3D printing and prosthetics have turned out to be a winning combination. In the latest match-up showcasing the power of the technology for solving a growing health issue, Autodesk has teamed up with the Enable Community Foundation (ECF) and Voodoo Manufacturing to conduct what they say is the world’s first global hand drive for 3D printed hands.
As part of the global hand drive, 22,000 individual hand parts were assembled into 750 prosthetic hands. Image Courtesy of AutodeskFirst, some background on the trio of players. ECF is an international network of volunteers committed to leveraging 3D printing technology and STEM programs to create affordable prosthetic devices to serve children and underserved populations around the globe. Autodesk, a giant in the 3D modeling software world, sponsors a community impact program through which it encourages its employees to give back by contributing time and money to good causes. Voodoo Manufacturing is a Brooklyn-based 3D printing services company formed by ex-Makerbot employees, which touts its digital factory approach as a reliable, low-cost method for limited run manufacturing.
The problem the trio set out to solve is giant. In the United States alone, there are nearly 2 million people living with limb loss, according to the Amputee Coalition. The CDC estimates that about 1,500 children are born with congenital upper limb deficiencies every year and 32,500 U.S. kids deal with an amputation due to trauma or disease.
For their recent hand drive, the players came together to design and create 750 printed hands distributed to kids around the globe at a cost of less than $50 per hand. Unlike traditional prosthetics that cost tens of thousands of dollars and can take several weeks or months to produce, these low-cost hands were made of 22,000 individual parts, printed at the Voodoo Manufacturing digital factory over the course of a month and assembled by 10,000 Autodesk employees spread across offices throughout the world.
Autodesk employees around the world participated in a 3D printed hand drive.

ECF has traditionally relied on its community to manufacture the parts for the prostheses, an approach that made it difficult to maintain consistency and quality, he explains. “They have a product that’s incredible, and we have a cheaper and more widely accessible way to produce the parts in bulk,” he says.
Unlike 3D printing services bureaus that operate with a handful of really high-end printers, Voodoo’s approach is to leverage 160 Makerbot Replicator2 units working in concert simultaneously to perform a print job.
The team enlisted Voodoo Manufacturing’s digital factory, composed of approximately 160 3D printers, in the hand drive effort.

Schwartz says the bulk of Voodoo’s customers fall into two buckets: Those creating brand-specific runs of promotional giveaways and engineering organizations looking for an alternative approach for making lower-volume parts or small-batch runs for prototypes.
Schwartz says the company will continue involvement with ECF and says its 3D printing approach is just what the organization needs to ensure quality and scale. “Before they had to try to find companies or individuals who had 3D printers and round them up to produce any number of the hands they wanted to send to children,” he says. “It was a match made in heaven.”
