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)?

    Durozzle is just a brand name slapped on some Chinese manufacturer. It’s probably fine, but I doubt anybody is going to come out raving about it compared to everything else on Amazon.

    IIRC, rubies are great at handling abrasive filaments, but they lack accuracy. Been a while since I looked into them, though. I use abrasive filaments so seldom that I can consider a cheap nozzle to be a disposable part of the project. Metal is generally one of the easier things to recycle.
