Quite neat. Plays to the strengths of 3D printing
IE, making cavities and pockets inside objects
I had wondered about reading, but they are pinning that by imaging the object and looking at sub surface rather than sonar, which was my first thought.
BTW these pockets are meant to be in undetectable by eye as they are too small.
So potentially quite a useful addition to the 3D printing SOA.
Biting the hand that feeds IT
