I’m thinkin about getting one of those ruby nozzles for my printers to basically be able to print anything without ever having to worry about a degrading nozzle. I’ve seen quite a few videos about it, but I still don’t know two things:

  • Given the surrounding material is brass and only the tip being out of ruby, doesn’t the filament path where the molten filament gets pushed through still wear out over time (heavily so with CF or GF filament)?

And also

  • How good are the cheaper ones, specifically the “DUROZZLE” one (since that’s the one I could find that’s 0.6mm and cheap)?

    The idea is that just the very end of the path needs a precisely sized hole. Every other part of the path is wider, what reduces wearing, and doesn’t need as much precision, so wearing isn’t a problem.

    I have no idea how it actually works on practice. I never used one of them, and I never used an abrasive material.
