Prosthetic arms are generally classified into two main groups depending on their motion type: passive and active.
Although passive prostheses do not allow any active motion to be performed, they are crucial for stabilizing grasps, ensuring body symmetry, or providing cosmetic resemblance to users’ limbs.
On the contrary, active prostheses allow active motion control. They employ several control types, including body-powered (cables attached to a harness), electrical (switches or other control devices), myoelectric (residual limb muscular activation through electromyography sensors) and hybrid (by combining many of the control types) control types.
Imagine if Printables.com, Vogue Magazine and your local library forged the ultimate partnership to bring a creatively endless supply of prosthetics and adaptive devices to upper limb amputees. This is, in general what Haute Limbs seeks to build.
Humanity has never been as forward thinking in its technology, design and access to global communities than it is today. Yet, upper limb amputees around the world are still beholden to the power structures that prevent us from accessing basic functional needs.
Haute Limbs has the opportunity to not only remove those barriers to access, we have the opportunity to do it in a manner that brings art to everyday life in a way few medical device manufacturers even consider. For the more than over 15 million limb different people around the world, we think you are a worthy population to serve with creativity and excitement!
HISTORICALLY: Up until the US wars in Iraq and Afghanistan, upper limb prosthetic design had changed very little since the Victorian Era. As a female upper limb amputee, I could argue that the prosthetic designs for women during the Victorian era were comparably more feminine and beautiful in design.
MYO-ELECTRIC HANDS: With the dawn of myoelectric prosthetic offerings, it took nearly twenty years for women to be a consideration in basic hand size and only when a handful of companies saw the “market” was large enough to warrant the effort to build prosthetics made to mirror the female hand. Overall design is still non-existent outside of traditional socket customization.
3D PRINTED PROSTHETICS: 3D printing arrived with the promise of democratized, affordable and infinitely customizable upper limb prosthetics for the needing masses. Seventeen years later, we are no closer to that dream. Over ninety percent of 3D printed upper limb prosthetics one may see in the media or online are still not available for use or completely out of financial range for amputees, even in the US. The reasons vary greatly and are, to only a small degree from the perspective of an upper limb amputee, understandable.
Despite the low cost of materials, affordable 3D-printed upper limb prosthetics remain largely unavailable due to strict clinical requirements, the need for precise custom-fitting, and a lack of standardized medical reimbursement pathways.
The primary barriers limiting widespread access to 3D printed devices include:
-
Socket Fitting Complexity: The most complex and vital part of an upper-limb prosthesis is the socket (where the residual limb connects). A poorly fitted socket causes pain, skin breakdown, and eventual device rejection. This critical interface requires professional clinical evaluation, making it difficult to achieve a functional "plug-and-play" device directly from a home printer.
-
Durability and Structural Limitations: Upper-limb devices—especially those with myoelectric (muscle-controlled) components—undergo heavy daily wear and tear. Many inexpensive 3D printing materials (such as standard plastics) lack the necessary strength, leading to premature component breakage and mechanical failure.
-
Reimbursement and Insurance Gaps: The broader prosthetics industry relies on systemic policies and specific medical billing codes. Many 3D-printed devices lack the long-term clinical validation and regulatory clearance necessary to secure routine insurance coverage, leaving patients to pay out-of-pocket.
-
Regulatory Challenges: Unlike conventional medical devices that undergo stringent quality control and standardized testing, some open-source 3D-printed prosthetics lack clinical oversight. Organizations in the industry, such as Open Bionics, note that equitable access now depends on policy reform rather than technological advancements alone.
-
Lack of Customization and Training: To use advanced bionic 3D-printed arms effectively, patients often require physical therapy and occupational training. Because every user's residual limb is structurally different, these devices are difficult to mass-produce without customized CAD modeling by an experienced prosthetist.
On the spectrum of current 3D printed offerings for upper limb amputees and answers to all the reasons readily available manufacturing processes are not an option for upper limb amputees, we posit there are an innumerable set of helpful considerations not yet explored in between those two positions.
We have a vision to offer easily accessible, sizable, customizable and most importantly, fashionable prosthetic and cosmetic limbs and adaptive devices for anyone seeking an artistic alternative to life as an upper limb amputee.
