I looked at the article: New bio-printing technique makes blood vessels in 3D-printed organs possible.
I think 3D printing is an exciting thing. Being able to manufacture complex objects rapidly and at low cost has so many possibilities, but I had no idea that it was possible to 3D print human organs! I think it will be really interesting to see where this technology takes us in the future.
