3-D printing is poised to change the world. The possibilities of these amazing printers are endless - especially in the medical world.

Already, we've seen 3-D printers create cyborg hands, replicate human organsfashion exoskeletal casts, and even create prosthetic limbs for animals.

Now, scientists are adding artificial blood vessels to that list. Though the technology isn't yet fully developed, scientists have developed a new process for making artificial tissues.

"Our approach involves the printing of agarose fibers that become the blood vessel channels. But what is unique about our approach is that the fiber templates we printed are strong enough that we can physically remove them to make the channels," said [Ali Khademhosseini, Ph.D., biomedical engineer] Khademhosseini. "This prevents having to dissolve these template layers, which may not be so good for the cells that are entrapped in the surrounding gel."

The process seems to be working, and the technology could be available in the very near future.
