Wow, this was impressive! After milling, the remnant of the block always has fins, or they break off. But, this one was unbelievable!
The fin was measured at 0.10mm! It was so thin, that the “3M ESPE” letters could be seen on the other side of it! In fact, it looked like the letters were thicker than the material!
It is hard to deny the ability of our materials to be milled!
