How is 3D printing changing the future of prosthetic and animatronic limbs? 17-year old inventor Easton LaChappelle from Colorado, built a prosthetic arm by generating most of the parts through a 3D printer.

"My goal is to create an affordable prosthetic for everyday use," said LaChapelle.

When he was 14, he came up with an idea to built a robotic hand out of Lego bricks, fishing wire and servos. It was a challenge because he knew nothing about electronics or programming. But that idea triggered him to learn himself electronics and modeling software. The first version of robotic hands won him the 3rd place at the Colorado state science fair in 2011.

The second version of the hand grew into an arm. Using an open source hand from Thingiverse and help of a Makerbot 3D printer, LaChappelle was able to upgrade his animatronic gripper to a functional robotic arm with more 3D printed parts.

At the Colorado fair he met a little girl who was born without a right arm and wore an $80,000 prosthetic limb, and he was convinced he could do better.

Now 17, LaChappelle has completed the third version of his robotic hand and the costs is only around $250. His 'Arduino Robotic Arm' is up to shoulder and has the same functionality as a human arm. It connects to a brainwave headset that read the user's brainwaves and get a focus rate, so when the user focuses on an object the hand will close and grasp an object. And the arm also has a feedback system using a force sensor and a vibrating motor to give the user a sense of touch.

This affordable prosthetic arm opens a lot of applications and is the perfect platform to change peoples life. Heineken recognized his creation and asked LaChapelle to produce about 5,000 pieces of his robotic arm for their bars to serve beers to their customers.

Currently LaChappelle is working as an internship at NASA. Watch here LaChappelle discusses about his invention and how 3D printing helps him in the building process of a robo-arm in this TEDx Talk.

Easton. ......wow, am I impressed! I'm 51 -year-old with a complete spinal cord injury, my level of injury is C 5-6 which left me a quadriplegic I love your ideas especially like that it's wireless! I used to teach full tome before my accident and get excited when I see students like you. You obviously have a gift and need to continue sharing this wonderful item! I'm sure many people have faith you can change their lives and I'm definitely one of them! I heard you mention in your videos these prosthetic available for free? I'd like to try one if possible and would love to donate the $400 to your organization for further studies. Please let me know how I can go about and do that.
