    Dear forum,

    Can you tell me if any of the Shapeways materials are suitable to be used as a master model for vacuum casting?

    The model to be cast is a shoe sole.

    The finish needs to be really smooth so that rules out white strong flexible.

    Cheers

    :)

    I did see a demo of a thermoform vacuumed shell over a piece in a material much like the detail material. Is that the kind of vacuum casting you're looking for?

    No, not really. It's more like suspend the master model in an acrylic box with metal pins coming out to act as vents. Then puour in liquid silicon. Wait until hardens, then de-mould to make female cavity. Then pour in rubber, polycarbonate etc
