A keen skier who was left paralysed from the waist down after an accident can now walk again, thanks to the world’s first 3D printed hybrid robotic exoskeleton suit. Three-dimensional printer makers 3D systems have been working with robotic exoskeleton maker Ekso Bionics to make a custom suit for test pilot Amanda Boxtel, who was paralysed in a fall on the slopes of Aspen, Colorado in 1992.
