Feature: 1. Wide Applicable: These 0.4mm nozzles featuring an all metal integrated design, can be quickly and easily installed on for K1C, for Ender 3 V3, for Ender3 V3 Plus, and supports PLA, ABS, PETG, TPU, PP, PC, PLA‑CF, PA‑CF, and PET‑CF filaments. 2. Premium Materials: The heat break is made of high tensile strength and toughness material, effectively reducing heat conduction, providing high thermal conductivity, hardness, and superior performance. 3. High Flow Printing: The 3D printers high flow extruder nozzles' body cavity is enlarged, generating a maximum flow rate of up to 30mm³ at a printing temperature of 240℃, supporting high speed printing up to 600mm/s. 4. Excellent Performance: The joint tightly fits, effectively preventing filament leakage. The interior wall is glossy for easy feeding. The nozzle has no burr, ensuring stable printing and a reduced risk of clogging. 5. Advanced Manufacturing Process: The nozzles' advanced craftsmanship results in smoother and more delicate print models, enhancing the output quality and precision.
