Description

Technical Field

[0001] The utility model relates to the technical field of 3D printers, in particular to a sliding machine cover of a 3D printer. Background Art

[0002] 3D printers use light sources such as lasers or LEDs to spray photosensitive resin layer by layer onto a printing platform. Then, according to the instructions of the 3D model file, the light beam irradiates the photosensitive resin at a specific position, causing it to undergo a photocuring reaction, converting the liquid resin into a solid state, and finally constructing a 3D printed model layer by layer.

[0003] At present, there are two main types of hoods for photosensitive resin 3D printers. One is that the hood can be removed directly, and the hood needs to be disassembled and assembled each time it is used, which is cumbersome to use; the other is that the hood is hinged to the column of the fixed vertical linear module, and the hood flips backward to open. Although it is more convenient to use, the hood flipping backward will occupy the space behind the printer. Therefore, when placing the 3D printer, it is necessary to reserve the space behind it, and it cannot be placed against the wall, resulting in a waste of desktop space. Utility Model Content
