How to cast translucent (not transparent) parts?

[justice91423]

Hi.

I’m looking to cast a few small translucent (not transparent/clear) parts that will be back lit for my Iron Giant Bolt project.

One thought is to cast them with clear resin and rough/texture the back of them, but I would prefer to cast them in a material that is inherently cloudy.

Does anyone have any suggestions?

Right now the best idea I’ve come up with is to add a small amount of white pigment to the clear resin.

Any and all experience and advice is appreciated.

You can buy resin that is translucent... I don't know if smooth on sells it (I'm sure they do) but my local brand (silpak) does.

Turns out that silpak place is close to me too. I'll check them out.

Is it for the half-sphere area?

If so (and if it doesn't have to be a solid piece for some reason) vacforming the parts in translucent HIPS might be an option.

No. Its for some small insert pieces for the lights. "lenses" for lack of a better term.
