[…] one of my previous blog posts, I linked to Joshua’s blog post about preventing cure-inhibition. His solution was to use InhibitX. In the process of finding a working recipe, I also got a bottle […]

[…] There are special solutions for painting the mold to prevent inhibition. However, they seem not to work as flawlessly as the manufacturer claims. If you are interested, read Joshua’s crusade on his blog. […]

I used inhibitor x and my silicone stuck to the sla print parts

In reply to Cornellius. I imagine this will vary with the resin formulation. I'm surprised yours cracked that fast!

In reply to david. Yes, very likely! I just couldn't in my case because it would have messed up the tolerances. It had to be the exact part off the printer, and perfectly repeatable.

Thanks for this info. I’m wondering if washing, curing and then coating with acrylic enamel will fix the part for casting. I’ve used Rustoleum 2x Acrylic Enamel spray on polyurethane foam (Renshape) with good results. I’d try myself but I;m trying to figure all of this out before purchasing the resin printer. I do have a resin SLA print from years ago. Not sure if the resin is similar at all…

In reply to Cornellius. Thanks for sharing that! It could be a difference in the resin formulas we're using.

2. Heat your part at 300F/150C for 2-3 minutes

For me, 150C in the oven caused instant cracks in the printed object (maybe it was too early right after it was printed?)
I prefer 70-80-90C steps for about 20 minutes each and no cracks

Do you find that you can re-use the residual jar of inhibit X liquid? How many uses do you get out of each batch? I want to try this method, it just seems cost prohibitive as the cheapest I can find inhibit X for is between $60-$70. Very helpful post, hopefully I’ll have a successful silicone mold soon!
