That's not entirely correct (see below for context of this reply). The work you
are talking about was performed as my Ph.D. research. We didn't use any
plating techniques. What we did was to process polymer-coated zirconium
diboride powders in an SLS machine, debind the polymer and infiltrate with
copper. This created a ZrB2/Cu part (Zyrkon) that has EDM electrode
properties far superior to conventional graphite and/or copper electrodes.
That work is now on-going at the University of Rhode Island under my direction.
The note I just wrote to the rp-ml about automatic CNC tool path generation
is part of the effort to make these electrodes more accurate. (This is part of
the focus of the Rapid Manufacturing Center--RMC--that Doug VanPutte
wrote about yesterday.)

If you have any questions about EDM electrodes from RP, or the RMC, feel free
to contact me at your convenience.

It is not a dream.

Professor Walter Bradley and his colleagues in the Mechanical and Chemical
Eng. Depts. of Texas A & M University have done plating by selective laser
sintering polymer coated powders of zirconium of EDM electrodes.
