It is based on a digital model file, using special wax materials, powdered metal or plastic and other adhesive materials to print layers of adhesive materials to make three-dimensional objects. At present, 3D printers are used to manufacture products. The technology of constructing objects by printing layer by layer. The principle of 3D printer is to put data and raw materials into the 3D printer, and the machine will make the product layer by layer according to the program.

[0003] During 3D printing, the melted adhesive material releases a large amount of heat, so heat dissipation treatment is required in the 3D printer. In the existing 3D printer housing, one type of heat dissipation fan is generally installed on the top, and the wind enters from the material discharge opening on the side, resulting in limited heat dissipation effect on the printed part. Some other types of heat dissipation fans are installed at the bottom for exhaust. Similarly, due to the small airflow, the heat dissipation effect is also poor. In addition, the existing heat dissipation fans are directly installed on the surface of the housing, and the inlet and outlet air paths are horizontal or vertical, resulting in no need to directly contact the printed part or the print head assembly. Therefore, an improved technology is urgently needed to solve this problem existing in the prior art. Utility Model Content
