3D-Printed Exoskeleton Learns From Your Hand
This custom 3D-printed exoskeleton adapts to your hand shape, strength profile, and even your injury history.
(Exoskeleton 3d Printed)
The concept is deceptively simple: combine a precise 3D scan of your hand with parametric CAD design and selective laser sintering (SLS) to print an exoskeleton that matches your anatomy, not some average model. Every curve, joint angle, and finger length is taken into account...The real breakthrough lies in the exoskeleton’s artificial tendons, powered by a bidirectional stepper motor and shape memory alloy (SMA) wires. When heated, these wires contract with precision, translating thermal energy into controlled, repeatable motion. That means your device can fine-tune both force and range of motion for each finger independently...
As far as I know, the first use of the term exoskeleton was in A Specter is Haunting Texas by Fritz Leiber, published by Galaxy Publishing in 1968. This reference also has a half-dozen other exoskeleton articles attached.

The 3D-printed exoskeleton was created atGermany’s Fraunhofer Institute for Machine Tools and Forming Technology (IWU).
