hey guys, I've just bought a roll of Nylon.
Is a hardened steel nozzle required? Will a brass nozzle wear?

For generic nylons, the nozzle will not wear. if it's not a metal hotend, you may melt PEEK. If it's a filled nylon, it may cause wear, but I haven't seen any filled nylons yet.

cope413 might know more about the blue nylon trimmer line. It might have glass fibers which could wear a brass nozzle. Taulman's is pure nylon and shouldn't cause an issue at all.

The blue trimmer line I use (Desert Extrusion) - is virgin nylon 6. No fillers.

At one point, I believe Taulman used desert extrusion (in arizona) for some production.

Either way, no wear on a brass nozzle from it.

The metal-fill filaments (bronzefill, brass fill, copperfill, SS PLA, Fe PLA, tungsten ABS, bismuth ABS, etc), and the carbon fiber filaments will wear through brass nozzles. The CF will absolutely annihilate them. I've also seen reports of some glow-in-the-dark filaments having abrasion issues with brass.

If you do switch to an SS nozzle, keep in mind your extrusion temperatures may need to get adjusted. SS has a much lower K value than brass (about 1/10th the thermal conductivity), so you may need to bump up temps if you notice extrusion issues.

Also, FWIW, "pure nylon" isn't a super useful term. It's "pure" in that it has no fiber fillers or other potentially abrasive additives, but "Nylon" is a large group of polymers. Some are homopolymers - that is, a polymer that consists of a single type of monomer. Others are copolymers - which are polymers that are made of up of more than 1 type of monomer.

Thank for your inputs guys, that gives me peace of mind, I don't like swapping nozzles.
But I will not be getting the filament any time soon. Since today, the only supplier of black nylon is closed for holidays :(

I am new to nylon 3D printing and have learned a lot from the last few weeks. I am trying to get a 3D printer for my small business and I have received few recommendations about the Prusa 3D printers and looking for some solid reviews? Is there any good printer that you can recommend? I read some of the 3D printing-related articles at https://printerdeets.com and feel like there are many factors that I need to consider before buying my 3D printer.

Please share your experiences!
Cheers
