20 .

[0051] Illustratively, the hot end includes heat sink fins, a nozzle, and a pipe located between the fins and the nozzle. The printing material passes through the heat sink fins, the pipe, and the nozzle in sequence. Specifically, the nozzle heats the printing material to a molten state, which is then extruded onto the print platform of the print module 20. As the print head 30 moves relative to the print module 20 along the printing path, the nozzle extrudes the molten printing material layer by layer onto different locations on the print platform, thereby printing a three-dimensional object.

[0052] Exemplarily, the extrusion assembly includes a driving wheel and a driven wheel disposed opposite the driving wheel, with the printing material passing between the driving wheel and the driven wheel. The driving wheel rotates in a first direction, driving the printing material toward the hot end; the driving wheel rotates in a second direction, opposite to the first direction, driving the printing material back to the feeding device 200.

[0053] Please refer to FIG. 2 and FIG. 3 . FIG. 2 is a schematic structural diagram of the frame module 10 and the print head 30 shown in FIG. 1 . FIG. 3 is a partial structural cross-sectional diagram of the frame module 10 shown in FIG. 2 along the AA direction.

[0054] As shown in Figure 2, the frame module 10 includes a first column 11, a second column 12, a top rod 13, a mounting base 14, and a guide rod 15. The first column 11 and the second column 12 are spaced apart. The top rod 13, the mounting base 14, and the guide rod 15 are all connected between the first column 11 and the second column 12 and extend along the Y-axis.

[0055] For the convenience of description, the width direction of the frame module 10 is consistent with the width direction of the 3D printer 100, that is, the Y-axis direction, the thickness direction of the frame module 10 is consistent with the length direction of the 3D printer 100, that is, the X-axis direction, and the height direction of the frame module 10 is consistent with the height direction of the 3D printer 100, that is, the Z-axis direction.

[0056] In some feasible implementations, the first column 11 and the second column 12 are both columns, and the first column 11 and the second column 12 are spaced apart.

[0057] Optionally, in some feasible embodiments, the first column 11 includes a first column 111 and a first end 112, wherein the first end 112 is connected to one end of the first column 111 along the Z-axis. In this embodiment, the first column 111 and the first end 112 are both substantially rectangular cubes. The first column 111 includes a first mounting surface 113, which is disposed on one side of the first column 111 along the Y-axis. The first end 112 includes a second mounting surface 114, which is disposed on one side of the first end 112 along the Y-axis. The first mounting surface 113 and the second mounting surface 114 are disposed in the same direction.

[0058] The second column 12 includes a second column 121 and a second end 122, which is connected to one end of the second column 121 along the Z-axis. In this embodiment, the second column 121 and the second end 122 are both substantially rectangular cubes. The second column 121 includes a third mounting surface 123, which is disposed on one side of the second column 121 along the Y-axis. The second end 122 includes a fourth mounting surface 124, which is disposed on one side of the second end 122 along the Y-axis. The third mounting surface 123 and the fourth mounting surface 124 are disposed in the same direction.

[0059] The first column 11 and the second column 12 both extend along the height direction (Z-axis direction) of the 3D printer 100 and are spaced apart along the width direction (Y-axis direction) of the 3D printer 100. Exemplarily, the first column 11 and the second column 12 can be arranged in parallel in the Y-axis direction. Specifically, along the Y-axis direction, the first mounting surface 113 and the third mounting surface 123 are arranged opposite to each other, and the second mounting surface 114 and the fourth mounting surface 124 are arranged opposite to each other. The spacing L2 between the first end 112 and the second end 122 is smaller than the spacing L1 between the first column 111 and the second column 121. Among them, the spacing L1 between the first column 111 and the second column 121 refers to the distance between the first mounting surface 113 and the third mounting surface 123; the spacing L2 between the first end 112 and the second end 122 refers to the distance between the second mounting surface 114 and the fourth mounting surface 124. In the present application, by reducing the distance between the first end 112 and the second end 122, when the base 21 is installed on the frame module 10, the base 21 can be more accurately confined between the first end 112 and the second end 122, thereby improving the matching accuracy between the base 21 and the frame module 10 and further enhancing the structural stability of the 3D printer 100.

[0060] One end of the push rod 13 is connected to the end of the first column 111 facing away from the first end 112, and the other end is connected to the end of the second column 121 facing away from the second end 122. The mounting base 14 is connected between the first mounting surface 113 of the first end 112 and the second mounting surface 114 of the second end 122. The push rod 13 and the mounting base 14 are spaced apart along the Z-axis. A guide rod 15 is located between the push rod 13 and the mounting base 14. Its ends along the Y-axis are slidably connected to the first column 111 and the second column 121, respectively. It is understood that the guide rod 15 can slide up and down along the Z-axis relative to the first column 11 and the second column 12. Simultaneously, the print head 30 is slidably connected to the guide rod 15, allowing it to move along the extension direction of the guide rod 15, i.e., the Y-axis. It is understood that after the print head 30 is installed in the frame module 10, the frame module 10 can achieve displacement of the print head 30 in the Y-axis and Z-axis directions.

[0061] As shown in Figure 3, the mounting base 14 includes a first mounting portion 141 and a second mounting portion 142. The second mounting portion 142 extends along the Y-axis and is connected between the first column 11 and the second column 12. For example, the second mounting portion 142 is connected between the first end 112 and the second end 122. One end of the first mounting portion 141 is fixedly connected to the second mounting portion 142, and the other end of the first mounting portion 141 protrudes from the second mounting portion 142 and extends along the length direction (X-axis direction) of the 3D printer 100.

[0062] The second mounting portion 142 is generally rectangular and includes a first side surface 1421, a second side surface 1422, a third side surface 1423, and two end surfaces (not labeled in FIG3 ). The first side surface 1421 and the second side surface 1422 are disposed opposite each other along the X-axis. The two end surfaces are disposed opposite each other along the Y-axis and are connected between the first side surface 1421 and the second side surface 1422. The third side surface 1423 is connected between the first side surface 1421 and the second side surface 1422, and is also connected between the two end surfaces.

[0063] The second mounting portion 142 is provided with a connecting groove (not shown in Figure 3) for mounting the first mounting portion 141. The connecting groove is formed on the third side surface 1423, is recessed toward the interior of the second mounting portion 142, and extends through the first side surface 1421 along the X-axis. In this embodiment, the connecting groove extends through the second mounting portion 142 along the X-axis, that is, through the first side surface 1421 and the second side surface 1422. It will be understood that the connecting groove in this embodiment is a through groove.

[0064] The second mounting portion 142 is further provided with a first ridge 1425 and a second ridge 1426. The first ridge 1425 is provided on the first side surface 1421 and protrudes in a direction away from the second side surface 1422 and extends along the Y-axis direction. The second ridge 1426 is provided on the second side surface 1422 and protrudes in a direction away from the first side surface 1421 and extends along the Y-axis direction. The second mounting portion 142 is further provided with a second fixing hole 1427, the opening of which is oriented in the same direction as the third side surface 1423. In this embodiment, there are multiple second fixing holes 1427. The multiple second fixing holes 1427 form two second fixing hole groups. The two second fixing hole groups are respectively a third sub-fixing hole group 1428 and a fourth sub-fixing hole group 1429. The third sub-fixing hole group 1428 is provided on the first ridge 1425, and the fourth sub-fixing hole group 1429 is provided on the second ridge 1426.

[0065] The third sub-fixing hole group 1428 is formed on the surface of the first protrusion 1425 facing the third side surface 1423 and is recessed away from the third side surface 1423. In this embodiment, the third sub-fixing hole group 1428 includes two second fixing holes 1427. Along the length of the second mounting portion 142, the two second fixing holes 1427 of the third sub-fixing hole group 1428 are located on either side of the connecting groove. In other embodiments, the number of second fixing holes 1427 in the third sub-fixing hole group 1428 is not specifically limited.

[0066] The fourth sub-fixing hole group 1429 is formed on the surface of the second protrusion 1426 facing the third side surface 1423 and is recessed away from the third side surface 1423.

The first mounting portion 141 includes a first surface 1411, a second surface 1412, and a third surface 1413. The second surface 1412 and the third surface 1413 are arranged opposite to each other along the Y-axis direction, and the first surface 1411 is connected between the second surface 1412 and the third surface 1413. In this embodiment, the first mounting portion 141 is a hollow body and can be prepared from a thin sheet metal part through processes such as bending, stamping, shearing, and welding.

[0068] The first mounting portion 141 is also provided with a first fixing hole 1414, the opening of which is oriented in the same direction as the first surface 1411. In this embodiment, there are multiple first fixing holes 1414. The multiple first fixing holes 1414 form two first fixing hole groups. The first fixing hole groups are both opened on the first surface 1411 and recessed toward the interior of the first mounting portion 141. The two first fixing hole groups are respectively a first sub-fixing hole group 1415 and a second sub-fixing hole group 1416, which are spaced apart along the Y-axis direction.

The first mounting portion 141 protrudes from the second mounting portion 142 along the X-axis direction to form a "T"-shaped mounting seat 14. The mounting seat 14 provided in this embodiment lowers the center of gravity of the frame module 10 by providing the first mounting portion 141 protruding from the second mounting portion 142 along the length direction (X-axis direction) of the 3D printer 100, thereby enhancing the structural stability of the frame module 10 and reducing the possibility of instability of the frame module 10.

[0070] The mounting base 14 is connected between the first column 11 and the second column 12. Specifically, the two end surfaces of the second mounting portion 142 are respectively connected to the first mounting surface 113 of the first end portion 112 and the second mounting surface 114 of the second end portion 122.

The base body 23 is provided with a receiving slot 26, a second mounting hole 235, a first retaining portion 236, a second retaining portion 237, and a mounting slot 238.

[0078] The opening of the receiving groove 26 faces the first surface 231, and the receiving groove 26 is recessed from the first surface 231 toward the second surface 232. The receiving groove 26 is used to accommodate the sliding member 24. The second mounting hole 235 passes through the base body 23 along the Z-axis direction. In this embodiment, there are multiple second mounting holes 235, and the multiple second mounting holes 235 form two second mounting hole groups. The two second mounting hole groups are respectively a third sub-mounting hole group 2351 and a fourth sub-mounting hole group 2352. Along the X-axis direction, the third sub-mounting hole group 2351 and the fourth sub-mounting hole group 2352 are arranged at intervals. In this embodiment, the number of second mounting holes 235 in the third sub-mounting hole group 2351 is two. Among them, along the Y-axis direction, the two second mounting holes 235 of the third sub-mounting hole group 2351 are respectively located on both sides of the receiving groove 26. The number of second mounting holes 235 in the fourth sub-mounting hole group 2352 is two. Along the Y-axis direction, the two second mounting holes 235 of the fourth sub-mounting hole group 2352 are respectively located on both sides of the receiving groove 26. In other embodiments, the number of second mounting holes 235 included in the third sub-mounting hole group 2351 and the fourth sub-mounting hole group 2352 is not specifically limited.

[0079] The first retaining portion 236 is formed on the third surface 233 and is recessed toward the fourth surface 234. It extends through the first surface 231 and the second surface 232 along the Z-axis. The second retaining portion 237 is formed on the fourth surface 234 and is recessed toward the third surface 233. It extends through the first surface 231 and the second surface 232 along the Z-axis. The mounting groove 238 is formed on the second surface 232 and extends through the base body 23 along the Y-axis. In this embodiment, the mounting groove 238 communicates with both the first retaining portion 236 and the second retaining portion 237 along the Y-axis. The mounting groove 238 is used to accommodate the mounting base 14 and the motor 40.

[0080] Please also refer to Figure 7, which is a schematic diagram of the assembly structure of the 3D printer 100 shown in Figure 1. The printing module 20 omits the cover 25.

[0081] For ease of description, the direction from the printing module 20 toward the guide rod 15 is defined as the positive Z-axis direction, and the direction from the guide rod 15 toward the printing module 20 is defined as the negative Z-axis direction. The terms "up" and "down" and other directional terms used in the embodiments of this application are based on the orientation shown in FIG7 of the specification, with the positive Z-axis direction being defined as "up" and the negative Z-axis direction being defined as "down." These terms do not limit the actual application of the 3D printer 100.

[0082] The 3D printer 100 also includes a fixing member 50, which is used to connect the base 21 and the mounting base 14. The fixing member 50 includes a first fixing member 51 and a second fixing member 52. The first fixing member 51 is used to connect the sliding member 24 and the first mounting portion 141, and the second fixing member 52 is used to connect the base body 23 and the second mounting portion 142. In this embodiment, the first fixing member 51 and the second fixing member 52 are both screws. The first fixing member 51 is used to pass through the first mounting hole 244 and the first fixing hole 1414 in sequence to threadably connect the sliding member 24 and the first mounting portion 141. The second fixing member 52 is used to pass through the second mounting hole 235 and the second fixing hole 1427 in sequence to threadably connect the base body 23 and the second mounting portion 142.

[0083] In other embodiments, the fixing member 50 may also be an adhesive layer to bond the base 21 and the mounting base 14. Alternatively, the fixing member 50 may also be a magnetic member. Exemplarily, the fixing member 50 may include two magnets with opposite magnetic properties, one magnet fixedly connected to the surface of the base 21 facing the mounting base 14, and the other magnet fixedly connected to the surface of the mounting base 14 facing the base 21. When the base 21 is mounted on the mounting base 14, the two magnets with opposite magnetic properties face each other, generating an attractive force to magnetically connect the base 21 and the mounting base 14.

[0084] Exemplarily, the first fixing member 51 includes at least two sub-fixing members, which are located on both sides of the conveyor belt 243 along the Y-axis. For example, an adhesive layer is applied on both sides of the conveyor belt 243 along the Y-axis between the base 21 and the mounting base 14; or magnetic elements are provided on both sides of the conveyor belt 243 along the Y-axis between the base 21 and the mounting base 14.

[0085] The printing module 20 is installed in the frame module 10. The 3D printer 100 provided in the embodiment of the present application integrates parts and components into the frame module 10 and the printing module 20, respectively, so that the 3D printer 100 can be assembled by simply connecting the frame module 10 and the printing module 20. This significantly simplifies the assembly steps of the 3D printer 100, reduces the assembly difficulty, and reduces the assembly time. At the same time, the detachable frame module 10 and printing module 20 can reduce the volume and cost of the 3D printer 100 during packaging, transportation, and storage, compared to an integral 3D printer 100, thereby reducing logistics costs and storage costs.

[0086] Specifically, the base 21 of the printing module 20 is disposed between the first column 11 and the second column 12. The first retaining portion 236 retains the first column 11, and the second retaining portion 237 retains the second column 12. In this embodiment, the first retaining portion 236 of the base body 23 retains the first end 112 of the first column 11, and the second retaining portion 237 retains the second end 122. This restricts the movement of the base 21 in the Y-axis and X-axis directions, thereby improving the structural stability of the 3D printer 100.

[0087] In other embodiments, the first pillar 11 and the second pillar 12 may both be cylindrical. The first retaining portion 236 may retain at any portion of the outer circumference of the first pillar 11, not limited to the ends; and the second retaining portion 237 may retain at any portion of the outer circumference of the second pillar 12, not limited to the ends.

[0088] The mounting base 14 and the motor 40 are both housed within the mounting slot 238 of the base body 23. The second surface 232 of the base body 23 and the surface of the mounting base 14 facing away from the guide rod 15 are coplanar (within a certain tolerance). The mounting base 14 is housed within the mounting slot 238 of the base 21, further limiting the movement of the base 21 in the Y- and X-axis directions, thereby improving the assembly stability of the 3D printer 100. Furthermore, the coplanarity of the second surface 232 of the base body 23 and the surface of the mounting base 14 facing away from the guide rod 15 ensure that, during operation, the assembled 3D printer 100 can both contact a placement surface, such as the ground or a tabletop. This improves the structural stability of the 3D printer 100 and enhances its operational stability.

[0089] The first mounting hole 244 of the slider 24 communicates with the first fixing hole 1414 of the first mounting portion 141. The first fixing member 51 passes through the first mounting hole 244 and the first fixing hole 1414 in sequence along the negative Z-axis direction. The second mounting hole 235 of the slider 24 communicates with the second fixing hole 1427 of the second mounting portion 142. The second fixing member 52 passes through the second mounting hole 235 and the second fixing hole 1427 in sequence along the negative Z-axis direction. Specifically, each first mounting hole 244 of the first sub-mounting hole group 245 communicates with a first fixing hole 1414 of the first sub-fixing hole group 1415, and each first mounting hole 244 of the second sub-mounting hole group 246 communicates with a first fixing hole 1414 of the second sub-fixing hole group 1416. Along the Y-axis, the first sub-mounting hole group 245 and the second sub-mounting hole group 246 are located on either side of the conveyor belt 243, respectively. This helps to improve the connection stability between the conveyor belt 243 and the slider 24 and the first mounting base 14. Each second mounting hole 235 of the third sub-mounting hole group 2351 communicates with a second fixing hole 1427 of the third sub-fixing hole group 1428, and each second mounting hole 235 of the fourth sub-mounting hole group 2352 communicates with a second fixing hole 1427 of the fourth sub-fixing hole group 1429. The third sub-fixing hole group 1428 is provided on the first protrusion 1425, and the fourth sub-fixing hole group 1429 is provided on the second protrusion 1426. Therefore, the third sub-fixing hole group 1428 and the fourth sub-fixing hole group 1429 are arranged opposite each other along the X-axis, which helps to improve the connection stability between the base body 23 and the second mounting base 14.

[0090] The 3D printer 100 provided in the embodiment of the present application is provided with a mounting base 14 connected to the first column 11 and the second column 12, so that the mounting base 14 is connected to the base 21 to form the 3D printer 100. The 3D printer 100 provided in the embodiment of the present application can be assembled by simply connecting the mounting base 14 to the base 21, which simplifies the assembly steps of the 3D printer 100 and reduces assembly time. Furthermore, the large connection area between the mounting base 14 and the base 21 ensures a secure connection, thereby improving the structural stability of the 3D printer 100 and enhancing the operational stability of the 3D printer 100.

[0091] Please refer to Figures 8 to 10. Figure 8 is a schematic diagram of the first assembly of the printing module 20 and the frame module 10 shown in Figure 1. Figure 9 is a schematic diagram of the second assembly of the printing module 20 and the frame module 10 shown in Figure 1. Figure 10 is a schematic diagram of the third assembly of the printing module 20 and the frame module 10 shown in Figure 1. The assembly process of the 3D printer 100 is as follows:

[0092] First, the printing module 20 is tilted around the X-axis at a predetermined angle and then inserted between the first column 11 and the second column 12 of the frame module 10 .

[0093] As shown in FIG8 , for the convenience of description, the width direction of the frame module 10 is consistent with the width direction of the 3D printer 100, that is, the Y-axis direction, the thickness direction of the frame module 10 is consistent with the length direction of the 3D printer 100, that is, the X-axis direction, and the height direction of the frame module 10 is consistent with the height direction of the 3D printer 100, that is, the Z-axis direction.

[0094] In this embodiment, the printing module 20 in the original state is rotated 45 degrees counterclockwise around the X-axis and then inserted between the first cylinder 111 and the second cylinder 121, as well as between the guide rod 15 and the mounting base 14. It can be understood that the predetermined angle of this embodiment is 45 degrees. The printing module 20 in the original state refers to the situation that the first surface 231 of the base body 23 of the printing module 20 faces the guide rod 15 and is parallel to the XY plane (a certain error is allowed). After the printing module 20 in the original state is rotated 45 degrees around the X-axis, the angle between the first surface 231 and the XY plane is 45 degrees. In other embodiments, the predetermined angle can be 30 degrees, 60 degrees, 90 degrees or other angles to facilitate the insertion of the printing module 20 in the frame module 10, and the specific angle is not limited.

[0095] Then, the printing module 20 is rotated around the X axis by a predetermined angle so that the first holding portion 236 of the printing module 20 holds the first column 111 of the frame module 10 and the second holding portion 237 of the printing module 20 holds the second column 121 of the frame module 10 .

[0096] As shown in Figure 9, the tilted printing module 20 is rotated 45 degrees clockwise about the X-axis, so that the first surface 231 of the printing module 20 faces the guide rod 15 and is parallel to the XY plane (a certain error is allowed). At this point, the first clamping portion 236 of the printing module 20 clamps the first column 111 of the frame module 10, and the second clamping portion 237 of the printing module 20 clamps the second column 121 of the frame module 10.

[0097] Next, the printing module 20 is mounted on the mounting seat 14 of the frame module 10 , so that the first holding portion 236 holds the first end portion 112 of the frame module 10 , and the second holding portion 237 holds the second end portion 122 of the frame module 10 .

[0098] As shown in Figures 3, 6 and 10, the printing module 20 is moved downward along the negative direction of the Z axis and installed on the mounting base 14. Specifically, the mounting base 14 is accommodated in the mounting groove 238 of the base body 23, and the second surface 232 of the base body 23 and the surface of the mounting base 14 facing away from the guide rod 15 are in the same plane (a certain range of error is allowed). The first clamping portion 236 of the base body 23 clamps the first end 112 of the first column 11, and the second clamping portion 237 clamps the second end 122. Because the distance L2 between the first end 112 and the second end 122 is smaller than the distance L1 between the first column 111 and the second column 121, the base body 23 can be more accurately confined between the first end 112 and the second end 122, thereby improving the matching accuracy of the printing module 20 and the frame module 10 and further enhancing the structural stability of the 3D printer 100.

[0099] Finally, the first fixing member 51 is passed through the first mounting hole 244 and the first fixing hole 1414 in sequence, and the second fixing member 52 is passed through the second mounting hole 235 and the second fixing hole 1427 in sequence to fix the printing module 20 and the frame module 10, and then the cover plate 25 is covered to partially close the receiving groove 26.

[0100] As shown in Figure 7, along the negative Z-axis direction, the first fixing member 51 sequentially passes through the first mounting hole 244 and the first fixing hole 1414 to secure the slider 24 to the first mounting seat 14, and the second fixing member 52 sequentially passes through the second mounting hole 235 and the second fixing hole 1427 to secure the base body 23 to the second mounting seat 14. During assembly of the 3D printer 100 provided in the embodiment of the present application, the printing module 20 is mounted on the mounting seat 14 of the frame module 10 along the negative Z-axis direction. The first fixing member 51 sequentially passes through the first mounting hole 244 and the first fixing hole 1414 along the negative Z-axis direction, and the second fixing member 52 sequentially passes through the second mounting hole 235 and the second fixing hole 1427 along the negative Z-axis direction. Therefore, the assembly direction of the 3D printer 100 provided in the present application is consistently along the negative Z-axis direction, that is, along the guide rod 15 toward the mounting seat 14, and does not occur along the positive Z-axis direction. It can be understood that during the assembly process, the 3D printer 100 provided in this application has a consistent assembly direction and always maintains a top-down working mode. There is no need to flip the printer over, which reduces the assembly difficulty and significantly reduces the assembly time of the 3D printer 100.
