Exhaust method for 3D printing device
By designing circulating direct exhaust and circulating filtered airflow paths in 3D printing equipment, the problem that the return air mechanism cannot simultaneously achieve temperature uniformity and filtration is solved, enabling dynamic adjustment of the airflow path according to the material type, thereby improving printing quality and efficiency.

AI Technical Summary
In 3D printing equipment, the return air mechanism cannot achieve both temperature uniformity and filtration simultaneously. The presence of the filter element increases the return air resistance and affects the temperature uniformity effect.
A circulating direct exhaust flow path and a circulating filtered airflow path were designed. By controlling the airflow to switch between different paths, both temperature regulation and filtration can be achieved.
Filtering is performed when printing high-temperature materials to reduce the impact of exhaust gas; when printing low-temperature materials, the airflow circulation speed is increased to improve the efficiency of cavity temperature equalization and avoid the impact of filter element resistance.
