After printing the model adhering to the platform, the bottom of the model has enlarged, which is a normal phenomenon. In order to ensure the adhesion of the model to the printing platform, a long bottom exposure time is required. However, excessive exposure time can cause the model to expand and lose dimensional accuracy. For more details, please refer to Common parameter description .
If high model accuracy is required, it is recommended to avoid this issue by printing the model in a suspended and tilted manner (without adhering to the platform).
