A recent graduate from the University of Houston, David Edquilang, has developed an innovative 3D printable finger prosthesis named “Lunet.” Unlike traditional prostheses that can be costly and complex to assemble, Lunet is a promising solution that can be easily 3D printed and assembled without the need for metal fasteners, adhesives, or special tools.
The key motivation behind Lunet is to provide a low-cost alternative for amputees seeking to restore finger functionality. Standard finger prostheses often come with a hefty price tag, making them inaccessible to many. However, Edquilang aims to democratize access to this essential technology by making the design freely available on the internet.
“Not every good idea needs to be turned into a business. Sometimes, the best ideas just need to be put out there ,” said Edquilang, who graduated with a Bachelor of Science in Industrial Design last year.
“Medical insurance will often not cover the cost of a finger prosthesis, since it is not considered vital enough compared to an arm or leg. Making Lunet available online for free will allow it to help the greatest number of people.”
The success of Lunet lies in its simplicity and durability. Edquilang, with guidance from Associate Professor Jeff Feng, optimized the design through experimentation. By intentionally identifying weak points and making necessary adjustments, he achieved a more robust and functional prosthesis.
Lunet’s innovative design has not gone unnoticed. It recently received the prestigious 2023 Red Dot: Luminary award, affirming its impact on the field. This recognition underscores the potential for 3D printing to accelerate development in the prosthetic industry and improve the lives of amputees worldwide.
