I don't believe ordinary balls would experience the same level of degradation simply because the pressurized air inside is most of what makes it bounce

I've had basketballs fail. Suddenly your ball has a lump. Happens after a hard hit sometimes.

On the 3D printed one, I'd assume the opposite problem. A hard hit causes a dead spot or actual indent.

Both make it hard to play with.
