Although this was announced a few weeks ago, it seems to have been looked over by most media outlets. Perhaps because the prize is only $1 million. The Methuselah Foundation has announced that they are offering a $1 million prize for the first organization to successfully 3D Print out a functioning human Liver. It's called the New Organ Liver prize. Think you have what it takes to print out a human liver? Well here's the pdf about the prize

In my opinion the Xprize foundation should jump all over this and offer a larger prize, perhaps for a human heart!
