AI Technical Summary
During 3D printing, especially when printing large items or long-term printing, the printed object is too large and the printing space is not directly connected to the outside world, resulting in poor heat dissipation and difficult to reduce temperature, which in turn affects the curing of the printing material, which may lead to deformation and unqualified products.
A 3D printer heat dissipation mechanism is designed, including two oppositely arranged housings, a built-in motor and a lead screw mechanism. The up and down reciprocating movement of the arc plate is realized through the folding mechanism, and the air is blown to the outer wall of the product through multiple exhaust holes to achieve a comprehensive cooling operation.
This heat dissipation mechanism can effectively reduce the temperature of the printed object, improve the heat dissipation effect and efficiency, avoid deformation problems caused by excessive temperature, and ensure the quality of the printed product. At the same time, the heat dissipation end can be folded and stored to avoid affecting the printing operation and has a wider range of applications.

Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of 3D printers, in particular to a heat dissipation mechanism of a 3D printer. Background Art
[0002] 3D printing has been a very hot topic in recent years. With 3D printers, people can easily make the designed objects. In the past, product production usually required making molds first, and then pouring and other processes. The production of molds is very expensive, and once a mistake is made, it will bring a lot of losses. 3D printing can directly print out the finished model without the need to make molds, which can save a lot of time and energy.
[0003] 3D printing melts the material by heating it, sprays it out through a nozzle, and then cools it down to solidify it. However, when printing some large objects or printing for a long time, the printed object itself is too large to dissipate heat well, and the printing space is usually not directly connected to the outside space, and the air flow is poor. As a result, when the printed model exchanges heat with the air, the air that absorbs heat cannot be quickly dispersed by flowing, so that the temperature of the object cannot be reduced. The high temperature makes it impossible for the printed material to solidify, and it is easy for the object to deform, resulting in unqualified printed products. Utility Model Content
