3D printed bionic ear: can receive and transmit sound

3D printing is becoming more and more mature, and applications are increasing. Some time ago, OFweek3D printing network once reported the news of Shenzhen Hospital for patients to print their ears in 3D. Today, a university in the United States uses a 3D printer and bovine cells to create a bionic human ear that can receive and transmit sound.

The technique is to feed the gelatinous liquid with bovine cells and tiny silver particles into the printer. The printer is specially programmed to shape these materials into bionic ears and shape the silver into a spiral antenna.

These antennas can receive radio waves, which can then be converted into sound signals by bionic ears.

Most Tattoo Needles(tattoo sterilized needles) are made of some grade of stainless steel. Surgical stainless steel

is very common in tattooing needles. There are four main types of needle groupings. Some have one

specific use and others can vary depending on how the artist is using it. Tattoo Needles that we carry

are pre-sterilized in individual blister packs. We carry tattoo round liner needles (tight), tattoo round

shader needles (loose), and tattoo curved magnum needles. Our professional tattoo needles are used

by professional tattoo artists around the world and are highly recommended. Below is a general

explanation of the needle categories and how you can use different types of needles.
