Description

Technical Field

[0001] The utility model relates to the technical field of 3D printers, in particular to a 3D printer with a cooling structure. Background Art

[0002] 3D printing is a type of rapid prototyping technology, also known as additive manufacturing. It is a technology that uses digital model files as the basis and uses adhesive materials such as powdered metal or plastic to construct objects by printing layer by layer. 3D printing is usually achieved using a digital technology material printer, which is a 3D printer.

[0003] For example, the Chinese utility model patent with application number: 202121366849.2 discloses an energy-saving 3D printer with a cooling function, which relates to the technical field of 3D printers. It includes a frame, a first linear module is installed on the inner bottom of the frame, and a printing table is installed on the slide of the first linear module, a semiconductor refrigerator and a workpiece exhaust fan are installed on the upper and lower surfaces of the printing table respectively, a second linear module is installed on the inner side wall of the frame, and a third linear module is installed on the slide of the second linear module, and a nozzle assembly is installed on the slide of the third linear module. This energy-saving 3D printer with a cooling function uses a semiconductor refrigerator to cool the printing table surface of the molding material, and the workpiece exhaust fan draws part of the cold air on the table surface upward, so that the molding material is filled with cold air around it, so that it can be quickly cooled down. At the same time, the turbine fan in the nozzle assembly cools the discharge nozzle to a certain extent under the drainage of the air guide cover, thereby extending the service life.

[0004] When the device in the above patent is in use, although it can cool down the nozzle by blowing cold air under the action of the turbo fan, the temperature at the nozzle of the 3D printer is relatively high during use, and the overall heat dissipation effect is poor when a single fan is used to cool the nozzle of the 3D printer, thereby reducing the service life of the nozzle.
