When drilling any kind of plastic I crank the drill speed tn the lowest setting and gradually increase until I get effective drilling without melting.

Same here. I prefer my power drill over my dremel for that reason. With the trigger I feel I have more control over the speed. I have yet to melt a model

Well you need to be able to penetrate said model in order to make any headway. That WSF plastic is tough, but it's also prone to melting (which is why they use it).

Regular sanding becomes a exercise in futility.

Slowdown? No sweat. I can sit and drill all day doing that.

I wonder if folks would be more willing to pay for the higher priced materials, if they knew what it took to make WSF look good. We could do with a review of a few ships in different materials. Personally, I'd only go for FUD. It's a fitting acronym, considering that's the sound your shocked, unconscious self makes, when you've collapsed after seeing the price. :innocent:

I'm not questioning anybody else's mad modeling skills. But it is important to stress that WSF, or any other plastic Shapeways uses, is a different beast than the stuff we're normally used to (remember Q's admonishment to Picard about how the Federation measures itself against "pathetic" adversaries like the Klingons and Romulans? Substitute resin and styrene for the last two). So if you haven't tried working with it, feel free to contact us that have. I know that Moongrim, Tesral and I have had stuff printed and had to work with it, as opposed to others who have stuff printed for the purpose of using them as masters.

Various types of ABS. Tough stuff indeed. Lego is made from ABS.

Having customized GI Joe and Transformers toys, ABS doesn't bother me. Nylon, on the other hand, I hate that stuff.

This stuff:

You'll want to use it in a WELL Ventilated area- as it reeks.
