1. Fine engineering: The 3D printer integrated nozzle is precisiondeveloped with a smooth inner wall featuring a roughness of RA. 2. Extended service life: The replacement 3D printer nozzle is crafted from hardened steel (SKD11) with a MOHS hardness of 7.8. This durable material ensures exceptional longevity, delivering up to six times the durability of standard nozzles. 3. Improved material compatibility: The 3D printer extruder nozzle incorporates a TI alloy heat break to reduce thermal conductivity, paired with a hardened steel nozzle and CUCRZR. This combination supports a wide range of filaments, including PLA, ABS, PETG, TPU, PP, PC, PLACF, PACF, and PETCF, enabling versatile applications across various printing projects. 4. Uniform heating power: With a thermal conductivity of 330 W/m·K, the copper alloy ensures even heat distribution within the nozzle. This consistent heating enhances filament melting, resulting in print quality and reducing the risk of printing errors or inconsistencies.
