Hello dakkas

I have for a very long time trying to figure out a way to mass produce miniature terrain.

I have tried Joint foam,(fogskum in swedish) it was very good and cheap and cool that it expanded but it has to many bubbles and holes + it is to soft.

I have tried plaster super fine in details, but it’s to heavy and drop it on the floor once, it’s over.

I can use harden plastic, witch is fluid at start, then you combine it with a another fluid chemicals and harden into plastic.
… well it is super expensive so no….


Do you dakkas have any suggestion or ideas how I can solve this problem? I’m going mad here :(

Is that the mould?

You need some sort of release agent so it doesn’t stick

If that fails you may need to look into 2 part resin

2 part resin and release agent is all you need.

I don't consider it "that" expensive. It usually works out to about 2 or fewer US Cents per figure. Terrain can eat a lot so the solution is inserts for the mold that reduce volume and result in a hollow casting.

As for plaster there are advanced plaster type materials that include resins and or fiber filling for strength. You can do that with your plaster by adding shredded newspaper in small amounts or fiber-glass fibers

You can also use talcum powder (which you can also get unscented, so your terrain doesn't smell like babies or grandmothers) as filler for polyurethane resins.

I've used up to 30% with no issues. It turns some translucent resins opaque and more white from yellowish, but it works. Has negligible effect on hardness or durability when cured, but makes it slightly easier to trim while still soft.
