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.

Wow, I never thought about that. Are "brute force" coolant pump would destroy the wood. I'll have to see if I can get my hands on some sintra.
