= RepRap Old from 2008 = [[User:Romyilano|Romy]] - ''this is REALLY OLD. Like from 2008 old. Where were you in 2008? Is that when your okcupid date was born? We have to update this.'' From reprap.org: [[Image:Reprap.jpg|thumb|right|Reprap image 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 β¬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 β¬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. == Links == *http://en.wikipedia.org/wiki/RepRap_Project *http://reprap.org/ *http://www.reprap.org/bin/view/Main/McWire_Cartesian_Bot_1_2 - easy to follow instructions for a kit version of reprap. *http://objects.reprap.org/wiki/Builders - the RepRap Builders wiki *http://store.rrrf.org/ - the RepRap Research Foundation store == Participants == * [[User:Orph|Orph]] * [[User:Adi|adi]] * [[User:Ioerror|Jacob]] * [[User:turkshead|TurksHead]] * [[User:nejucomo|nejucomo]] * [[User:arcanology|Al]] * [[User:Mlp|Meredith]] * [[User:obscurite|Obscurite]] * [[User:mrericboyd|Eric Boyd]] * [[User:Martinbogo|Martin B] == Plan == * decide what system to build ** what print materials?

In particular, the [http://reprap.org/bin/view/Main/ExtruderMechanicalParts Extruder] "print head" is pretty much independent of the chassis mechanism, and looks like a fun project.
