The 3D printing hype has slowed down, and most people have now realized that a veritable desktop factory won't be the norm for everyone. However, some of the less eye-popping 3D printing applications, like industrial manufacturing and production and medical technology, are frequently overlooked. But the Human-Computer Interaction Institute (HCI) at Carnegie Mellon University (CMU) is working to change that. The US market for assistive devices rings in at just under $1 million: roughly 700,000 people have an upper limb amputation, and about 6.8 million other people have fine motor and/or arm dexterity limitations. CMU's assistive technologies project aims to develop more inexpensive methods of manufacturing and distributing these life-changing upper limb prosthetics for the people who need them most; one of those methods is obviously 3D printing.
