3D Printing Prosthetics
From: Digital Engineering - 05/2017 -page 17

Ambionics was launched by Ben Ryan of the UK, confronting the need for a
“training” prosthetics for the under-two-years-old age group. Inspired by his
own son's needs, Ryan, a psychologist/ teacher, not an engineer, designed and
developed a novel, pint-sized hydraulic prosthetic that uses a double-acting
helical bellow to allow opening and closing a thumb. He tested the lower-arm
concept in foam then 3D-printed it on a Stratasys Connex system.
