I've experimented with 3D models for a bit (designed by somebody else) 
and I'm not entirely convinced about the whole process. Obviously, my 
interest is modelling. I ordered from Shapeways.

First, I ordered a couple of caboose cars (or at least, the Dutch 
version thereof). The material was very rough, so I set about filing it 
and sanding it. The warmth of my hands made the material deform, and it 
remained deformed. (After ordering resin versions of the same thing, and 
abandoning that project too, they're now on order from a normal 
manufacturer.)

The second was a model of a Mack Titan (Australian version) to build a 
model of a road train. The material was a bit better this time around, 
but there's very clear stepping on surfaces that are not at a straight 
angle, or that are curved.

I suspect that the materials used by Shapeways have something to do with 
it, but often they're the only ones who can provide you with a certain 
model, unless you go and design it yourself - which is not very likely 
to happen any time soon.

3D carving, now that's another interesting approach, although I doubt it 
will solve the resolution issue unless you throw a lot of money at it.
