Description

Technical Field

[0001] The present application relates to the field of 3D printing light curing, and in particular to a 3D printing light curing component. Background Art

[0002] 3D printing light-curing components are used to cure the part after the printing process is complete. Although the part has solidified, many internal parts are still not fully cured. Furthermore, during the subsequent cleaning process, the cleaning solvent will soften the part. Therefore, the part needs to be re-cured to quickly improve the overall hardness of the part and the bonding between internal layers to meet quality requirements.

[0003] For example, Publication No. 201921571190.7 discloses a light-curing 3D printing device, comprising a resin pool, a printing substrate, a lifting mechanism, a flexible transparent bottom, a scraper, a light source device, and a light source displacement device. The light source device is located below the resin pool, and the flexible transparent bottom is provided at the bottom of the resin pool. However, in actual use, the device still suffers from the following deficiencies:

[0004] When the light-curing 3D printing device of the above-mentioned patent is actually used, the light source can only be displaced horizontally and cannot be adjusted in height by itself, resulting in many blind spots in the light curing process. This may lead to uneven light intensity at the same height in the curing area, resulting in inconsistent curing effects. Some areas may not be fully cured due to insufficient light, and the heat is always concentrated at one point, which may cause local overheating and affect the performance of the material and the curing effect.
