    I have a small cnc that I cut prototype molds with, then make parts out of lead to be used formed in a vulcanized silicone mold in order to do production
    To vulcanize a mold, I need to make parts that will take 350F at 3000psi.
    Also i need the surface smooth in order to make a good production part,
    is there a 3d printer and a material that would work for this?

    Doubtful. Possibly PEEK can handle 350F but its a PITA to print and you'll need some serious mods to your printer to be able to withstand the high temps. As far as the pressure goes... I don't think there's much info out there.

    ok, thanks!
    after researching this i think my money will be better spent on a better CNC

    Nearly five years ago I spent quite a bit of time testing "3D Printing Materials" for the USAF. My conclusion was (and still is) that their "values" for Yield and Ultimate Stress and Modulas values came from somebody's dream. A "good material" tested close to 50% of the vendor's published values.
