mold made with SiliNOT!

So I found a decent work-around for cure inhibition. SiliNOT! is a reusable silicone substitute for mold making.

It melts at temperatures above 130°F (54°C), but they suggest not going above 150°F (65.5°C), as the material breaks down at 180°F (82°C). It can also be thinned with a small amount of water for detailed parts (I add water as it begins to melt and stir in as it melts further).

While it is only good for 1-2 pulls, the material is re-meltable to re-cast as needed. I use it for recently printed SLA masters, as I am too impatient to wait for photoinitiators to "burn off" and waste way too much silicone.

That's cool, makes me want to try some casting!

Is there any specific reason to avoid silicone? I know one reason might be allergies
