Open Bionics is a company creating prosthetics inspired by heroines, heroes and the fictional worlds they live in. The designs emblazoned on their first set of bionic hands include ones drawn from Queen Elsa from Disney’s Frozen, and Marvel’s Iron Man. The best thing about what they are doing is they offer you, dear reader, a chance to lend your own super powers of design and engineering. Open Bionics offers up 3D print files for several hand designs, hardware schematics and design files for their controller boards, firmware, and software to control the robotic hands with. Other than their website, you can also find all of the files and more on their GitHub account. If you’d like to devote a good amount of time and become a developer, they have a form to contact them through. To help with sourcing parts for your own build, they sell cables for tendons, muscle sensors, and fingertip grips in their online store.
We first came to learn about this company through a tipster [Dj Biohazard] who pointed to a post about their partnership with an 11-year-old Tilly, who is pictured on the left. Her bionic hand is an Open Bionics prototype whose design is based on the video game, Deus Ex. The best way products like these are improved are through the open source community and people like her.
Specific improvements Open Bionics state on their website are:
- The customised bionic arms are manufactured in under 24 hours and the revolutionary socket adjusts as the child grows.
- The bionic arms are light and small enough for those as young as eight.
- The bionic arms use myoelectric skin sensors to detect the user’s muscle movements, which can be used to control the hand and open and close the fingers.
Read more about Tilly’s story and her partnership with Open Bionic’s on Womanthology. Tilly seems to have a dream of her own to “make prosthetics a high fashion piece – something that amputees can be proud to wear.”
We at Hackaday have written about several open source prosthetic developments such as a five-day event S.T.E.A.M. Fabrikarium program taking place at Maker’s Asylum in Mumbai and the work of [Nicholas Huchet]. What superhuman inspired designs would you create?
It’s exciting how much 3D printing has enabled us to produce pretty much any shape for any purpose on the fly. Among the most thoughtful uses for the technology that we’ve seen are the many functioning and often beautiful prosthetics that not only succeed in restoring the use of a limb, but also deliver an air of style and self-expression to the wearer. The immediate nature of the technology allows for models to be designed and produced rapidly at a low-cost, which works excellently for growing children. [Pat Starace’s] Iron Man inspired 3D printed hand and forearm are a perfect example of such personality and expert engineering… with an added dash of hacker flair.
With over twenty years of experience in animatronics behind him, [Starace] expertly concealed all of the mechanical ligaments within the design of his arm, producing a streamline limb with all the nuance of lifelike gesture. It was important that the piece not only work, but give the wearer that appropriate super hero-like feeling while wearing it. He achieves this with all the bells and whistles hidden within the negative space of the forearm, which give the wearer an armory of tricks up their sleeve. Concealed in the plating, [Starace] uses an Arduino and accelerometer to animate different sets of LEDs as triggered by the hand’s position coupled with specific voice commands. Depending on what angle the wrist is bent at, the fingers will either curl into a fist and reveal hidden ‘lasers’ on the back of the hand, or spread open around a pulsing circle of light on the palm when thrust outward.
The project took [Starace] quite a bit of time to print all the individual parts; around two days worth of time. This however is still considered quick in comparison to the custom outfitting and production of traditional prosthetics… not to mention, the traditional stuff wouldn’t have LEDs. This piece has a noble cause, and is an exciting example of how 3D printing is adding a level of heroism to everyday life.
Thank you Julius for pointing out this awesome project to us!

Here’s a story that made us feel all warm and tingly on the inside. [Evan Kuester] is currently studying his Masters in Architecture with a specialty in digital fabrication. His program has access to some nice 3D printers, and he was itching for a good project to use them for. Why not a 3D printed prosthetic hand?
He got the idea after noticing a fellow student on campus who was missing her left hand, and did not have any kind of prosthetic. Eventually he worked up the nerve to introduce himself to her and explain his crazy idea. She thought it was brilliant.
Using Rhino, [Evan] began modeling the prosthetic hand using a plugin called Grashopper. He wanted the hand to be functional as well as aesthetically pleasing, so he spent quite a while working with [Ivania] to make it just right. His first prototype, the Ivania 1.0 wasn’t quite what he imagined, so he redesigned it to what you see above. It’s a beautiful mixture of engineering and art, but unfortunately the fingers don’t move — perhaps an improvement for version 3.0? Regardless of functionality, [Ivania] loves it.
Oh, and [Evan] and [Ivania] are close friends now — in case you were wondering.
