[0002] 3D printer, a machine of rapid prototyping technology, is a technology that uses powdered metal or plastic and other bondable materials to construct objects by printing layer by layer based on digital model files. In the past, it was often used to make models in the fields of mold manufacturing, industrial design, etc., and is now gradually being used for the direct manufacturing of some products, which means that this technology is becoming popular;

[0003] When a 3D printer is in use, it uses powdered metal or plastic and other bondable materials to construct objects, so the printer needs to be kept dust-free so that dust will not stick to the powdered metal or plastic and other bondable materials. Most of the common printers on the market currently use ventilation devices to discharge the dust inside the printer. However, this dust removal method has a low dust removal rate, and a small amount of dust will still enter the printer during ventilation.
