Cracking

Cracking of parts occurs

Post-treatment: alcohol is not completely cleaned inside the hollow or external residual resin, resulting in reaction and deformation, for the hollow parts， you should try to increase the internal cleaning time; cleaning is not done after the completion of post-curing or curing time is too long, cleaning is recommended immediately after the low medium light intensity curing for a few minutes, conditions can be done to the hollow internal curing to improve the strength and prevent the impact of moisture factors

Model: model hollow wall thickness is too thin (<3mm), the strength is not enough, the wall thickness should try to increase the wall thickness, while increasing the internal filling density

Slicing: insufficient exposure time, so that the model is not cured enough
