Thank you for replying in such useful detail!
I've been orbiting this array of technologies lately - 3d printing + silicone, and also epoxy resin - so this is all really useful info for me. Your comment about having to figure out working processes by trial and error rings true. I'll be sure to bear beeswax in mind - maybe it'll work some magic on epoxy as well.
In the spirit of reciprocal knowledge sharing, I've been using filler primer spray or smoothing prints. You're probably aware of it already, but it seems very underrated in the 3d printing community. Sands to a mirror finish amazingly quickly and easily, especially under running water. Obviously that's not a body safe surface, and I don't know what effect it would have on silicone curing, but still - one worth keeping in the toolbox.
- BillieRuben 5y agoWhich comment about trial and error sorry? I honestly rarely do the same thing twice... ADHD and all. lol Yes, filler primer is great and I recommend it often. I think I actually mention it in the article? It's just a LOT more work than pouring some wax in and out of a mould.
- dTal 5y ago>And there's so little info out there about the topic! What materials are safe/work? So many processes to master to get a good result, such expensive supplies to be dabbling with! Urgh! Not worth it, right? Ah, it seems I projected the "trial and error" part. I certainly don't often get it right first try! I would never have guessed about dish soap preventing curing, for instance. So easy for a project to end prematurely in a sticky mess...
- ncmncm 5y agoI wonder whether warming the mold up, e.g. immersed in hot water, would make it easier to get apart.
