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.

Tungsten Carbide Nozzle

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.

Tungsten Carbide Nozzle

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

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.
