Global Debate of 3D Printing of Human Tissue?

[RedSox2013]

Ok, so we all know that eventually 3D Printing of Human tissue will become commonplace soon, however Gartner, known for their economic and social predictions, predicted that in 2018 3D printing of tissues and organs will provoke global debate.

What's the debate. If you can print human skin, a new kidney, a new liver or a new heart, how can anyone debate science going this route. Think about the lives this will save, and make better? Opinions?

EVERYTHING, no matter how beneficial, causes debate, and controversy.
