With the leapfrog development of industry and the demand for manufacturing, more and more 3D printer equipment is being invested in the manufacturing industry. Due to the large amount of smoke generated during the powder sintering process, in order to protect the production environment and the health of operators, air filters are needed to intercept harmful substances in the dust and smoke.

　　The 3D printer air filter produced by our company adopts a metal frame, glass fiber filter paper, and the first and second filters are connected with buckles, which has good universality, convenient and fast installation. The sealing strip at the connection adopts a seamless one-time forming structure, ensuring the airtightness of the product.
