Design engineer, Jamie brought his 3D printer into class.  He showed us how he translates a solid object into a program, which can then be loaded into the printer.  The machine melts a reel of plastic and lays it onto a glass plate in sections – building up one row at a time.  This little plastic robot took about 30 minutes to print, but the robotic hand was our favourite.  Jamie has left us a design challenge to work on over the next week.
