Recently, a team of volunteers from the UK called e-NABLE presented an Unlimbited project to help people with disabilities on the elbow have fully customizable prostheses.
Looking at the world, there are many teams like e-NABLE to design a more personalized and functional perfect prosthesis for the disabled. E-NABLE's Stephen Davies and Drew Murray are two volunteers who want to make their lives better for people with disabilities, so they design and manufacture and hope to bring this project to the world.
“Since I joined e-NABLE, I have found that many people with disabilities have been waiting for a chance to get a prosthesis, perhaps because they can’t pay the fees, or because there are no prostheses that match themselves, and it’s always difficult.†Davies said, “I found that the number of prostheses available for children to choose from is very small, so it is difficult for them to choose the right prosthesis, so I started to design some 3D printed prostheses available to children, which are mainly elbow prostheses.â€
In fact, Davies himself is a flawed elbow. He has had 20 years of professional computer-aided design experience. After meeting Murray, they hit it off and decided to jointly design 3D printed prosthetics for people with elbow disabilities. Under their efforts, they designed the first 3D printing arm. It turns out that the prosthetics they designed are lighter, cheaper to make, and easy to print and install, which makes it affordable for most people. But at the same time, they know they still need to adjust their arms to various sizes because the children grow very fast.
In the end, after a few months of coding and testing their designs, they announced two versions of 3D printed prostheses. To get a perfect size 3D print arm, just pay attention to the key data of the length of the hand, the length of the forearm and the length of the upper arm, then enter it into the Thingiverse for customization, and then automatically generate a custom 3D printing arm with a precise ratio.
