What are RepRaps? Self-Rep
id prototyping - a machine which partially can produce parts of itself using 3D Printing technology
It extrudes a heated plastic layer by layer in X, Y and Z and so creates a solid form, called Fused Filament Fabrication (FFF) (aka Fused Deposition Modeling (FDM)) - there are other ways to build 3 dimensional solid forms parametrically, but FFF is rather simple and cost-effective approach.

I got interested in RepRap a few years ago but didn't follow up as the first models were expensive and too complex to build and use - this changed and since about December 2011 got interested more thoroughly again, thanks to several Kickstarter projects, such as Printrbot .
Due the nature of RepRap, plans are all Open Source, for everyone to adapt, alter and republish - it is like the Open Source movement, now it's about creating solid things.
Some of my thoughts on RepRap:
, Senior Lecturer in mechanical engineering at the University of Bath (UK), started the RepRap
movement around 2005 with a very comprehensive aim in mind: Wealth Without Money
His first model was the "Darwin", which was then improved to "Mendel" - at that point the community started to develop and extend the variation:
- Mendel aka "Sells Mendel", classic (1x Z-axis motor), Z-axis is X/Y-way stabilized
Not recommended to build since simpler versions exist:
- Prusa Mendel , (2x Z-axis motors), printed parts massively simplified - quasi standard now
- Printrbot , loosly based on Prusa Mendel , very simple, Z-axis in the open (one end fixated)
- Wallace , parametric version, Z-axis stabilized using a horizontal rod to connect both Z rods.
- Portabee , Z-axis in the open
- Bukobot , alike Printrbot but with aluminium extrusions (very rigid) and Z-axis is X-way stabilized
- FoldaRap , with aluminium extrusions, Z-axis is X-way stabilized, foldable
- FoldaRap , power-supply & controller nicely integrated, speciality: foldable (easy to transport)
- MakiBox , case with power-supply, controller, all in a box, speciality: pellets to filament converter built-in (still in development)
