[0002] 3D printing, also known as a type of rapid prototyping technology, is a technique that constructs objects by layer-by-layer printing using adhesive materials like powdered metal or plastic, based on digital model files. 3D printing is usually achieved with digital material printers, often used in mold manufacturing, industrial design, and
other fields to make models. Gradually, it has been used for
the direct manufacturing of some products, with parts made
using this technology. This technology has been applied in
jewelry, footwear, industrial design, architecture, engineering, and construction, automotive, aerospace, dental and medical industries, education, geographic information systems, civil engineering, firearms, and other fields. Nowadays, as 3D printing technology matures, the types and functions of 3D printers are becoming increasingly diversified.
[0003] However, commonly used 3D printers can only control the printer device to move and adjust in a certain
direction, resulting in less precise adjustment of the printing position. The adjustment range is limited and can’t control the printing operation smoothly, thus reducing the printing effect and quality. To solve these problems, we propose a ground rail type printer.

[0004] Addressing the shortcoming of the prior art, the present invention provides a ground rail type printer, which
solves the problem that when the 3D printer is used, only the printer device can be controlled to move and adjust in specific directional positions, resulting in the printing position adjustment of the printer device is not accurate enough, the adjustment range is limited, and the printing operation cannot be controlled smoothly. Such constraints inevitably lead to a decrease in both the efficiency and quality of the
printing outcome.
[0005] To achieve the above purpose, this application provides the following technical solution. A ground rail type printer, comprising two X-axis guide rail assemblies, two
Z-axis guide rail assemblies, and a Y-axis guide rail assembly assembly. The two X-axis guide rail assemblies are both equipped with a slidingly mounted connecting plate. The
bottom ends of the two Z-axis guide rail assemblies are
respectively fixedly mounted on the tops of the corresponding connecting plates by screws. A first rack is fixedly
mounted on the sides of the two X-axis guide rail assemblies
that are closest to each other. Both connecting plates are
equipped with X-axis drive assemblies. Sliding supports are slidingly mounted on the two Z-axis guide rail assemblies. The two ends of the Y-axis guide rail assembly are respectively fixedly connected to the corresponding sliding supports. A printer frame is slidingly mounted on the Y-axis
guide rail assembly. The printer frame is equipped with a Y-axis drive assembly. Fixed supports are fixedly mounted

mounted on the output shaft end of the second servo motor. The second rack is fixedly mounted on the side of the printer frame near the second servo motor. The second drive gear meshes with the second rack.
[0010] Preferably, the printer frame comprises two fixed plates, four screws, four positioning rings, and two guide wheels. The two fixed plates are respectively located on both
sides of the Y-axis guide rail assembly. The two ends of the
screws are respectively installed on the corresponding fixed plates by nuts. The four positioning rings are respectively set on the corresponding screws. The two guide wheels are rotatably installed on the sides of the two fixed plates that are
