Description

Technical Field

[0001] This utility model relates to the field of 3D printing technology, and in particular to a multi-degree-of-freedom three-dimensional printing device. Background Technology

[0002] 3D printers, also known as three-dimensional printers, are rapid prototyping devices. They create three-dimensional objects by printing layers of a digital model file, using special waxes, powdered metals, or plastics as adhesives. Currently, 3D printers are used to manufacture products, employing a layer-by-layer printing method to construct objects.

[0003] With the development of technology, the types and functions of 3D printing are becoming increasingly diverse. Furthermore, the demand for 3D printers capable of multi-color printing is becoming more prominent. Currently, there are many ways to achieve multi-color printing of models, such as using multiple print heads with different colors of filaments, or using a single print head connected to an external feeding mechanism.

[0004] In both of these methods, when a 3D printer uses multiple print heads, its movement space is greatly reduced because multiple print heads are installed at the printing end. In addition, the installation accuracy of the parallel print heads is required to avoid interference and collision between the print heads and the model, so the print heads need to be kept at the same height. 3D printers using a material changing mechanism need to completely extrude the original consumables during the material changing process, resulting in material waste. In addition, printing needs to be stopped during material changing, which takes a long time. Utility Model Content

[0005] In order to solve the problems in the prior art, this utility model provides a multi-degree-of-freedom 3D printing device.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0029] The accompanying drawings are for illustrative purposes only and should not be construed as limiting the scope of this patent. To better illustrate this embodiment, some components in the drawings may be omitted, enlarged, or reduced, and do not represent the actual dimensions of the product. It is understandable to those skilled in the art that some well-known structures and their descriptions may be omitted in the drawings. Detailed Implementation

[0030] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0031] Example 1

[0032] like Figure 1 and Figure 2 As shown, this embodiment provides a multi-degree-of-freedom 3D printing device, including two 3D printers and a moving mechanism that works in conjunction with the 3D printers. The number of 3D printers is not limited to this; in other embodiments, it can be arbitrarily set according to requirements.

[0033] The 3D printer includes a print head 21, a spider arm 25, a frame 23, and a filament holder 24. Due to the use of a spider arm, the frame 23 is a top plate located above the spider arm 25. Thus, the lower end of the spider arm 25 is connected to the print head 21, and the upper end of the spider arm 25 is mounted on the frame 23.

[0034] The heated bed mechanism includes three heated beds 1, the positions of which are fixed. The three heated beds 1 are arranged in a straight line at intervals, forming a heated bed queue. The number of heated beds 1 is not limited to this; in other embodiments, they can be arbitrarily set according to requirements.

[0035] To accommodate the top-plate frame 23 and facilitate the application of the print head 21 to the heated bed 1, the moving mechanism includes a guide rail 80 positioned above and parallel to the heated bed array. Both 3D printers are slidably mounted on the guide rail 80. Each of the two 3D printers is connected to a transmission mechanism, which is arranged opposite to each other at both ends of the guide rail, enabling independent movement of the 3D printers on the guide rail 80.

[0036] In this embodiment, two parallel guide rails 80 are provided, and dovetail-shaped guide rails are selected. The transmission mechanism is a lead screw 81 arranged in parallel at the middle position of the two guide rails 80. One end of the lead screw 81 is connected to a motor 82, and the nut seat on the lead screw 81 is connected to the frame 23 of the corresponding 3D printer.

[0037] When the transmission mechanism is working, the motor 82 drives the lead screw 81 to rotate, which in turn drives the frame 23 to move on the guide rail 80 through the nut seat, thereby realizing the movement of the corresponding 3D printer on the guide rail 80.

[0038] In this way, both 3D printers can be moved to the middle position of the guide rail 80. The two 3D printers overlap at the middle position of the guide rail 80 to form an intersection area, and the heated bed 1 at the middle position is located in the intersection area.

[0039] Based on the above, this embodiment forms the following working mode:

[0040] (1) Multicolor printing can be performed on the heated bed in the printing intersection area to make efficient use of time; during printing, the 3D printer moves away after printing on the heated bed, and another 3D printer (with consumables of other colors mounted on the consumable bracket) moves above the heated bed to print again.

[0041] (2) Two 3D printers can be used to print on their respective adjacent heated beds to achieve simultaneous printing and improve printing efficiency.

[0042] Example 2

[0043] like Figure 3 As shown, the difference between this embodiment and Embodiment 1 is that:

[0044] The structure of the 3D printing mechanism is different. In this embodiment, the 3D printer adopts the form of a robotic arm. The 3D printer includes a print head 21, a robotic arm 26, a frame 23, and a filament support. Because a robotic arm is used, the frame 23 is in the form of a column, one end of the robotic arm 26 is connected to the frame 23, and the other end of the robotic arm 26 is connected to the print head 21.

[0045] The guide rail arrangement differs. To accommodate the column-shaped frame 23 and facilitate the print head 21's action on the heated bed 1, the guide rail 80 is located at the bottom side of the heated bed array. The frame 23 is slidably connected to the guide rail, and the transmission mechanism is connected to the frame 23. The structure and principle of the transmission mechanism are the same as in Embodiment 1.

[0046] Example 3

[0047] like Figure 4 and Figure 5 As shown, the difference between this embodiment and Embodiment 1 is that:

[0048] The structure of the 3D printing mechanism is different. In this embodiment, the 3D printer adopts a parallel arm configuration. The 3D printer includes a print head 21, a parallel arm 22, a frame 23, and a filament support 24. Due to the use of a parallel arm, the frame 23 is frame-shaped, the print head 21 is located at the center inside the frame 23, one end of the parallel arm 22 is connected to the frame 23, and the other end of the parallel arm 22 is connected to the print head 21.

[0049] The guide rail arrangement differs. To accommodate the frame-type frame 23 and facilitate the printhead 21's action on the heated bed 1, guide rails 80 are located on both sides of the bottom of the heated bed array. The frame 23 is slidably connected to the guide rails, and the transmission mechanism is connected to the frame 23. The structure and principle of the transmission mechanism are the same as in Embodiment 1.

[0050] Example 4

[0051] The difference between this embodiment and embodiments one, two, or three is that multiple heated beds are arranged in a circular pattern to form a circular heated bed queue, and the guide rails are also arranged in a corresponding circular pattern.
