"Re-Purposed Plastic Blister Mould Concept For 15mm SF?" Topic

I know that other gamers have done the same thing with plastic blister packaging from other home and electronic goods, but check out what TMP's "Goober" did here:

QUESTIONS:

A) If the blister packaging is thick enough, aside from using plaster and resin, are there other materials that could be poured into such recycled plastic, without damaging them too much to be re-used as moulds several times?

B) Got any other tips related to casting into such improvised moulds?

Thanks,

I would think so. You'd need to use a release agent of some kind to make sure it didn't stick, but I don't see why not. You might be able to use talcum powder if you didn't want WD-40 or cooking spray on your models.

Sort-of-on-topic: When I was in the Army, during the budget crunch in the mid-90's, we couldn't get any inert training landmines, and even if we did, we weren't supposed to blow them up. So we got a bunch of plain round plastic cake trays and lids from a local grocery store. We sprayed the insides with WD-40 and poured them full of Quikrete to make landmine proxies we could destroy with live demo. The following year, the Army actually sent us some heavy-duty vinyl molds of landmines to use for that same purpose.

I pretty much trashed the moulds each time I created one of those hab domes. Fortunately I had a section of the blister packs to work from. I've since cast with a florescent light bulb package and Mr. Kipling cake bar trays, both of which came out very well.

Very cool.

Any other possible casting medium that could be used with plastic blisters, besides plaster?

Those look really great, and very Sci-Fi-ish.

Fill it with plaster, and leave it in for strength.

Then, make a silicone, or latex mold of it.

You can cast resin in the former, and harder plaster, like that dental stuff, and/or fake cement plaster.

One could always use the blister as a mold.

But I find that that defeats the great advantage of extreme light weight of the blister. I have used blisters for years with very good results. See:

If the blister is too weak, try reenforcing it with lines of cheap epoxy glue to act as a support structure. Do this on the underside to avoid any unsightly effects. If even more support is needed try gluing in old sections of sprue or similar.

Yep just got the light bulb ones today.

Put in the to be used box, not sure if I will cast or just trim and paint them.

I have found is adding a DROP of the little bottle for clean dishes for the dishwasher.

Seems to help bubbles as well.
