Frequently Asked Questions

Are your files, manuals, and designs open source? Where can I find them?

Yes! We want passionate people as much as us about helping others to be able to do so. Please visit http://www.thingiverse.com/UCFArmory/about to see instructions for assembling the Gen 0 Limbitless Arm and downloading our files.

How do our limbs change kids’ lives?

The biggest change is confidence. After donning our bionic limbs, parents say their children seem more confident, more energetic, and less anxious about interacting with other people. Rather than their disability being a focus of jeering, they get excited questions and curious stares for their sleek bionic limb.

How long does it take to fabricate a bionic arm?

The time it takes to fabricate one of our bionic arms ranges depending on several factors, the most influential being the type of amputation. Our team currently has the experience to produce a helper hand in 4-6 weeks, and a bionic arm without an elbow in 8-12 weeks. Additionally, we are currently developing a bionic arm with an elbow, and starting the development of bionic legs both of which will expand the amount of people we can assist.

What is Limbitless Solutions?

Please visit our About Us page of our site for our full mission statement.

Simply put, we are a volunteer-driven organization of engineers, tinkerers, and developers of 3D printed bionic arms. We aim to knock down the barriers preventing those in need from having quality arm solutions by designing open-source 3D printed solutions and spreading a culture of innovation and sharing around the world!

How long will my child’s bionic arm last and how do replacements work?

While individual parts have a chance of breaking over extended periods of use, as a whole the bionic arm and its components should last at least a few years. The main factor in replacement is the child’s growth, as it is important for both balance and function that the bionic arm length matches that of a child’s natural limb. As such, a child will need to replace their bionic arm typically once a year. To print a new arm and hand comes to only about $70, and all internal components can be retained, all of which can be taken care of by the Limbitless Team.

What is the main goal of Limbitless Solutions?

Our goal is to develop solutions for children that are functional, affordable, and easy to manufacture. Due to their constant growth, children are often denied coverage by insurance companies and these solutions can be prohibitively expensive. By developing custom-made 3D printed bionic limbs for children with any type of amputation we can make sure they have the aid they need for a fraction of the cost.

What is 3D Hope?

3D Hope is our tagline, a small phrase that captures everything we are as an organization. This tagline is also short and easy to remember, so it will be incorporated into many of our marketing campaigns as a simple way to find our work! Through 3D printed bionics we try to give parents and children hope that someone cares about their needs and is working toward building them new tools to chase their dreams.

Do you only help kids who were born and/or live within the U.S.?

Our mission is to provide our Limbitless Arms to as many kids as possible all around the world. Our willingness to contribute in changing kids’ lives is limitless! If you know someone who could benefit from our help please contact us. Currently we have only accepted a few international cases, but hope in the future to be able to help even more.

What does bionic mean and what makes it bionic?

“Bionic” refers to an interaction between a technology and a person. Our designs are considered bionic because they are controlled directly by the child, with the EMG pads providing a direct control and interface for the arms.

Why do you primarily focus on children?

We chose to pursue the design and development for solutions specifically for children, because due to their fast rate of growth they would constantly outgrow typical aids and for this reason most insurance companies will not cover the cost. Additionally, the cost of this kind of aid is extremely high, so families would have to pay out of pocket almost yearly. By designing affordable and custom bionics we can give these families an inexpensive alternative so that their children can get the care and assistance they need.

What is the general process of making an arm?

To make an arm, a child is first measured (size of residual limb, length of limb, etc.) and the current model of the arm is then appropriately scaled. From there, minor tweaks to the design may be necessary to accommodate any features unique to that child’s condition, and then the arm is printed. From there the pieces are assembled and the electronics are wired together and set in place. Finally, the child must be fitted with the arm and an appropriate socket, and the EMG sensors are calibrated before the arm is ready for use.

How many people are involved in making a single arm?

Anywhere from 3-6 people are currently involved in the production of a single arm. This includes design, fabrication, assembly, and post-assembly processes such as painting or calibrating.

What is your Employer Identification Number (EIN) for tax purposes?

Our EIN is 47-1944657.
