David,

    If you can't cast it I suspect that the design is going to be even
    more of a problem production casting from a mold. 

    Maybe the designer will have to re-think his model. Model making is
    more complex than just what appears on the screen. Every
    manufacturing step (limitation) has to be taken into account, good
    model making is technically more complex than even really fancy
    custom work. 

    No real evidence but I suspect that your friend is using a straight
    end mill, a tapered bit (15 included with a .2mm tip) will yield
    almost the same visual results but be much stronger. And hopefully
    the back is hollow, thick castings are always much more difficult.
    Thick and fine details just don't mix well.
