    which filament for printing a positive mold?

    Good day everybody

    my target is to laminate a glassfiber sandwich model airplane wing. To achieve that, I want to 3d-print a positive mold and then laminate the negative mold.

    Which filament is recommended? It should be:
    sturdy
    little or no warping
    able to sand
    epoxy resin should stick to it/or filler for a smooth surface

    thanks for your help,
    Chris
