Description

Technical Field

[0001] This utility model relates to the field of 3D printing technology, and in particular to a 3D printer structure capable of multi-color printing. Background Technology

[0002] 3D printers, also known as three-dimensional printers, are rapid prototyping devices. They create three-dimensional objects by printing layers of adhesive materials, such as special waxes, powdered metals, or plastics, based on a digital model file. Currently, 3D printers are primarily used for product manufacturing, constructing objects through a layer-by-layer printing process.

[0003] With the development of technology, people have increasingly higher demands for the functions of 3D printers. A 3D printer mainly consists of a motor, parallel arms, effectors, and a heated bed. Most 3D printers cannot continue printing when changing filaments for different colors during multi-color printing, affecting printing efficiency and hindering efficient time utilization. Furthermore, most 3D printers can only print one object at a time, resulting in lower printing efficiency. Utility Model Content

[0004] In order to solve the problems in the prior art, this utility model provides a 3D printer structure that can realize multi-color printing.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0006] A 3D printer structure capable of multi-color printing includes a heated bed mechanism and multiple sets of 3D printers. The printing areas of the multiple sets of 3D printers all act on the heated bed mechanism, and the printing areas of the multiple sets of 3D printers have overlapping areas.

[0007] Furthermore, the heated bed mechanism includes a fixed heated bed; around the heated bed, multiple sets of 3D printers are fixedly distributed circumferentially, and the printing ranges of the multiple sets of 3D printers overlap in the center of the heated bed.

[0008] Furthermore, the heated bed mechanism includes multiple heated beds, each with a fixed position; multiple sets of 3D printers are also fixed in position, and the printing range of each 3D printer acts on more than two heated beds.

[0009] Furthermore, the arrangement of the heated beds and 3D printers is as follows: multiple heated beds are arranged in a straight line, and multiple sets of 3D printers are also distributed in a corresponding straight line.

[0010] Furthermore, the arrangement of the heated beds and 3D printers is as follows: multiple heated beds are arranged circumferentially, and multiple sets of 3D printers are also distributed circumferentially accordingly.

[0011] Furthermore, the 3D printer includes a print head and a connecting arm. One end of the connecting arm is connected to the print head, and the other end of the connecting arm is connected to the frame. The translation of the print head is controlled by the connecting arm.

[0012] Furthermore, the connecting arm is a parallel arm. The 3D printer has three sets of parallel arms, two of which are shorter and the other is longer. The print head connects to the intersection of the three sets of parallel arms.

[0013] Furthermore, the connecting arm is a robotic arm. The robotic arm of the 3D printer has three joints: the first joint, the second joint, and the third joint. The first joint is mounted on the frame, the second joint is rotatably connected to the first joint, and the third joint is rotatably connected to the second joint. The print head is mounted on the movable end of the third joint.

[0014] Furthermore, the connecting arm is a spider arm.

[0015] The beneficial effects of this utility model are:

[0016] This invention enables multi-color printing in overlapping areas of the printing range, achieving efficient use of time. During printing, one group of 3D printers can print an object while other groups of 3D printers change the consumables of the required colors and wait to print, thereby saving printing time.

[0017] This invention can also be used to print objects using a set of 3D printers.

[0018] This invention can also use multiple 3D printers to print in their respective areas near the heated bed, achieving simultaneous printing and improving printing efficiency. Attached Figure Description

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

[0023] 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.

[0024] This utility model provides a 3D printer structure capable of multi-color printing, including a heated bed mechanism and multiple sets of 3D printers. The printing range of the multiple sets of 3D printers all acts on the heated bed mechanism, and the printing ranges of the multiple sets of 3D printers have overlapping areas.

[0025] The specific structure and principle of the present invention will be described in detail below with reference to various embodiments.

[0026] Example 1

[0027] like Figure 1 As shown, in this embodiment, the heated bed mechanism includes a heated bed 1 with a fixed position; with the heated bed 1 as the center, two sets of 3D printers are arranged opposite each other on both sides of the heated bed.

[0028] The 3D printer includes a print head 21, a parallel arm 22, a frame 23, and a filament holder 24. One end of the parallel arm 22 is connected to the print head 21, and the other end of the parallel arm 22 is mounted on a vertical track in the frame 23. The parallel arm 22 controls the translation of the print head 21. The filament holder 24 is located at the top of the frame 23.

[0029] The 3D printer has three sets of parallel arms, two of which are shorter and the third is longer. The print head connects to the intersection of the three sets of parallel arms, thus enabling the print head 21 to achieve a large range of translation. This ensures that the printing areas of the two sets of 3D printer print heads 21 overlap at the center of the heated bed 1.

[0030] This embodiment has the following operating modes:

[0031] (1) Multi-color printing can be performed in the overlapping area of ​​the printing range, i.e. the center of the heated bed, to make efficient use of time; during printing, one group of 3D printers can print objects while other groups of 3D printers change the consumables of the required colors and wait to print, thereby saving printing time.

[0032] (2) Alternatively, a set of 3D printers can be used to print objects, while other 3D printers are temporarily left idle.

[0033] (3) Two 3D printers can also be used to print in their respective areas near the heated bed, i.e. at the edge of the heated bed, to achieve simultaneous printing and improve printing efficiency.

[0034] Example 2

[0035] like Figure 2 As shown, the difference between this embodiment and Embodiment 1 is that there are three 3D printers arranged in a triangular pattern, with a heated bed 1 located in the middle.

[0036] Example 3

[0037] like Figure 3 As shown, in this embodiment, the heated bed mechanism includes three heated beds 1, each with a fixed position. The three heated beds 1 are arranged in a straight line at intervals.

[0038] It also includes two 3D printers, which are located on one side of the heated bed 1 queue and between two adjacent heated beds 1.

[0039] The 3D printer includes a print head 21, a robotic arm 25, a frame 23, and a filament support 24. One end of the robotic arm 25 is connected to the print head 21, and the other end of the robotic arm 25 is mounted on a vertical track of the frame 23.

[0040] The robotic arm 25 has three arm joints: the first arm joint, the second arm joint, and the third arm joint. The first arm joint is mounted on the vertical track of the frame 23. The second arm joint is rotatably connected to the first arm joint, and the third arm joint is rotatably connected to the second arm joint. The print head 21 is mounted on the movable end of the third arm joint, thereby enabling the print head 21 to move between two adjacent heated beds 1, so that the printing range of the print head can act on the two adjacent heated beds.

[0041] This embodiment has the following operating modes:

[0042] (1) Multi-color printing can be performed in the overlapping area of ​​the printing range, i.e., the intermediate heated bed, to make efficient use of time; during printing, one group of 3D printers can print objects while other groups of 3D printers change the consumables of the required colors and wait to print, thereby saving printing time.

[0043] (2) Two 3D printers can be used to print on their respective adjacent heated beds to achieve simultaneous printing and improve printing efficiency.

[0044] Example 4

[0045] The difference between this embodiment and Embodiment 1 is that the 3D printing mechanism in this embodiment adopts the form of a spider arm, which is mounted on the frame and the movable end of the spider arm is connected to the print head.
