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.
Forget about tungsten, get yourself a Diamondback nozzle They’re pretty much indestructible regardless of the hardness of the filament! Ask our boy Zack over at Voidstar Labs
Bought one of these a while back, and it’s been great. Yeah, you can get hundreds of cheapo nozzles for the price, but not having to deal with increasingly shitty prints and nozzle changes has made it worthwhile for me, at least. I don’t even use abrasives, mainly just matte PLA.
Ackschually
PLA is not abrasive by itself but it’s additives might be. Titanium dioxide is a common colorant for example which might end up eroding your nozzle slowly.
This is what I did. I have not had to change nozzles since.
I will say, however, that this will definitely prompt you to git gud at cleaning nozzles, and inventing jigs and tools for doing so, because you’ll no longer just want to shrug and throw away your current nozzle if it clogs badly.
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
