- Precision-engineered integrated nozzle: The 3D printer integrated nozzle is manufactured to tight tolerances with a smooth inner wall (surface roughness specified as RA). The precise internal profile promotes steady filament flow and consistent extrusion. - Long-lasting hardened-steel tip: The replaceable nozzle tip is made from SKD11 hardened steel with a MOHS hardness of 7.8. This high-hardness steel resists wear from abrasive filaments and delivers up to six times the service life of standard nozzles, reducing downtime and replacement frequency. - Optimized thermal assembly for broad filament support: The nozzle assembly combines a TI alloy heat width (to reduce thermal conductivity), a hardened steel nozzle, and CUCRZR (copper-chromium-zirconium) alloy. This material pairing improves thermal control and mechanical durability, enabling reliable printing with a wide range of filaments: PLA, ABS, PETG, TPU, PP, PC, PLA-CF, PA-CF and PET-CF. - Even heat distribution for better melt quality: The copper alloy in the assembly has a thermal conductivity of 330 W/m·K, enabling uniform heat transfer through the nozzle. More even heating improves filament melting and flow, producing finer surface finish and lowering the risk of under-extrusion, blobs, or other print inconsistencies. Key benefits — why you need it - Fewer nozzle changes: Hardened SKD11 tip and high wear resistance extend service intervals, saving time and lowering running costs. - Reliable multi-material performance: Designed to handle both flexible and abrasive filaments, from TPU to carbon-fiber blends, without rapid wear or frequent clogging. - Improved print quality: Precise internal geometry and consistent thermal behavior produce steadier extrusion and smoother prints. - Stable thermal control: TI alloy heat width and high-conductivity copper alloy work together to maintain a stable thermal zone at the melt point. Technical highlights - Nozzle type: Integrated/extruder nozzle (replacement for standard 3D printer nozzle) - Nozzle tip material: Hardened steel (SKD11), MOHS hardness 7.8 - Thermal components: TI alloy heat width + CUCRZR (copper-chromium-zirconium) alloy - Copper alloy thermal conductivity: 330 W/m·K - Inner wall finish: Smooth, specified as roughness RA - Durability: Up to 6× life compared with standard nozzles Typical applications / use scenarios 1) Printing with abrasive fiber composites: When printing PLA-CF, PA-CF or PET-CF parts, the SKD11 hardened-steel tip resists abrasive wear and maintains dimensional accuracy through long print runs. 2) Mixed-material prototyping: For projects that cycle between PLA, PETG and TPU, the assembly’s thermal control and smooth internal profile reduce stringing and improve surface finish across materials. 3) Production runs requiring consistency: For small-batch production or multi-hour prints in ABS or PC, even heat distribution lowers extrusion variability and reduces failed prints. Practical notes - Replacement compatibility: Designed as a replacement integrated nozzle for compatible extruders; follow your printer’s instructions for installation and torque. - Material handling: The nozzle’s hardness and thermal design improve longevity with abrasive and high-temperature filaments, but follow manufacturer temperature guidelines for each filament. - Maintenance: Periodic cleaning and correct retraction settings will further reduce clogs and maximize nozzle life. This nozzle assembly balances wear resistance, thermal stability and material compatibility to deliver longer service life and more consistent print results across a wide range of filaments.
