    This is way too much work for a simple lead mold. I guess if you have to buy the kildry oven. Why not just buy the laed weight and be done with it. Too much cost here and time for a dive weight.

    The title is not correct, it's not an aluminum 3D printed mold, its a mold created from a 3D printed part to make and aluminum part. You totally mislead people with the title and you don't show the part where you remove the 3D printed master part either.

    When I've done lost PLA casting before using dry playsand my sand always soaks up a really sickly toxic kind of smell, does this happen when using greensand?

    this is retarded, do you want to get lead poisoning.

  7. Ask me says

    Ooppss.. you forgot to show one of the most delicate steps in the process, how to remove the mold. Most important is the release agent, in this case baby powder. There are different techniques to remove the mold, first a high frequency vibrating device is used to free the mold before or after spliting the box, then screws are used as handles to pull out the mold.

    How did you take the plastic mold out of sand

  11. Mad Man Mitch says

    Can you re-use the sand or do you throw it away?

    If you want to sell one of these moulds I'm very interested.
    I live in Sweden, so I assume shipping wouldn't be that bad!

    Stilig serie, selv om de kommer i feil rekkefølge:) Må prøve å støpe alu en gang jeg også. Ser spennende ut.
