e-NABLE Prosthetics
Raiders for 3D Technology is a student run club at Texas Tech University focused on exploring solutions to medical issues through 3D printing. Partnered with e-NABLE, R3T modifies 3D hand prosthetics to fill the needs of our clients. As a hub in West Texas, we provide a low cost prosthetic limb that will enhance the experience for a person in need.
Scanning and Preparation
In order to get the best fit for our client, we create a 3D model of their arm using an iPad with a motion camera. This allows us to make custom fitted parts and get an idea of the sizing for the prosthetic hand.
Measuring and Modifications
Through feedback from our client, we create modifications to meet their desires and create a more personal product. From the Flash to Spiderman, we are able to draw inspiration and create a unique prosthetic limb.
Starting with a template, we can make changes to both the shape and pattern to create custom parts.
Assembly
Using 3D printing we can create custom and affordable prosthetic hands. Each consist of a variety of printed parts, wires, and cushioning foam.

How it works
This prosthetic hand is printed in parts and assembled to create a fully finished hand. Through a series of elastic wires and fishing line, the fingers are attached to tension pins on the back of the wrist gauntlet. With a bend in the wrist, the fingers on the hand will close together and create a grabbing motion. The tension pins on the back can be adjusted to allow different grip positions. After releasing the wrist bend, the fingers will go back to their initial state.
Fitting and Final Product
Flash Hand
Fall 2018
In the Fall of 2018, we created a prosthetic hand for Malakai. Through a series of 3D scans and measurements, we were able to design a prosthetic hand that would both fit the shape of his palm and allow full access to his thumb. Inspired by the Flash, Malakai's red and gold hand has brought on new possibilities and endless opportunities into his life.
Spiderman Hand
Spring 2018
Longing for the need of an e-NABLE location in West Texas, SivaTeja Pati and Sean Scully worked on a research project over 3D printed prosthetics. Their research would lead to helping out their first client, eight year old Toby, by printing a custom prosthetic hand. After creating a 3D scan of his arm, a pinch grip hand was created in the theme of Spiderman. Able to now fully grip and hold items, Toby has gotten to fully experience new things such as learning to play an instrument.
