Subject: Motorola Patent EDM Electrodes

I just saw this is a new magazine, "Modern Mold & Tooling", actually a
supplement to "Modern Plastics."
Motorola has a new patent, 5,818,005, for EDM electrodes:
    Using RP to create a master;
    create a flexible mold;
    fill mold with electrically conductive powder;
    isostatically press powder to form electrode.
My question. Can you RP guys make a master accurate enough for this to be
realistic? Mold makers can't handle those "barn door" units.
