The 3D printer printed a human ear

A group of young engineers and scientists from Princeton University located in the United States, Princeton (new Jersey), shocked his new invention all the world's medical fraternity: they were able to print on modern 3D printer artificial human ear that can hear.

3D-ear

Developed a prosthesis that looks a little different from this ear, called the Bionic Ear, it has a special hearing aid, and is an indispensable thing for those who for some reason was deprived of its native ear, as with the loss of the body is lost and the ability to hear.

3D-printer

3D printer - truly can be called one of the most unique inventions of the 21st century, because it can be used not just to print virtually any three-dimensional form and products, and create the perfect dentures lost human organs. Perhaps in the near future, these technologies will allow physicians not only to produce the prosthesis, but also to restore amputated limbs.

Prosthetic Bionic Ear

American researchers have managed to create the world's first bio-implant of the human ear, which combines both artificial materials and animal by-products, which was published in the scientific journal Nano Letters, where the team, led by Michael MacAlpine put the results of their work.

Bio-implant of the human ear

When the Bionic Ear by scientists from Princeton University used the hydrogel as the base material for printing the matrix), silver nanoparticles, multiple conductors, and these cells calf. It is these living cells in the interaction with the human body turn into natural cartilage, which is an artificial bio-ear is attached to the human skull, allowing the carrier to enjoy the real stereo sound the real world.

Bio-ear allows you to hear sounds

This method of integration of the implant with the human body allows you to get a much more sound sensations from the artificial ear than from a simple hearing aid. Prosthetic the Bionic Ear has extremely high sensitivity, frequency range, allowing to capture not only the standard for human hearing 20Hz-20kHz upper bound of the range more than 1 MHz, but the frequencies we are no longer available for perception.

Bio-man, soon

The obvious advantage of printing with bio-materials on a 3D printer is the ability of an individual approach to each case, you're not going to argue that we all have ears (in the form) is different, so creating individual matrices and prints the finished product is an important component of the final result.
