RepRap is about making self-replicating machines, and making them freely available for the benefit of everyone. We are using 3D printing to do this, but if you have other technologies that can copy themselves and that can be made freely available to all, then this is the place for you too.

How did you get to these numbers? It would be interesting to actually come with such numbers for different profiles (t-slot, round) and compare.Quote

Assuming that you can achieve good tight joints, the flexural rigidity (EI) of the printed members (in PLA or ABS) should be approximately half that of an HFS5-2020 aluminium extrusion - but that is still about 5 to 6 times greater than 8 mm steel threaded rods (as used in my 1st-Generation Prusa Mendel).

I though again about small clippable triangles, and found that :
It's called the Polydron. With that kind of parts, you should be able to build any frame or shape.
If the clip is strong enough and the shape stiff enough, it should be suitable for Reprap building.
It just need a hole system at the centre to fix some hardware.

I Can't wait to get going with honeycomb infills, but wish there was a way to shift them on a layer by layer basis, rather than keeping continuous,

I think it is pointless to print the frame structure when structural materials are widely available
