Doctors train on 3D printed hearts

My thoughts exactly. We will be able to produce better lab specimens than any lab animal could be. They would be easier to store and they would not need care like an animal would. For basic scientific reasons we could see and end to the practice of using lab animals.

I see the possibilities of meat alternatives as well. They could grow a type of animal tissue and then print it to have the texture and shape of meat. It would be a meat alternative that most people would like.

The possibilities are endless.
