[0023] like Figures 1 to 3 As shown, an industrial 3D printer frame structure includes a mounting platform 1, a main frame 2 and a sheet metal part 3, wherein the sheet metal part 3 is embedded and fixed to the inner side of the main frame 2; the mounting platform 1 is installed on the top of the main frame 2. The specific installation process is as follows: first, the sheet metal part 3 is embedded and installed into the inner wall of the main frame 2 and fixed into an integrated configuration, and then the mounting platform 1 is fixedly installed on the top of the main frame 2 to complete the assembly of this frame; when in use, the 3XY motion platform is installed on the mounting platform 1. The advantages of this frame structure are: since the main frame and the sheet metal part are integrated, the bottom base of the 3D printer is laid, which can reduce the problem of no base or setting the base on the sheet metal during manual installation, thereby ensuring the printing accuracy of the printer; the mounting platform is installed on the top of the main frame by welding, and then processed by the gantry milling, which can well control the base of the 3D printer and avoid various problems in the later installation; the structure of this frame structure is stable, the assembly difficulty is low, and the requirements for manual operation are greatly reduced, which can improve the installation efficiency and reduce the defect rate, thereby improving the stability, printing quality and accuracy of the printer, and the printer using this frame structure can print oversized models.

[0024] Furthermore, the sheet metal 3 and the main frame 2 are fastened by welding; after the sheet metal 3 is fitted into the main frame 2, the two are fastened into one by welding. The assembly process is simple and convenient, and the difficulty is greatly reduced, thereby improving the installation efficiency and accuracy and reducing the defective rate.

[0025] Furthermore, the main frame 2 includes a bottom frame 21 and a plurality of support members 22 . The plurality of support members 22 are fixedly connected to the bottom frame 21 to form a frame structure with two ends opened, so that the sheet metal member 3 can be conveniently nested into the main frame 2 from one end.

[0026] Furthermore, a plurality of support members 22 form a limited angle 221 , and the corner edge of the sheet metal member 3 is fitted into the limited angle 221 , thereby ensuring the connection accuracy and stability between the main frame 2 and the sheet metal member 3 .

[0027] Furthermore, it also includes a fixing member 4, which is detachably connected between the plurality of supporting members 22. After the mounting platform 1 is mounted on the top of the plurality of supporting members 22, the detachable fixing members 4 are installed on both sides between the plurality of supporting members 22, so that the mounting platform 1 can be fine-tuned and aligned with the plurality of supporting members 22 during the installation process. After the fixing members 4 are installed, the structure of the main frame 2 can be made more stable, and the printing accuracy can be ensured.

[0028] Furthermore, a 5 is provided at the bottom of the bottom frame 21 to facilitate movement of the frame structure and operation.
