Doctors train on 3D printed hearts

[Catherine]

I am hoping 3D printed tissue can be used in place of most lab animals. Certainly for dissection/training the 3D material would be better than a lab animal.

We could see a world where animals are not used in labs.

Who knows, if they can grow animal protein in the lab, they could 3D print "meat". It could look and taste the same and we could stop factory farming.

If we choose to look for alternatives, we can end animal cruelty.
