Printing machines have been around for a long time.  In 2000 bioprinting was thought of and starting to be developed.  Now bioprinting works and is at the stage of testing on mice.  Their goal is to start human clinical trials in the next couple of years.  Bioprinting works similar to an ink printer, only instead of ink, human cells are placed in the cartridge.  The human cells are "printed" out in a pattern.  Scientist can make tissue, organs, and even bones using this technology.  Below is a very basic diagram showing how bioprinting works.





Below is a link to a video on CNN website giving some incite on what bioprinting is and the man who started this.

When I first heard about bioprinting I was very skeptical and didn't like the idea of it.  Now, knowing all the good that it can accomplish, my stance on the subject is changing.  But now I ask you all, do you see anything bad with bioprinting?  Do you see any problems or ethical issues arising from this?
