The high wear resistance of our tungsten carbide nozzles will ensure that even the most abrasive filament can be printed with confidence.
The high thermal conductivity of tungsten carbide means you can print faster.
Tungsten carbide will not soften at high temperatures like hardened steel, resulting in a longer lasting nozzle. Print up to 500c with high abrasion resistance!
Our tungsten carbide nozzle is a single piece, single material nozzle, meaning thermal conductivity and optimized flow is maintained through the entire nozzle, unlike multi material tungsten carbide tipped nozzles.
Tungsten carbide nozzles are less expensive to manufacture than ruby or sapphire tipped nozzles and maintain better flow and temperature stability at the nozzle tip.
Most importantly, our tungsten carbide nozzle is available NOW! No preorders.

DONT EVEN BOTHER USING WITH THE STOCK HEAT BLOCK ON PRUSA MK3S+.
As others have pointed out here as well as many other sites including reddit, you must use a plated copper heatblock with this nozzle or it WILL loosen off after a day of printing even when torqued properly. Spool3d should include this information or similar in the description even if "mines working just fine" or what have you. If the failure rate is this high there is a functional problem of thermal expansion of metals between the stock aluminum V6 block on the mk3s.
That being said. It seems to be working now and that's cool (got a plated copper heat block on the stock heatbreak).

Not recommended with aluminum heater block
3/5
While the idea of this nozzle is fantastic, and the nozzle itself seems great, it just will not stay tight on my stock aluminum E3D heater block on a stock Prusa i3. It'll be great for maybe 5-10 prints but then it will have loosened itself enough that filament starts leaking up the top of the heating block and burnt filament dribbles down in blobs randomly into your print, making things a mess. (It also doesn't help that, having loosened itself, it will have messed up your carefully calibrated base Z layer offset).
I can go back and re-tighten it to 3Nm (and recalibrate the base layer), and it'll work for a while again, but after a few days the dreaded blobs of burnt gunk start showing up to ruin my prints again.
There are lots of reports of this happening with tungsten carbide nozzles, unfortunately (in general: not just this one): the leading hypothesis seems to be that the thermal expansion properties of tungsten carbide and aluminum are too dissimilar for it to stay tight. People with copper blocks (like the E3D plated copper block, also sold here) seem to have much less trouble.
So if you have a stock E3D heat block (which is what a Prusa i3 comes with) either stay away from this nozzle, or also upgrade your heater block at the same time.

Great nozzles
5/5
I use tungsten carbide nozzles on all my Prusa printers and haven't had any problems with the Spool3D brand. Unlike other brands, it's solid tungsten carbide, not an alloy, and not just the tip. And unlike hardened steel I never had to change any of my print profiles, the thermal properties are very close to brass or coated copper. Spool3D seems to be the only manufacturer covering a broad spectrum of TC nozzle sizes. The nozzles are not cheap, especially if you factor in shipping to the U.S., but (I hope) they'll last forever.

Tungsten carbide M6 Nozzle
1/5
The thermal specs of this nozzle were worse than hardened steel. It is supposed to be similar to brass. Carbon fibre prints failed so I ran some tests with PLA. Brass nozzle 210C had great layer adhesion and printing. Hardened steel nozzle 215C had good prints. Tungsten carbide nozzle: 210C extruder grinds filament after a couple layers, 215C no layer adhesion, 220C layers adhering but still weaker than normal, 225C good print. Put the brass nozzle back on and 210C had perfect prints again. This TC nozzle did not live up to its specifications.

Tungsten Carbide nozzle 0.6 mm
4/5
Solid product, prints at temps same as brass nozzles. Inside is not as polished but that’s because carbide is though to work with.
For such price it should have come in nice metal box in foam like Phaetus recently introduced carbide nozzles (they only have a carbide tip like Dyzedesign), not in a plastic bag.
Shipping to europe is crazy expensive, coming in bubble envelope.
Guys, you should really work more on presentation of a product and do something with shipping as it definitely doesn’t cost that much via regular post.

Works great
5/5
I've only had it for a week (after being held up by Fedex at the Canadian/US Border for two weeks...). But so far it's performing great. Excellent prints with my Prusa Mk3S+ using standard profiles, no need for adjustments.

Spectacular
5/5
I've got around 50-100 hours of use with abrasive filaments on this nozzle and it has performed wonderfully, and consistently. Brass nozzles would require swapping every 20-40 hours or so on the same filament. Having used both this and the Dyze design tungsten carbide nozzle, this one is superior, because it is made of tungsten carbide all the way through, whereas the Dyze design version has a steel housing with just a tungsten carbide tip. This means the Spool3D tungsten carbide nozzle has better thermal conductivity performance which rivals brass and wont require you to change print temps to compensate for a steel or steel-core nozzle.
Of course the shipping price stinks, hopefully they can do something about that! Excellent product.

Not worth the price
1/5
20$ shipping and VAT appearently was not included so had to pay an additional 20$ to receive it (TOTAL SCAM, 40$ for a 3g package, costs 3$ with a simple tracked letter). I make thousands of orders and taxes are always covered by the seller
Do not buy if you don't want to get ripped off, just get the olson ruby from prusa website.

Tungsten Carbide RepRap M6 Nozzle
5/5
Prusa I3 Mk3S, swapped with stock nozzle, Same Z calibration setting. Did not need to change anything. Printing 3DXTech CarbonX Carbon Fiber PETG Filament without any problems. Using PrusaSlicer Prusament PETG settings.

Great All-Purpose Nozzle
5/5
I bought this nozzle to use with abrasive filaments, and plan to use it full time in my Prusa i3 MK3s. The product appeared well made, decent surface finish for tungsten carbide. All profiles used with my 0.4mm brass nozzle work great with this, and the print quality is equal if not better. Shipping to the US was fast and easy. I would not hesitate to shop with Spool3D again.

Keep loosening
4/5
The idea is great and the M6 nozzle perform like a champ. The only problem is it loosen after a couple of prints. No matter how hard I tighten this thing at a temperature of 280C. I bought cheap brass nozzle and now everything is working perfectly. The thread on my tungsten nozzle is .005" smaller than other nozzles. By the way it is not even in the tolerance range of a M6 x 1 thread major diameter.
I also bought the MK8 version and this one was even more terrible, There was a problem of under extruding. I also went back to a brass nozzle, and everything is working back to normal.
UPDATE: After reaching out the spool3D customer support, they asked me to send back the faulty item and sent me a new one. I have been using the new nozzle since. I am printing glow in the dark and carbon fiber PETG without worrying about the wear. It is printing flawlessly. Thank you very much for the replacement and the fast response.

Last nozzle you'll ever need
5/5
Really happy with this. After a lot of printing I can say it prints very well. No need to retune profiles, it works just as well as brass. Handles carbon fiber infused filament. Machining on the inside of the nozzle looked really good, couple really tiny burrs but nothing that would be a problem.
I had to re-tighten mine 3 times before it stopped leaking, might just need more torque versus a brass nozzle. Has been working well since then.

Exactly what I was looking for!
5/5
Finally! A robust* nozzle that I can seamlessly use to switch between abrasive and non abrasive filament, without having to worry about which print profile I am using. I love that all my brass profiles work perfectly without changing anything and I still get the same layer adhesion as I would with using the brass nozzle. This was not the case with using a couple of the other more popular hardened steel nozzles. So far I couldn't be more happy with the results.
*I only have put a few CF-PETG parts through it so far but given its material should be very robust.

Nozzle of my dreams, slightly loose but not a problem.
5/5
This is the nozzle of my dreams, good thermal conductivity (good as brass), extreme hardness (as hard as ruby), features one-piece-construction, all with a fair price tag. It looks really good too, the photos do not do this nozzle justice.
The only (non)-issue is that the threads are a very slightly looser fit. However, that does not impact performance in any way.
This is the only nozzle you will ever need.

Tungsten Carbide Nozzle
5/5
I recommend this tungsten carbide highly. It mechanically matches an E3D brass nozzle close enough that only Live-Z needs to be adjusted. No PINDA repositioning necessary as opposed to a nozzle that is too long or short. Its filament inlet has a small chamfer similar to a E3D brass nozzle. One piece construction means I don't worry about it coming apart or having any portion of it composed of lower conductance steel.
Thermal conductivity is excellent. On the print-fan finicky Mosquito hotend, a hardened vanadium steel nozzle would require a 20 to 30C boost in nozzle temperature to achieve almost brass equivalent filament melt. The Spool3D tungsten carbide nozzle solves that issue completely. I can use my normal brass nozzle print profiles once more.
This nozzle provides both abrasion resistance AND good thermal conductance making it both durable AND capable of printing well. I will not go back to a low conductance, hardened steel nozzle after using tungsten carbide.

Early days yet, but nozzle installed easily on my Prusa Mk3S. I’ve printed a few models with carbon fibre reinforced nylon with excellent results. Bodes well for the future.
Fast delivery from Spool 3D from Canada to Australia.

Best Nozzle Available
5/5
I personally believe this is the best nozzle available anywhere. The flow is super consistent, it heats like a brass nozzle and it will literally last forever. It is the last nozzle you will ever have to buy. Buy this and an E3D pro silicone sock and you'll be set until you need another one for your next printer.

High heat

Works great, Had to turn down temps (normally have hardened steel).
I hope to see a .25 nozzle in Tungsten Carbide too.
