Description

Technical Field

[0001] The utility model relates to the technical field of UV curing, and more specifically, it relates to a UV curing device for 3D printed products. Background Technique

[0002] A UV curing device for 3D printed products is a device used in processes such as stereolithography or digital light processing in 3D printing technology. Its main function is to use external means to cure photosensitive resin materials, thereby constructing three-dimensional objects layer by layer.

[0003] In the existing technology, firstly, some devices for 3D printed products will not be able to obtain the necessary drying treatment, which may lead to incomplete curing of the products, affecting product quality. The hot air may not be evenly distributed, resulting in uneven heating of the products, causing deformation or stress. Manual or non-automated drying methods will reduce production efficiency, increase operation time and costs. Secondly, some drying boxes of the devices may not be able to be stably fixed during the curing process, affecting the curing effect. Without precise snap-in positioning, the air outlet may shift during the curing process, affecting product quality. Finally, manual or non-automated snap-in methods of some devices will reduce operation efficiency, increase labor intensity, and affect the accuracy of curing. Content of the Utility Model
