Hi Yakov,

I noticed at the 6th European RP Conference a couple of weeks ago that
the Charlyrobot's Stratoconception Machine uses milling (subtractive) -
stacking (additive) approach to fabricate parts. Maybe this is the kind
of Hybrid Machines you are talking about?

        Yes, that's exactly what I meant. I apologise for not phrasing
the question
        more precisely. As several people pointed out, LOM, Cubital,
Sanders etc are
        all hybrid machines, but my question was not referring to those
systems, but
        to a combined RP/CNC machine.
