Yes. Because our router has a Unist mister on it, the coolant it sprays could absorb into wood. Depending on the wood you use, it could maybe even cause it to swell? I'm not 100% sure as I've never let coolant sit around on wood to see if this happens, but I would be concerned.

Over other plastics - yes - it turns out Sintra can be had for quite cheap, and we've started using it for some of our in-class projects and prototypes. Its surface properties are grippy enough to provide a nice clamping surface.

Now we don't see the Sintra as a "sacrificial material" as we barely scratch the surface of it when we cut parts. As I mentioned before, these strips last us about a year before they get scratched up badly enough to be replaced.

If you were considering using it for a true sacrificial material, where you're trashing the Sintra sheet every time you cut parts, then it's probably not going to be very cost-effective.
