talon63 Posted December 30, 2016 Share Posted December 30, 2016 I did one where the silicone was nearly 1/2" thick and the main body of the silicone was undamaged, but the surface attached to part I want to make a mold of shredded while trying to peel it off. There are still bits of silicone embedded in the details on the surface of the part.How long was it allowed to cure? Quote Link to comment Share on other sites More sharing options...

Ive tried rtv in the past and had the same issue ...removing it was not going to happen with any chance of using it as a mold Quote Link to comment Share on other sites More sharing options...
talon63 Posted January 4, 2017 Share Posted January 4, 2017 BTW, I did pick up a little thing called the 3Doodler Start. It's one of the 3D pen devices. Simple to use, but the coolest thing I've done with it so far is use it to make molds of emblems on 1:24/1:25 kits. Shoot it on, press it down with a finger (the output isn't that hot, it uses biodegradable polyester instead of PLA) let it set for about a minute and pop it off the part. I should have some pics posted soon of the molds and the output. Quote Link to comment Share on other sites More sharing options...
