3D printing for artificial blood vessels In Pay the Printer, Philip K Dick imagined a species called “Printers” who could organically create perfect copies of complex objects. In this world, the increasingly-popular 3D printer can’t create a car, but its ability to produce simple 3D objects is being used to create blood vessels. The researchers, led by Fraunhofer’s …
It's a good advancement but my concern would be the residual plastic left in the blood stream after an artifical cell breaks down. Until the process can use fully organic and swiftly biodegradable plastics, I wouldn't feel happy about it being used in a transfusion.
However, if we're going to start speculating, this plastic blood could be used in things like replacement limbs, if you had some sort of membrane that could transfer oxygen from blood cells in the central body to the limb.
Another use could be the development of organic computers as a potential power source of some description, although the complexities of it would be way beyond my understanding.
