• WEAR RESISTANCE FOR ABRASIVES:​ Stop replacing worn-out brass nozzles! Forged from premium SKD11 hardened steel, this P2S nozzle is practically indestructible. It easily handles highly abrasive filaments like Carbon Fiber (PA-CF/PETG-CF), Glass Fiber, Wood, and Glow-in-the-dark without degrading the tip, ensuring perfect dimensional accuracy print after print.
• UPGRADE Quench-Polish-Quench NON-STICK TREATMENT:​ Say goodbye to clogs and messy hotends. Our exclusive Quench-Polish-Quench surface treatment is enhanced with a DLC nano-coating, creating an ultra-slick, low-friction shield. It acts like a "non-stick pan" for melted plastic, drastically reducing filament adhesion, preventing blobs, and delivering a clean, hassle-free printing experience—even with stringy PETG.
• HIGH-TEMP PERFORMANCE: Push your 3D printer to its absolute limits. Engineered to withstand extreme heat up to 450°C (842°F), this hotend upgrade unlocks the ability to print industrial-grade engineering polymers including Nylon (PA), PC, PEEK, and PEI. It is also fully backwards compatible with your everyday PLA, ABS, and TPU.
• PRECISION MACHINED FOR SMOOTH FLOW: Flawless layer lines start here. CNC machined with a perfectly centered, burr-free orifice and an ultra-smooth inner wall (Ra<0.4) enhanced by the Quench-Polish-Quench process. This drastically lowers extrusion resistance, providing a consistent, buttery-smooth filament flow for stunning, high-resolution print quality. Before use: Tighten nozzle clockwise with wrench until snug, then install. Do not over-tighten to avoid thread damage.
• DROP-IN UPGRADE & PRO-TIP:​ Perfectly compatible with [Bambu Lab P2S, X2D, H2S, H2D, H2C, A1, and A1 Mini] hotends. Available in versatile sizes—0.2mm, 0.4mm, 0.6mm, and 0.8mm—and a range of stylish colors including Purple, Blue, Black, and Silver to match your setup.
• PARAMETER ADJUSTMENT & CALIBRATION:​ The Quench-Polish-Quench (QPQ) hardened steel nozzle offers exceptional wear resistance. Its thermal conductivity is lower than that of standard brass or copper nozzles. To compensate for the heat transfer impact, the printing temperature needs to be increased by 5°C to 15°C compared to standard nozzles (e.g., if PLA prints best at 200°C, adjust it to 205°C–215°C). Before printing, always re-tighten the bottom black nozzle. Since replacing the nozzle alters the thermodynamics of the hotend, please send the PID calibration command (usually M303 E0 S210 C5) via the printer screen or console to recalibrate and save the data.
