A team of engineers from all over the world got together to create 3D printed prosthetics. Using the name Robohand, the team's focus was originally hands and fingers, but they are now working on an inexpensive 3D printed prosthetic leg.
Developers are currently using a 3D printer for the plastic parts, which are used together with metal rods and pneumatic pumps. In theory, this would allow people to order all the parts themselves online, or, better yet, allow hospitals to provide custom-fit prosthetics to amputees at a much lower cost.
It will still be a while before these Robolegs hit the market. Developers are working to make the fitting process better, and thorough testing is still needed.
The 3D printing is expected to make prosthetic legs much less expensive than what is currently available. A Robohand that is fully assembled costs around $500, whereas traditional prosthetics can cost upwards of $10,000.
