This 3D-printed prosthetic hand features a built-in space game

This Maker duo’s 3D-printed prosthetic hand is out of this world! 

Perhaps one of, if not, most amazing things to recently come from the 3D printing world has been DIY prosthetics. These artificial limbs have grown by leaps and bounds in the last couple of years. One group helping lead the way has been e-NABLE, a global network of volunteers who are using their 3D printers to create prosthetic hands for those in need. Given the initiative’s open source nature, prostheses can now be made for a fraction of the cost of their commercial counterparts.


One of the more popular e-NABLE models has been what’s called the “Cyborg Beast.” Using this as the base for their project, Maker duo Debbie and Danny Leung decided to develop an intergalactic-looking version of their own that boasts some additional functionality. Though it may work like other 3D-printed limbs, thanks to some modifications, an Arduino Nano (ATmega328) and a few other electronics, the Cosmogony brings an entertainment console right to the palm of a user’s hand.

The Cosmogony hand has two modes: display mode and play mode. In display mode, three rainbow diffused LED lights on the palm and four RGB LED lights in the fingertips repeatedly change colors. There’s also an Adafruit 8×8 dot matrix display connected to an accelerometer, which alters images as the wearer moves their hand. Aside from that, the prosthetic can be converted into a virtual video game that employs its embedded accelerometer.

In order to play “Expand Your Universe,” a user simply moves his or her hand in the direction that they’d like the characters to go. For this game, the main characters are actually four planets moving together at the center. As the wearer advances to each stage, an asteroid from a random direction comes closer. To avoid a collision, the user must try move their hand accordingly to dodge the asteroid in an X or Y direction sensed by the accelerometer.


“The blue lights blink in the fingertips, a smiley face appears, and they spread farther apart. To proceed to the next stage a player must successfully dodge asteroids sweeping across from random directions. If a player fails to dodge an asteroid, the red lights blink in the fingertips, a sad face appears, and the player has to start over at that last stage,” its creators explain.

The hand itself is comprised of flexible NinjaFlex filament, while springs were used for the finger joints. Six strings of fiber optic lights make up spiral shaped “galaxy” on the palm, which has a compartment for the LED dot matrix on top. Housed inside the gauntlet of the hand lies the Arduino, a 9V battery and a dual-axis accelerometer.

Pretty amazing, right? Watch it in action below!

7-year-old amputee gets a 3D-printed prosthetic hand

California girl receives a high-tech, 3D-printed prosthetic hand — for $50.

When Faith Lennox was nine months old, she lost her left forearm. Now at age seven, she has received a custom ‘robohand’ through the powers of 3D printing.

The easy-to-use prosthetic weighs only one-pound and cost the Lennox family $50 — merely a fraction of the price of traditional, sensor-laden pieces. What’s more, when Faith outgrows the prosthetic, whether it’s six months or two years from now, a replacement can be made just as inexpensively and easily as the first.

After trying numerous prosthetics throughout the years, Faith found them to be too bulky, heavy, and worst of all, difficult to use. And while on the search for a better alternative, her parents came across volunteer group e-NABLE, who has helped kids and adults seeking artificial limbs to build them through 3D printing. Currently, the non-profit organizations says that they’ve assisted nearly 1,000 hands for 700 families so far using their free, open-source design files. From there, the combination of experts from Cal State-Dominguez Hills, design studio Build It Workspace, and an Airwolf 3D printer brought the project to life.

The seven-year-old even had the opportunity to choose the colors and watch the printing process firsthand inside the Makerspace. Naturally, she would go on to pick a scheme of pink, blue and purple. What’s even more impressive is that the entire process took just about 24 hours. After slipping on the end product — comprised of 20 individually printed plastic pieces along with some metal screws and nuts — she was able to control it by simply moving her upper arm up and down.

And just like any kid her age would do, Faith took to her bike to test out her newly-crafted arm. It was a success! This example, among many others we’ve seen in recent weeks, demonstrates the limitless potential of 3D printers.

Video: 7-year-old boy receives a new prosthetic “trooper” arm

Add Stormtrooper to the growing list of comic book-inspired, 3D-printed prosthetics.

In recent months, we’ve come across quite a few miraculous and heartwarming 3D printing stories. And, it looks like that momentum is carrying on into 2015. The Maker Movement has now given a seven-year-old boy, who was born without part of his left arm, a pretty amazing 3D-printed Clone Trooper prosthetic.


First reported by the Augusta ChronicleLiam received his new limb as part of an international effort to harness new DIY tech to help those requiring prosthetics they otherwise couldn’t obtain. While commercial pieces can cost upwards of $40,000, more affordable options have been made available thanks to recent advancements in 3D printing. In addition to that, many insurance companies do not cover costly prostheses for children because they will quickly outgrow them; subsequently, 3DPs are a practical and feasible alternative.

After learning about E-Nable, a group of volunteers who print prosthetic parts for kids, Maker John Peterson decided to put his skills and acquired printer to go use by crafting a Star Wars-esque arm for the boy. It took the Maker nearly three months to create Liam’s new limb — for only $300.


A huge fan of the flick, Liam had spotted Imperial Stormtroopers marching toward him after leaving a Georgia movie theater. What he didn’t know was that the troopers were there to surprise him with a new 3D-printed prosthetic arm, which was paired with a Clone Trooper helmet and an invitation to join the 501st Legion.

Once Liam inserted it onto his left elbow, he was able to flex the fist and hold a cup. You’ll want to watch the entire surprise below!
