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.
Not sure if I see a difference but it’s more expensive.
The link I sent does have material property comparisons with most other nozzle materials, including tungsten carbide.
But, given that they’re trying to sell the Diamond nozzles in the first place I would take all those values with a grain of salt.
From their information it’s like super amazing but that’s not always translated to actual use. I tried finding more reviews but couldn’t find anything.
Do you have one of those? Have you used any other hardened nozzles? I’m still under the impression that the ruby tip is king for the cost and reputation
