From reprap.org:
- RepRap is short for Replicating Rapid-prototyper. It is the practical self-copying 3D printer shown on the right - a self-replicating machine. This 3D printer builds the parts up in layers of plastic. This technology already exists, but the cheapest commercial machine would cost you about €30,000. And it isn't even designed so that it can make itself. So what the RepRap team are doing is to develop and to give away the designs for a much cheaper machine with the novel capability of being able to self-copy (material costs are about €500).
The RepRap project is a bit optimistic in their description -- their "self-replicating" machine is capable of printing all of the non-commodity parts of their machine, but still needs stepper motors, steel rods, screws, nuts, control circuitry, and of course a human to assemble the pieces.

Participants
Plan
- decide what system to build
- Print head
- Chassis
- what design? (lasercut acrylic, plywood + steel rod, ...)
- The McWire
- Electronics
- control electronics design (something better than "one Arduino to rule them all" please)
- Stepper Motors
- we need 4 stepper motors conforming to the following specs:
- NEMA 23 size, bipolar, about 100 oz-in torque, dual-output shaft
- we need 4 stepper motors conforming to the following specs:
- purchase parts
- * Consult the McWire BOM for what to buy
- build it!
Some parts of RepRap can be developed independently. In particular, the Extruder "print head" is pretty much independent of the chassis mechanism, and looks like a fun project. Might want to consider other print mechanisms too; this one may be specific to a few of the thermoplastics.
Status
- TurksHead has started building a McWire chassis. (10/22)
- adi is researching print materials and print heads. (10/23)
- adi has ordered components and PCBs for the following boards: (10/29)
- had a RepRap Soldering Party, soldered most of the boards (2008-11-16)
- Driver boards got heatsinks attached at Feb 3rd meeting during reprap session
- X, Y and Z stages assembled and put in place; X-stage motor-mount in place. (2009-02-27)
Parts Orders To Place
All the electronics have been ordered!
Parts Orders Completed
adi ordered a bunch of components for RepRap from Mouser on 2008-10-29:
