Cybernetics

3-D printing has taken printing to the next level with cybernetics. The Philadelphia Inquirer recently reported that “Princeton research creates a bionic ear.” “The scientist send bovine cells mixed in a liquid gel through the printer, followed by tiny particles of sliver.”  Once the ear is printed they put it in a petri dish and let it cultivate for 10 weeks. By then the ear changes its color to a flesh color. The is able to retrieve radio signals and turn it into sound. The end product is not to replace the human ear just yet. It is a stepping stone in the right direction. It shows the capabilities and limitations the 3-D printer can do. They were able to push the 3-D to a new level. Eventually in the future maybe will see organs and ears being rebuilt by 3-D printers. I think that they can push this idea and many more like this a lot further.
