1. QuickSwap: The integrated nozzle is suitable for Creality K1C, Ender 3 V3, Ender3 V3 Plus. Ender 3 V3 nozzle 0.2mm heat break is an allmetal integrated design for swift installation and easy replacement 2. Upgraded Material: The heat break is made of titanium alloy, which can effectively reduce heat conduction. The nozzle is made of copper alloy and hardened steel bimetallic material, high thermal conductivity, high hardness, better performance. Support PLA, ABS, PETG, TPU, PP, PC, PLACF, PACF, PETCF multiple filaments printing 3. Highflow Printing: 3D printer nozzle kit chamber is enlarged so that when the printing temperature is at 240°, the maximum flow rate can be up to 30mm3, supporting 600mm/s highspeed printing 4. Crafted with Ingenuity: Joints fit tightly and effectively prevent filament leakage. Smooth inner wall for smooth feeding. No burrs at the orifice, stable printing, not easy to block the material. The advanced processing technology makes the printing model more smooth and delicate
