Why not make the whole part hollow and fill it with 2k-resin afterwards? Would also print much faster.

I thought that that was just marketing blabla until I printed my first part with the volcano and tried to break it myself.Quote
the tabs on the part printed with a standard 0.40mm nozzle could be broken by hand if you really try. However the same features printed with Volcano were impossible to break with bare hands, and we really tried! Even with pliers we struggled to delaminate the layers.

I did a 0.8 layer, speed was hard to tune, the filament is fed fast so there isn't much time to heat up to a good print temperature. As I said here [forums.reprap.org] "I might be able to push the volcano to 30mm/s, I failed at 35mm/s but it might be that replacing the Wade extruder for a full metal extruder would allow for some more pressure and thus have less issues with the lower plastic extrusion temperature."Quote

So what are the layer heights on the 1.2mm nozzle, I bet print speeds quite nippy.

I like the idea of dipping honeycombs in resin(a sweet solution), it has a certain appeal.

there are some single component epoxies but those are normally much more expensive then the 2 parts. Mixing nozzles will indeed cost around usd1Quote

That is a possibility... my sticking point with two part epoxies though is that it sets up in the nozzle after the print is done... requiring a disposable nozzle; or some sort of solvent flush system. Not an insurmountable obstacle... but definitely something to be aware of before heading in that direction. They tend to also be somewhat expensive...

Aceton vapor would be dangerous. But I like the idea about using welding. Why not ultrasonic weld the layers? No need for holes but just an extra "extruder" that welds at certain point the layers.

I don't know which is more dangerous, Acetone or ABS particulate...

Well, do you want to die in a fire now, or of cancer later?

As for recycling composites; I would suggest considering a pyrolysis process; like this:
[en.wikipedia.org]
Discover magazine had several articles about the process, the first being from 2003:

Once converted back to oil, reforming it into new plastic should be rather straightforward (I am not, however, an organic chemist, so my knowledge of the subject is somewhat limited).
