Feature: 1. Integrated All Metal Design: The nozzle and heat break feature a full metal integrated design that facilitates quick disassembly and replacement. This simplifies maintenance and enhances user convenience, making it compatible with popular 3D printers such as the for K2 Plus and for HI models. 2. Upgraded Material Compatibility: The 3D printer extruder nozzle is constructed with a Ti alloy heat break to reduce thermal conductivity, paired with a nozzle made from hardened steel and CuCrZr. This combination supports a wide range of filaments, including PLA, ABS, PETG, TPU, PP, PC, PLA-CF, PA-CF, and PET-CF, allowing for versatile applications in various printing projects. 3. Extended Life: The 3D printer nozzle replacement is crafted from hardened steel (SKD11), boasting a Mohs hardness of 7.8. This robust material provides an impressive life, delivering up to six times the longevity compared to standard nozzles. 4. Fine Engineering: Designed with accuracy in mind, the 3D printer integrated nozzle features a slick inner wall with a roughness of Ra < 0.4, ensuring uninterrupted filament flow and minimizing the risk of clogs. The tightly fitted joints effectively prevent filament leakage during the printing process, contributing to higher print quality. 5. 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 melting process of the filament, resulting in finer print quality and reducing the chances of printing errors or inconsistencies.
