Why do we need to be able to "print", that is, in essence, create human parts? Why not just rely on donors? Isn't that a more 'natural' way to deal with this issue of organ transplants?
Here is a great article on this, I think everyone in this group will really enjoy it: https://futurism.media/3d-bioprinting-is-the-future-of-transplants
My own take on this. We must remember that no technology works in isolation and is always dependent on other technological advances. As we know many breakthroughs in medical sciences is increasing the life expectancy of human beings thereby decreasing the availability of organ donors(it is a rather dark way to think of it, but it's true). Another, more unexpected avenue of research that would effect organ donations is self driving cars. As we know one of the major ways of fatalities is caused by road accidents, and the advent of self driving cars would reduce this by a great extent. Again, resulting in organ shortage. But this is of course no reason to be sad but quite the opposite. This is a reason why more effort needs to be placed on bioprinting, so when the need arises to tackle the shortage of organ donors, we already have a solution.
