Description

Technical Field

[0001] The utility model belongs to the technical field of 3D printing, and in particular relates to a light-curing 3D printing model post-processing device. Background Art

[0002] Models printed by light-curing 3D printing usually need to be post-processed before they can be used better. One common post-processing method is to use post-processing equipment to perform secondary curing on the model. This process aims to enhance the performance of the material and make the model more suitable for coloring, use, etc. Generally, the curing quality of the post-processing equipment depends on the uniformity and energy intensity of the light source.

[0003] At present, the common post-processing equipment on the market uses a curing lamp with a turntable. The curing lamp is usually placed in the middle of the post-processing equipment, and the turntable drives the model to rotate so that all sides can be illuminated, thereby achieving the effect of secondary curing; however, since there are dead corners at the bottom of the model that cannot be illuminated by light, some post-processing equipment will add additional lamp beads at the bottom to allow the bottom of the model to be cured, thereby improving the overall curing effect; and some post-processing equipment does not use a turntable, and curing lamps are added around the equipment, and the number of lamps is increased to create a more uniform lighting area to achieve the design purpose.

[0004] The current solution has great flaws. Whether adding lamp groups at the bottom or increasing the number of lamp beads around, it will lead to increased energy consumption. More energy is needed to drive these additional lamp beads and lamp groups, which not only increases operating costs, but may also have a certain impact on the environment. At the same time, increasing the number of curing lamps means that the equipment will be more complicated, increasing the difficulty of repair and maintenance. In addition, the overall life of the lamp may also be affected, requiring more frequent repairs and replacements. Although increasing the number of curing lamps can improve the uniformity of lighting, there are still some bottom areas that cannot be fully illuminated, which can easily lead to uneven curing effects and affect the quality of the final product. At present, there is a lack of a new type of light-curing 3D printing model post-processing equipment to ensure the uniformity of irradiation, ensure that the bottom of the model can be evenly irradiated, and improve the overall curing quality of the model.

[0005] Therefore, a new technology is needed to solve the problem of lack of a new type of light-curing 3D printing model post-processing equipment in the prior art. Utility Model Content
