Printed object detached from supports
If the printed object detaches from supports mid-print, it usually falls into the resin tank, while the supports are still attached to the printing platform. It’s usually caused by the combination of the printed object’s weight and insufficient supports. Another possibility is that you are printing a hollow object without drainage holes – this creates suction on the bottom of the tank and the object cannot detach properly.
Consider using Meshmixer to hollow out the object. Too heavy (solid) objects may be too much for default supports and as a result, they often detach from supports once they reach a certain weight threshold.
Solution: Increase the number of supports or the thickness of supports. Check the exposure times and change them to recommended values.
