I don’t print any abrasive materials at all. Pretty much only normal PLA and PETG.
I noticed, that my print quality gradually went down quite a bit, especially in the last few prints. I had a lot of stringing, weird blobs, and scarred surfaces.
Now, the print quality is as good as it should be!
They are dirt cheap. You can get a set of 10-15 generic ones, in different sizes, for only a few bucks. Don’t forget that they are consumables.
I’ve been using a oxbidian nozzle and printing wood and GID occasionally. Seems to be holding up very well. It’s a more expensive option but might last as long as 3 or 4 normal nozzles and I think it’s also notable that you’re not dealing with as much of a downslope in performance on your way toward a new nozzle each time as you are with traditional brass.
