Two-year-old Sol with his fully-functioning Stratasys 3D printed hydraulic
prosthetic arm, which enables him to move his thumb on his own.

A hydraulic prosthetic arm was developed by Ambionics founder Ben Ryan for
his two-year-old son, using 3D printing technology from Stratasys. Ryan says
he used the Autodesk Fusion 360 during the design process as well as a
Stratasys Connex 3D Printer.

"Ben 3D printed flexible actuators and a power-splitting unit (double acting
helical bellow or DAHB) for the prosthetic," according to Business Wire. "The
DAHB unit enables the wearer to open and close the thumb in manual mode or
with assistive power (using compressed air or a hydraulic pump and
reservoir), but the grip continues to operate manually in the event of power
interruption."
