Prosthetic arms can cost $3,000-$30,000, which may be prohibitive for patients in developing countries or for parents of children who can outgrow a prosthetic each year. Dremel, a business unit of Bosch Power Tools division, has helped high school students find a solution. Equipped with a Dremel 3D Idea Builder printer, members of Novi High School’s FIRST Robotics team are learning about 3D printing and creating prosthetics for their Helping Hands project. The students have built and donated 75 hands through their partnership with e-NABLE, a global network of volunteers using 3D printing to provide free prosthetic hands for those in need. These prosthetics cost $20-$50 to make and are durable enough for daily use. In addition to providing affordable prosthetics, the Helping Hands project focuses on education by teaching neighboring schools and communities how to print and assemble prosthetics.
