I'm interested in doing some vacuforming, and there's tons of stuff on that. But there's not much in the way of the molds ro use. Can you make a mold from anything and then form the ABS on it? Or is it like 'glass/resin where you need a release agent? Does the ABS tend to stick onto the mold?
I would like to put together something using my PVC Board, then use that as a mold for an ABS version. Will the two plastics stick to each other, or would the heat of the ABS warp/bend the sintra?
I know it's a lot of questions, but I'm just curious. You know 'measure twice, cut once' train of thought.
