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.

  • I think it’s a marvelous idea. It took long enough. It doesn’t look as bulky- heavy as the old ones.

  • the right structure will support everything – but looking at natural structures like that where you have to handle both pulling and pushing forces, I always see smooth crossing design (radius etc.) so that there will be no notching effekt with aprupt structur changes. This here looks like sticks brought togehter and not so much like a grown structure.
    Wouldn’t that help to reduce material and weight even further?

  • If you had bothered to read the article properly you would know that this was engineered NOT to need your stupidly heavy steel pins
    I hate people who negative comment a new concept trying to appear smart

  • Very cool idea! But I think it should have a metal bar in the middle, for proper support, I doubt the 3d printed structure would withstand the weight and constant impacts of walking, running and so on. That´s why we have vertical straight bones, because they withstand much better the stress of walking, running, etc etc.
    But the idea is awesome, I can imagine with a metal chromed bar in the middle, reflecting all the beautiful 3d printed outside structure.
