Printing Organs?

       As a bio major, I love anything weird. So when I read that 3D printers can print organs that can be actually used in the human body...I freaked out. Seriously. I thought that was the coolest thing in the entire world. Mainly, because a few years ago I had a debate on the organ donor's list, and the amount of people on that list is staggering; and, if the printers can make these organs, how well can they "mimic" the actual organ? Will transplants from other humans, and certain animals, even be necessary in the future? 
       Not only can the printers make organs, but they can also make hearing aids, dental implants, and prosthetic hands. So, these medical items are more in demand, and can be made quicker, and using less materials, does this mean that healthcare could become even more affordable? 
       In addition to making organs and body parts, it's said that food can also be produced, like that on Star Trek. It's interesting though, because I can't even imagine it actually being...edible. I think of it as just paper that looks like it's food. But it's not; but in reality, it is. This is such a hard concept to wrap my head around, that I probably won't believe it until I see it. If I ever do. 
       As for personal use of the 3D printers, I really don't think they'll be that popular. I think we'll see them more in hospitals, labs, and if the food printing catches on, maybe even fast food chains and restaurants. I also don't think I would want one for my personal use. Not really sure what I would use it for, but maybe for clothes or of the like.
