1. Fine Engineering: The 3D printerintegrated nozzle is precisionengineered with a smooth inner wall featuring a roughness of Ra. 2. Extended Lifespan: The 3D printer nozzle replacement is crafted from hardened steel (SKD11) with a Mohs hardness of 7.8. This durable material ensures impressive longevity, delivering up to six times the durability of standard nozzles. 3. Enhanced Material Compatibility: The 3D printer extruder nozzle features a titanium alloy heat break to reduce thermal conductivity, paired with a hardened steel and CuCrZr nozzle. 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 Performance: With a thermal conductivity of 330 W/m·K, the copper alloy ensures even heat distribution within the nozzle. This uniform heating enhances the filament melting process, resulting in finer print quality and reducing the likelihood of printing errors or inconsistencies.
