An effort is underway to give individuality to people who have to use a computerized voice box to speak.
Just in the United States alone there are several million people who have lost their voice because of cerebral palsy, stroke, brain injury and more. If they are lucky enough to have a computerized voice chances are their voice sounds very similar to somebody else who also uses a computer.
GE Aviation has so much faith in 3D printing that it will soon relocate its Sharonville facility to a much larger space. GE bought what used to be called Morris Technologies in 2012. Morris was the first to introduce 3D metallic based technology to North America.
The technology works by taking a very fine grain metal powder and thinly layering it using a laser. This is different than taking solid material and subtracting it to make a part, like is done in machining.
