Scientists are close to being able to use 3D printers to make human organs!

Printing usable organs is something that sounds like science fiction, yet with recent scientific advances this is looking more and more like a reality. 3D printers have become increasingly common, and recently they have been used to create comfortable, personalized prosthetic limbs and hearing aids.

Bioprinters, however, use “bio-ink” which is made of living cell mixtures to form human tissue.
Today they can make basic tissue and human cells, which when laid layer upon layer form the tissue, but cannot yet form usable organs.

The hope is that one day the technology will become sophisticated enough to create organs that are identical to the ones that need replacement! In fact, the technology has also been promoted for potentially creating meat to solve hunger problems!
