Cornell Researchers 3D Print a Working Speaker

As additive manufacturing (AM) further develops as an industry, it will continue to separate into various fields of production. Right now, medical applications for AM are developing at a rapid pace along one path, while other uses, such as parts production and rapid prototyping, are developing along another. Another major field that has really only begun to develop is AM-built electronics.

Researchers at Cornell University have embraced the challenges of 3D printed electronics and recently managed to produce a speaker built entirely using AM. A speaker is a fairly simple piece of technology, compared with more advanced electronic devices, and the challenge in designing one that could be built using AM required material engineering expertise to complement the 3D design.

3D Printing is the Vet’s New Best Friend

Like any good tool, additive manufacturing (AM) has a variety of uses. Beyond rapid prototyping and parts manufacturing, AM improves the lives of everyday people through its medical applications. Whether it’s a new ear or synthetic human tissue, 3D printing has become an important part of the health care field.

The technology doesn’t stop at helping humans, either. AM has helped out a duck with a malformed leg, an eagle without a beak, and probably many other feathered or furry patients I’ll never hear about. Along with building prosthetics, AM is used to treat animals in many of the same ways it helps human patients. Continue reading

Rapid Ready Roundup: State Department, Printers for Peace, Food and Star Trek

In the course of my diligent efforts to keep you good people up to date on the state of additive manufacturing (AM), I come across many interesting news items. I’ll gather them up every so often and present them in a Rapid Ready Roundup (like this one). You can find the last Roundup here.

If you follow AM news you’ll almost certainly be aware of the controversy surrounding Defense Distributed’s successful firing of a 3D printed firearm. The US State Department apparently heard about it as well and sent the company a takedown order, along with a suggestion the “Liberator” breaks international gun control laws. Continue reading

3D Printed Ear 2.0

I’m not sure what it is about ears and additive manufacturing (AM) that’s grabbed the attention of researchers, but apparently the two work well together. It wasn’t all that long ago that Rapid Ready reported on Cornell University’s bioprinted ear, and now Princeton University has performed the same feat, albeit with a different focus.

Where Cornell researchers were focused on creating a prosthetic for children who suffer from a congenital deformity, Princeton’s team has put its efforts toward battling hearing loss. Princeton’s ear was built using AM to combine biology and electronics. The result is a prosthetic that could not only boost a user’s hearing, but also allow him to pick up radio signals.

Cornell University Bioprints a Functional Ear

When William Shakespeare put the words, “Friends, Romans, countrymen, lend me your ears” in the mouth of Mark Anthony, he may well have been prophesizing the future. Additive manufacturing (AM) has been a natural fit for prosthetic development and manufacturing, and now Cornell University and the Weill Cornell Medical College have taken prosthetics research to a whole new level with a bioprinted ear.

While every prosthesis is designed to be functional (and some to have artistic merit), they are artificial replacements for living material. Not so with the ear developed by Dr. Jason Spector and Dr. Lawrence J. Bonassar. The bioprinting process uses living material to create a structure that remains alive after being implanted and becomes another functional biological part of the human body. Continue reading
