3D bioprinted heart provides new tool for surgeons

One of the things most amazing about the world is that the activity of human beings spans such a wide range of behavior: we do things that are so stupid that an alien might think we are not even sentient, and then we're capable of doing stuff in science and engineering that is absolutely brilliant.

Wow, this is so cool!

My girlfriend is a cardiac surgeon and tinkers with 3D models & printing. She has a baby project - a library of anatomical heart models, depicting various defects. https://3dhearter.com/
