Description

Air guide structure of 3D printer and 3D printer Technical Field The utility model relates to the technical field of 3D (three-dimensional), in particular to an air guide structure of a 3D printer and the 3D printer. Background In the printing process of the existing 3D printer, black smoke can be generated when powder materials in the printing forming bin are burnt or thermally decomposed, and the black smoke can be diffused to the top of the printing forming bin to cause 'black top', so that the printing forming bin has potential harm to the environment and health. The dust and carbide that produce in the printing process is an important link, in order to realize this function, usually can set up clean system in the printer inside, get rid of dust and carbide through gas circulation flow, wind guiding structure is clean system's important part, current wind guiding structure's wind channel is longer, generally divide into three segmentation, the entry section, drainage section and exit segment, current wind guiding structure generally can be with the longer that the drainage section set up, when the air current passes through the drainage section from the entry section, the space is great, moreover, the air current after producing the turbulence is in unordered state at the juncture of drainage section and exit segment easily, the air current after producing the turbulence does not have the direction, the wind guiding hole sets up generally on the wind guiding lid in addition, usually just a hole, so when the air current reachs the wind guiding lid, also can be blocked by the wind guiding lid, the air current also can form the current in disorder here, consequently when entering into the printing the shaping storehouse through the wind guiding hole, the air current is not straight, but have certain angle for dust and carbide fly around in the printer inside, be difficult to get rid of, and the purpose that the carbide is printed on the piece is printed on the attached to the quality.
