This project is about building a 3D printer for rapid prototyping. In contrast to a milling machine the process is additive i.e. the workpiece is built-up layer by layer, usually from thermoplastic material. Some commercial devices exists - needless to say, they are pricey. The goal of a RepRap machine is the ability to print almost all parts it consists of, hence ''a self-'''rep'''licating '''rap'''id prototyper''.

WTF?

This project is about building a 3D printer for rapid prototyping. In contrast to a milling machine the process is additive i.e. the workpiece is built-up layer by layer, usually from thermoplastic material. Some commercial devices exists - needless to say, they are pricey. The goal of a RepRap machine is the ability to print almost all parts it consists of, hence a self-replicating rapid prototyper.

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.

Status

  • 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.
  • First version of the extruder is resurrected from Bre's old parts and successfully extrudes HDPE.
  • We can print handcoded objects using a quick and dirty Arduino firmware.
  • Next step is to test a complete run from design to printed part. A lot of stuff will go wrong here, and the TODO list will depend on the outcome, but more work on the extruder is needed.

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
