3D printing may hold the key to cure deafness

Revolutionary 3D printing technology may offer the key to helping deaf people to hear, without the need for hearing aids. Experts can now craft replacement parts for fragile bones, known as ossicles, which transmit external soundwaves towards the cochlear nerve. The researchers hope that these personalised devices could soon make hearing aids a thing of the past. Revolutionary 3D printing technology may offer the key to helping deaf people to hear, without the need for hearing aids. The researchers removed the ossicles from three dead bodies and took a CT scan to get specific measurements. They then used a 3D printer to create replicas to replace the bones they had removed.
