    Why not go straight to carbon for the first one? Cloth for a project like this would only be $50-60 tops.

    What is your plan for laminating? I have tried wet laminating stocks in the past with no vacuum and it is very tricky to get good consolidation around the tight corners. If I were to try it again, I would certainly use vacuum.

    Ill be watching your project with interest.
    Hey @SixtyTen

    Thanks for the interest.

    Although I agree that you could do this with inletting a foam/resin core, the joy of a 3D print is that it is accurate, stable and very light weight.

    Fiberglass I’m interested in using as it’s easier to layup and I can add layers in areas that need it and leave it thin where it’s not required. A multiple layer 2oz and 1oz laminate using epoxy will be super strong. Easily strong enough for my needs.

    It’s fast to get the foam shaped and the 3d core is inexpensive so I plan to try a couple of different ways of making it.

    I hope this gives others ideas to try the same

    If any Auckland members want PET foam core I have quite a bit left as you have to buy a full sheet at a minimum.
    veitnamcam, SixtyTen and dannyb like this.
