I was reading a discussion about that thermoplastic stuff in another thread here, but thought it best to start a dedicated new thread about it rather than risk sending the other thread OT, so here it is.
I've been looking into this sort of stuff for prototyping, here's one called Polymorph, and my question is has anyone used this version of the plastic, and if so, how 'hard' is hard when it sets?
For example, once it's gone completely hard, if a person were to dig their fingernail into it would it leave a mark, or is it hard enough to prevent that?
One of the descriptions suggests it's comparable to Nylon, but do they mean in strengh or hardness?
Some stuff I've seen done with it looks hard and glossy, while other stuff looks matt and Nylon-like. I'm very curious about this, cause this stuff can be coloured you know, and that means that if it sets hard enough, it would be great for pushing into a mold for making custom synth buttons, knobs, bezels, keys even!
Any hints, tips, advice, discussion about this stuff, which is hardest, what to avoid etc, is very welcome cause I notice there's actually quite a few brands/types available on eBay etc
