Princeton University researchers created synthetic ears that can not only receive sound, but transmit them. The scientists mixed with the help of a 3D printer bovine cells with a liquid gel and tiny particles of silver. The printer was scheduled to use the material and give shape to a ‘Bionic Ear’ and take the silver particles to create an antenna coil. This antenna to capture radio signals that the ear will be interpreted as sounds.

Feathered Angels Waterfowl Sanctuary, an organization specialized in the protection of animals, availed herself of a 3D printer to produce a prosthesis that helped a duck named Buttercup to walk again. The duck had a crooked legs and was impossible to walk without pain. The members of this Organization cut off the tip of the duck and developed a prosthesis created with silicone in a 3D printer.

American doctors used particles of plastic and a 3-d laser printer to create a trachea and to save the life of Kaiba Gionfriddo, a boy who used to stop breathing almost every day.

A Carpenter and a special effects artist came together to give life to a mechanism that is helping children who lost fingers or were born without them to recover all the mobility of your hands using printers in 3D. They designed a prosthetic hand that can be printed by parts in 3D.

The Defense Distributed group, who believes that everyone has the right to possess a firearm, produced the first weapon in the world with a 3D printer. It was realizadao with a machine of US$ 8,000, which prints each component based on layers of plastic.

Briton Eric Moger became an example of the application that can have on medicine 3D printers. Doctors used a printer to rebuild parts of the skull were removed during an operation to remove a tumor.
