A puppeteer and a carpenters have developed a RoboHand that has help a 170 kids with birth defects. The RoboHand can be printed on a 3-D printer for less than $150. The RoboHand can be easily reprinted in a larger size as the child grows. The plans are available on Thingiverse.

SpaceX shows a 3-D CAD tool interface that makes building in 3-D much easier and more efficient. Once a component has been designed, then the part can be fabricated with a 3-D metal printer. The printer deposites metal particles of Ti or Inconel and a laser then fuses them together. The part is build layer by layer.
