Scientists trying to build functional human heart with 3-D printer
It may sound far-fetched, but scientists are attempting to build a human heart with a 3-D printer. Ultimately, the goal is to create a new heart for a patient with their own cells that could be transplanted. It is an ambitious project to first, make a heart and then get it to work in a patient, and it could be years — perhaps decades — before a 3-D printed heart would ever be put in a person. The technology , though, is not all that futuristic: Researchers have already used 3-D printers to make splints, valves and even a human ear.
