Finally, the purified gas is discharged into the natural environment to complete the purification and odor removal process. The problem of the peculiar smell that produces among the 3D printing process harm and the pollution of environment to operating personnel health is solved.

The invention is realized by adopting the following technical scheme:

the utility model provides a 3D printer odour removal purifier which characterized in that: the sealed box body is provided with a door, and a transparent observation window is arranged on the door; the bottom plate is provided with an adjustable buckle. Open the door and place the 3D printer, press from both sides tight fixed 3D printer through adjustable buckle. And the height can be adjusted to be in a horizontal state through the ground feet of the box body. The back of the box body is provided with a wiring opening, and the opening is sealed by a hole cover. Set up the shirt rim structure between the mounting panel of box and the box door frame, sealed bubble is cotton to structural pasting of shirt rim, and when box locking airtight state, can be with the cotton compaction of bubble when locking between the door plant, the filling gap realizes sealed effect.
