3D Printers: Make Whatever You Want


  • …14-year-old Riley Lewis and a few of his eighth grade friends…The boys can pretty much fabricate anything they can dream up on a machine called the RapMan.

  • The RapMan is a crude approximation of far more expensive and sophisticated prototyping machines used by corporations
  • …RapMan melts plastic (similar to that used in Legos) and then squirts it out of a movable nozzle in a controlled fashion.
  • For $1,299, anyone can now buy a 3D printer, hook it up to a Wi-Fi network, and begin downloading files that will turn into real objects.
