    We have for some years used cad-cam milled wax masters for our work
    in cast silver, gold and platinum. We have the master milled then do
    a fair bit of hand work on the wax before casting - these are usually
    one offs or two offs (cufflinks) After seeing some impressive results
    at a trade fair of what a wax printing rapid protype machine could do
    we decided to give it a try as the waxes seemed much finer (no tool
    lines) and very accurate. Unfortunately they did not cast well at
    all. The wax used in these machines must be of a different
    composition and was breaking down during casting (we lost one wax
    altogether) so we ended up with castings that needed far more work
    than if we had done them the original way. I just wondered if anyone
    else had had similar experiences?
