After seing Vik's presentation about how to build a RepRap we've started our own implementation of a RepRap. Then Bre Pettis came by in November 2007 and decided to build a McWire-based RepRap for Roboexotica. In a week. Metalab inherited Bre's RepRap (yay!) and it's now used as a basis for our own RepRap.


Note: At the moment, what we're building is really a RepStrap.


  • Parts ordered from the RepRap Research Foundation for XYZ axis and extruder boards.
  • XYZ axis is working.
  • We can now also control our CNC machine from the RepRap software using a modified Arduino firmware and a CNC Arduino shield.
  • Next step is to experiment with and build an extruder

Materials in the Lab

  • Two glasses CAPA/Polymorph -> went missing after the camp?
  • A roll of HDPE
  • All necessary boards, electronics and plastic parts for the RepRap and some spare parts
