The patient’s residual limb and remaining intact limb, if present, are first scanned to create a highly precise 3D virtual model, allowing the anatomy to match up within fractions of a millimeter.
During this process the Fit Socket technology, developed by the Biomechatronics lab at MIT, also captures leg tissue properties allowing a better fit – and therefore increased comfort – between the residual limb and socket.
His Exo-Prosthetic leg looks to modern technologies to streamline the manufacturing process.
By using a combination of 3D scanning, 3D printing and 3D modeling software, Root believes the entire process can be automated to create a customizable, affordable and beautiful product.
However, industrial designer William Root's Exo-Prosthetic leg also acknowledges the importance of beauty in prosthesis design.
Root believes the unaesthetic appearance of prosthetic limbs is the result of the flawed and outdated process of producing them.
Titanium dust particles are fused together using laser sintering.
Printed as a single 3D exoskeleton it is immediately ready for assembly.
The next stage will be to develop a fully functional prototype and determine the structural requirements. Root is considering how best to apply the new method to existing systems, and whether it would be most effective being taken up by a startup, a 3d-printing company or a big player in the existing prosthesis marketplace.
