Bambu Lab - P2S/H2 Series - Hotend - Tungsten carbide nozzle - 0.4 mm

While the high-flow variant is optimized for maximum speed, the focus of this standard tungsten carbide nozzle is on absolute reliability and thermal stability at regular flow rates. It is essentially the honey badger of nozzles: extremely tough, unfazed by obstacles, and ready for the toughest materials on the market. Those who regularly work with abrasive filaments and require consistent extrusion quality over hundreds of hours will find their tool here.

Extreme hardness through tungsten carbide: Tungsten carbide is one of the hardest materials available for nozzles. It is nearly immune to wear from extremely abrasive filaments such as carbon fiber reinforced polymers, metal filaments, or glow-in-the-dark materials. Where brass or stainless steel may fail after just a few grams of material, this nozzle only begins to perform.

Superior thermal conductivity: A common issue with hardened steel nozzles is their inferior thermal conductivity compared to brass. Tungsten carbide, on the other hand, conducts heat very efficiently. This means for you: more stable temperatures inside the nozzle, more uniform extrusion, and better layer adhesion, even with demanding engineering plastics.

Precision without wear: Since the inner diameter of the nozzle changes practically not at all due to material flow, the dimensional accuracy of your components remains constant over an extremely long period. This is particularly important for industrial applications where tolerances in the micrometer range must be maintained.

One-piece construction: The nozzle is made from a single piece, minimizing the risk of filament leaks at the transition points. The smooth internal path also ensures a seamless material flow and reduces the likelihood of clogs.
