Description

Technical Field

[0001] The utility model relates to the technical field of 3D printers, in particular to a novel 3D printer display screen. Background Art

[0002] 3D printing is the product of the development of modern science and technology. At the end of the 19th century, the United States developed photographic sculpture and landform forming technology, and then the core manufacturing idea of ​​3D printing technology was born.

[0003] In the late 1980s, American scientists invented a printer that can print three-dimensional effects and successfully launched it on the market. 3D printing technology has matured and is widely used. 3D printers not only reduce the cost of three-dimensional objects, but also stimulate people's imagination.

[0004] A 3D printer, also known as a three-dimensional printer, is a machine using cumulative manufacturing technology, that is, rapid prototyping technology. It is based on a digital model file and uses special wax materials, powdered metals, or plastics and other adhesive materials to print layers of adhesive materials to create three-dimensional objects.

[0005] For example, patent application 202311289261.5 discloses a 3D printer for industrial design. In order to solve the problem that during the printing process of the 3D printer, a fixed plate is usually installed inside the machine body, and the product will be formed on the fixed plate. The fixed plate is inconvenient to level. When the fixed plate is tilted, it will affect the molding of the printed product, resulting in printing failure and poor practicality. By turning on the motor, the threaded rod can be driven to rotate, and the rotating rod can be rotated through the meshing connection of the conical tooth B and the conical tooth A, and the threaded barrel can be moved upward. Under the action of the connecting part and the connecting block, the fixed plate can be pushed to move upward. At this time, the limit rod slides in the perforation, which can limit the angle between the connecting part and the connecting block, thereby playing a role in leveling the fixed plate. The printing platform is embedded in the fixed plate to achieve the purpose of leveling the printing platform, which is convenient for 3D printing.

[0006] However, the traditional 3D printer display has an LVDS or M IPI interface for video output, and the connecting cables are far away, have many signal lines, and can only be fixed in position. Utility Model Content

[0007] The technical problem to be solved by the utility model is to overcome the shortcomings of the prior art and provide a novel 3D printer display screen. The display screen body and the PCB board connected thereto are provided, and a Raspberry Pi CM4 module is fixed on the PCB board. The Raspberry Pi CM4 module only needs to communicate with a plurality of slave devices with USB interfaces through a standard USB cable and a USB HUB. In this way, the display screen can be freely placed and the wiring is simple, and is suitable for all 3D printers on the market.

[0008] Another object of the utility model is to provide a novel 3D printer display screen, which utilizes a rotating arm to rotate on both sides of a shell, with a support plate fixed therebetween, so as to facilitate adjustment of the viewing angle and the angle of the rotating arm, thereby improving overall stability and freedom.

[0009] In view of this, the utility model provides the following technical solutions:

[0010] A novel 3D printer display screen comprises a display screen body and a PCB board connected to the display screen body, a Raspberry Pi CM4 module is fixedly mounted on the PCB board, a built-in MICRO / TF card holder is arranged on the PCB board, the display screen body and the PCB board are mounted inside a shell, and an adjustment bracket is arranged on the outer wall of the shell.
