The ‘exo-prosthetic leg’ created by Adam Root, is a 3D printed artificial limb that used modern technologies to fabricate the customizable, intimate, form-taking body part. 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 is made.
