    The output material for perfactory machines such as EnvisionTec is a
    very tough laser-cured superpolymer that does not burn well. The
    thermal expansion of the model as the oven ramps really weakens the
    investment and special burnout procedures, and sometimes materials,
    are necessary. It is for this reason that we switched to the new
    "hybrid" material for our customers' RPs- part wax, part polymer.
    The wax melts out at lower temperatures, leaving a matrix of polymer
    that does not expand strongly enough to damage the investment. I
    would gladly grow something in this material for you if you'd like
    to try it. Otherwise, for RPs you want to go straight to cast I'd
    recommend a Solidscape grown model. 

    On a related note, if you ever have trouble manufacturing a CAD
    created piece, I would gladly take a look at your file for you to
    help overcome any casting trouble.
