I used acetone vapor smoothing before and I don't like it, because it really softens up the details especially edges.  You end up trying to compromise by varying the time the model is exposed to the acetone, but in general, you either have a smooth but nearly detail-less model, or you have a detailed model that isn't smooth.

BTW, the model is pretty detailed.  it has some 120,000 polygons

Any reason you didn't consider vapor smoothing?

This was my first, and probably the last painted model I'll do, unless I get a much better printer, that can do really smooth surfaces (laser sintering, or UV stereolithography).  Even though this model was printed at .1mm resolution, and looks pretty good in natural plastic, really shows its flaws when painted, and really spoils the effect (zoom in on the image to see what I mean).

The problem is the flat paints bring up every little flaw, and it really makes every layer stand out.  Close up she looks like a 100 year old wrinkled lady.  Maybe next time I'll do  acetone smooth before I apply paint.  So I did what any photographer would, a little airbrushing and retouching.

The stethoscope tubes were another issue since they weren't in a flat plane, rather curving in all directions, so I ended up drawing a new stethoscope that I could print flat, then I heated it up to bend it in the original shape.

She'll get a paint job in the next couple of days.

I've had this 3DS Max file for a while now, and until now I could never get a printable STL that didn't coer a lot of detail.  Being this is a Max file, it's mostly made up of open surfaces.  The skirt, shirt, stockings, shoes, everything is layered on top of a nude model, and when Netfabb tried to fix it, it either filled in a lot of the existing detail, or it dropped most of the clothing.

So I ended up loading the model back into 3DS Max, and creating shells (extrusions) of every element that was a single open surface.  The first iteration didn't work well because the thickness of the extrusion was smaller than the minimum path of the printer (<0.40mm), so I had to thicken it up further.

This time it worked. As you can see from the photos below, she was printed sitting down, and there's a ton of support underneath and on the sides.  Removing it proved to be a major pain, but I got most of it off.  She still need clean up of the support, especially on the back of her legs and butt. 

In all I'm quite pleased on how she came out.  The skirt pleats are made of 4 distinct layers, and the shirt is actually separate from the body.  There's also a very tiny gap between the legs ad the stockings.  Once she's completely clean, I'll post additional pictures.
