Where can I find a 2.0mm hardened nozzle?
Hi everyone,
I’ve been browsing the Prusa webshop and can’t seem to locate a 2.0 mm hardened nozzle for the Core One. 2.5mm would be okay too - I just a dimension smaller than 0.4, and hardened to handle abrasive filaments. Does anyone know where I might find a reliable one?
Thanks in advance for any tips or links!

Hey! I assume you mean a 0.20 mm nozzle and not a 2.0 mm nozzle? I wouldn't be surprised if there just aren't any 0.25 mm or 0.20 mm hardened nozzles being manufactured. Nozzles need to be hardened to avoid wear when printing with abrasive filaments. Abrasive filaments are abrasive because they have a bunch of particles in them (e.g. carbon fibers). A small nozzle diameter, regardless of it being hardened or not, would probably clog due to these particles. Hence, you don't see many (any?) hardened nozzles in those sizes.

Yes! Correct, 0.2mm is what I meant 🙃

And even if you made it through the printing process without clogging, you would probably not see much benefit from the small nozzle. The finer detail in the prints would be masked by the irregularities caused by the deposited particles/fibers.

If very small and detailed prints are reaaally important for you there's always the https://www.prusa3d.com/product/original-prusa-sl1s-speed-3d-printer-cw1s-bundle/ but that's a whole other ball game. And you've got to reeaaally want it for that price and cumbersomeness.

Or, you know. I could get a 0.2mm nozzle. But it seems 0.25, soft-as-cheese, is the best Prusa is offering?

Get a 0.2 mm or 0.25 mm nozzle, but forget about fiber-reinforced filaments (which won't give you clean, fine-structured prints anyway)?

If you absolutely must have a hardened .2 or .25 nozzle you can always use the Nextruder v6 Nozzle adapter and any number of E3D v6 printer nozzles. Note that if you do go this route you need to follow the standard procedure for replacing an E3D v6 nozzle. The adapter should be screwed firmly into the top of the heater block and the nozzle tightened to its final torque with the hotend heated to around 285C (there should be a small gap between the nozzle hex and the heater block when properly installed). Failure to do so may result in a leak between the nozzle and the adapter inside the heater block resulting in, best case filament oozing around the adapter and nozzle, and worst case ruining your heat block because the plastic has "welded" the parts together.

Steve

Yup, learned this one the hard way. As in encased in plastic.

Thanks all! I’ve been scouring the interwebs the last couple of evenings, and it does seem like hardened nozzles in the smaller diameters just aren’t a thing.
I get that small diameters and particles don’t mix, but I’m collecting the full range of nozzle sizes for my Core One and would prefer them all to share the same properties (heat transfer, hardness, etc.).
I saw that V6 offers plenty of options, but swapping those is a lot more hassle than the integrated Nextruder designs.
It’s all good though - I ordered the brass 0.25 mm and will just have to live with my slightly unsatisfied OCD. 😅
