A Look Back At A 3D Printed Limb.

This may not be people’s first time seeing this 3D printed exo-prosthetic leg.  But it sure is remarkable enough to take a look back at.  The ‘exo-prosthetic leg’ was created by Adam Root, this 3D printed artificial limb uses modern technologies to fabricate its customizable, intimate, form-taking design to fit the leg. Developed to resolve the time intensive, costly and tedious current process of adapting a prosthesis to an amputee’s specific anatomy, this design enhances a combination of a 3D scanner, printer and modeling software in order to create a more precise and affordable manufacturing procedure.

Scanning technologies such as an inverted laser, form a highly precise virtual model of the patient’s residual limb and matches its anatomy to within a fraction of a millimeter. This, as well as the MIT biomechatronics lab developed fitsocket that captures leg tissue properties to enable a better fit, is then ready for 3D software modeling. All this information is combined in a custom-patterned mesh model and is hollowed out into an exo-skeleton, to reduce weight. By fusing together titanium dust particles in a laser sintering process, an extremely durable, lightweight and biocompatible prosthetic limb.
