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.

I was really worried about this because I hear it constantly. I did some tests using elegoo standard grey 8k resin and there was no cure inhibition at all with Dragonskin 30 silicone.

This isnt true for all resins but im glad I can skip a step because the tin cure I tried did not work well for dice molds.

Siraya tech has a line of resins that have similar properties. I have simply had limited luck with this (could be my cleaning/curing process, idk).

I found this stuff for a fool-proof solution.

I clean in 99% IPA for 10 minutes and then cure for 10. Overkill on both but that may help drive off the compounds that cause inhibition.
