The project

What ?

A friend (Arthur S.) and I had thought to make a sort of "family tree" showing the development and variations of the reprap project (and it's inspired cousins).

Thanks to the efforts of Spiritdude we're now trying to make a useful database that could be visualized by other tools/methods, I added a google-form on top of it to allow public participation at filling it :)

How can you help?

Fill the database by using this google form !

Join the discussion on the following thread : reprap family tree (don't hesitate to mention a missing project, or if you think there is a mistake somewhere, or to improve the database, the criterias, etc.)

You are also welcome to flattr this, buy a poster, or just share it everywhere :)

RepRap Family Tree - Timeline 2006-2012 (update in progress, slowly but surely)

The latest attempt to visualize the evolution of the reprap and some others low-cost or DIY printers (estimation : 400+ projects).

RFT timeline2006-2012.png

As one can presume, since the Mendel projects are flourishing :)


You can see the growing database here.

The picture of the Prusa was made with the sketchup model found here

Old versions: v2.13x, print version, v2.9, print version, v3xL (wip) same as v2x but in a landscape format to give more room for the futur icons, v2.5 extended portrait, v2.2P

Reprap Family Tree v0.7 : You can see/edit the first diagram at (just take care of course) It was useful to start the organization.

After Darwin Should Mendel be a specific 3D printer or a technology toolbox (16-01-2009)

An interesting post by Forrest Higgs, when looking at the evolution model of the reprap.

Basically, Reprap has two models of evolution going on in parallel.
In the core team, we see what I will call a punctuated animal model of evolution while the larger reprap community is a very vibrant bacterial model.

Add ideas, and discuss ways to help make this family tree interactive and more usefull on: Interactive RepRap Family Tree

Finally I was just trying to do the same thing as they did for the , and thus it may be easier/better to make the same if I explain the logic I was trying to apply :

Life > Domain > Kingdom > Phylum > Class > Order > Family > Genus > Species

Intended or original technology (sls, fdm, etc.) > Mechanical arrangement (XZ head and Y bed, or XY head and Z bed, etc) > Size (mendel, huxley) > Material Variation (threaded rod, aluminium extrusion, etc.) > Little Variation (commercial kits like the GRRF Protoss are based on the basic Prusa mendel with just minor changes)

(not sure of the hierarchy)

But keep in mind that even if ideas are like livings things, sometimes they pop from nowhere (or have so many ancestors that it's non-representable :)

It may be nice to map other components of the machines like the RFT.
