Using WSF for Resin casting?

    Greetings,
    Just getting started on a project and would like to know if WSF is suitable for making molds for resin casting. Has anyone had experience with that? The description under the material claims "SLS is not suitable for molding." What do they mean by that??

    Thanks in advance for your replies.

    The SLS material is very porous. This means that if you make a mould from it, removing the master from the freshly cast pattern will be difficult and the mould will deteriorate quickly from casting because the surface is so rough.
    You could make it suitable by sealing and sanding the model prior to making the mould though. But that's a lot of work, so maybe using one of the detail materials would be a better idea.

    Which material would be better, the White or the Dark detail, or would the Grey Robust be better still?

    I don't think white or dark detail are all that different, both are quite suitable for resin casting I believe.
    Grey Robust might work, but the level of detail and smoothness it can achieve is limited. The printing scan lines are very visible in grey robust.
