how to avoid the material of overhang inner surface dropping

Recommended Posts

When I print overhangs of an object, no matter large or small, the inner surface of the overhang part is always ugly, my guess is the material is slowly dropping because there is no support.

How to avoid this and print a beautiful inner surface for overhang?
