AI Technical Summary
Technical Problem
In the 3D printing process, the unified exposure control method of the support structure model and the main body model in the existing technology makes it difficult to remove the support structure, affecting the integrity of the main body model.
Method used
By distinguishing between the main model and the supporting model, different exposure energies are used to precisely expose each area, ensuring that the supporting structure can be easily removed after printing without affecting the integrity of the main model.
Benefits of technology
The supporting structure was successfully removed without affecting the integrity of the main model, while ensuring the stability of the main model during the printing process.

Abstract
This disclosure relates to an exposure control method and a 3D printing device, addressing the technical problem of significant difficulty in removing the support structure model after printing, which severely affects the integrity of the main model. The method includes: acquiring main model data and support model data of model slices; the main model data includes a first region occupied by the main model, and the support model data includes a second region occupied by the support model; fusing the main model data and support model data based on the overlap between the first and second regions to obtain fused data; the fused data includes a first target region and a second target region; exposing the printing material of the first target region to a first exposure energy, and exposing the printing material of the second target region to a second exposure energy.
