August 5, 2014 Decatur – Wanda Oliveras (center) hugs Ty Esham as her family arrives at Esham’s office in Decatur on Tuesday, August 5, 2014. Robohand USA is a small company, run by Esham, who uses a 3d printer to make artificial replacement hands, mainly for children. These are much less costly than traditional prosthetics, whicih can run tens of thousands of dollars. Oliveras brought her 10-year-old granddaughter to be fitted with one of the devices.
