OK I have a 3D printer which is fine for slowly printing one expensive plastic figurine
and yes aware of EULA restrictions on DAZ figures/models I do have others like Makehuman etc
before you ask
anyway was thinking of 3D printing my master objects then doing plaster casted replicas or candles, chockies, soaps etc to paint and give to unwilling friends and rellies as cheap gifts etc.
Was wondering what the best mould (mold to americans as I found searching) making method was.
And not the green stuff that grows on my forgotten fridge contents.
I see there are latex compounds you can paint on like a glove, pressing into casting sands, silicone moulds,
flour, oil and salt cooked dough is one method I used as a kid to press stuff in and make an impression to fill for plaques l but one sided.
Likewise my old friends the chocolate moulds.
Was hopping some experienced casters may be amongst you to offer tips and suggestions.

    I actually like the painted latex for molding. You just need to have patience and do multiple layers to build up the thickness. Not for detail but to make the mold itself more sturdy for multiple uses. I tend to use 4. Let it dry completely depending on how humid of an area you live in and you should be good to go. I make a mold holder out of either sand or ice.

    I thought the Latex painting looked the niftiest but was pretty new looking to me, glad to hear it is that easy, I may go for it too.
    kitty litter too would make a good mould holder I imagine.
    Can it take hot wax though for candles?

    I've done plaster, resin (NOT a good idea ruins the mold), wax, clay, and soaps. So long as you have a good thick build up and arent using really scorching temps you shouldn't see any mold degradation.

    Great idea Wendy. I think since we are dealing with detailed 3d figures, "scale" is your friend. I would suggest to print the master as large as you can and go with a one-time use sand mold and make aluminum or bismuth casting to make more durable castings.
    Bisthuth is very low temp and creates really neat pweter type products that can easily be painted with acrylic. Aluminum cans be done on the cheap using beer cans.... Of course there a rare commodity down under, but you might scrounge up a few if you look hard enough. Some really cool "how to" vids here from LifeBuzN (se this and the following) : https://youtu.be/PQ4mLdyp-Zw
