3D printers are becoming one of the great hopes for the world of medicine. Imagine here print parts of your body that you need them as easily as you get parts for your car. So far we obtained some successes in this regard and the last one can contemplate in the image below: an ear made with a 3D printer looks like a real human ear.
The ear has been achieved combining information technology and bioengineering, ie consists of organic material, even when you know the details of the feeling perhaps that the invention is less attractive than it appeared. The invention in question operates in this manner: first scanning is performed digitized patient's ear that is to be replicated or digitally drawn using an appropriate software. Once you design a mold is achieved thanks to the 3D printer.
The mold is filled with a collagen based substance obtained from cells found in rat tails (this is the strangest part of all, because you just might say a 'rat ear' attached to the head) and millions cartilage cells obtained from a cow. Finally it bathe all in a nutrient substance for cell culture grow and adapt to the shape of the mold.
Scientists say it takes half a day in the mold design, print a day, 30 minutes to inject the gel solution and 15 minutes later you have the ear list. Hopefully will get similar techniques to get other body organs.
