Shapeways White Strong & Flexible - Solvent?

[C855B]

We know about using Bestine (and Goo Gone) to deal with the leftover wax glaze on FUD and FXD. However, WS&F is a different process, I think - is there a recommended solvent? Or is it even necessary?

I think it's laser hardened/fused? nylon powder.  No solvent or any cleaning necessary. 

Edit: Yep, here's their material info:
To 3D print in this material, we start with a bed of Nylon powder and sinter the powder with a laser layer by layer, solidifying the powder as we go.

On a related note, in my experience paints do not adhere well to Nylon.

Not a problem. What I'm working on is a friction-fit mechanical part, not a model, so nylon's properties are ideal.

WSF  soaks up paint like a sponge. Saw one you tube video that said the year get good results by coating it in at least 3 coats of ACC. I've done both with no complaints, but only on piping and bracing.

So the paint simply wedges itself in the porous surface.  I was thinking more of a smooth monolithic nylon surface (extruded or injection-molded).

Yes. It will also absorb the first coat of ACC. The nylon powder has air pockets evidently that the paint or glue fill. You can see the color after the first coat, but also the pours in the surface. After a second coat, I CANT see them anymore, but it still does not feel smooth to the touch.
