This new artificial limb is powered by rocket fuel. A team of mechanical engineers has created an prosthetic leg that is powered by a special type of liquid fuel called a monopropellant — the same kind of fuel that gives rockets their thrust. The new device could usher in the next generation of prosthetics — powerful and light-weight artificial limbs that will look and function more like the real thing.
Create Orthotics and Prosthetics launches first all-in-one medical-grade 3D printing system for prosthetics http://www.3ders.org/articles/20160919-create-orthotics-and-prosthetics-launches-all-in-one-medical-grade-3d-printer-for-prosthetics.html
An example of how 3D printing is making the world a better place. The Cortex cast prototype by designer Jake Evill heals fractured bones. The form of the cast varies with each case: 3-D scans are taken of the injury and used to determine the geometry and the distribution of the cast’s voronoi cells. The cells are denser in areas where the fracture is worse, requiring more support
