Usage Tips:High temperature printing, long service life, stable connection, fast disassembly, reduce plugging phenomenon, improve printing quality, can effectively reduce the phenomenon of leakage consumables and falling off. 260°C High Temp Printing, All metal titanium alloy is high-temperature resistant and can support various filaments, such as PLA, ABS, PETG, TPU, PP, PC, etc. Upgrade Bimetal Heat Break, The combination of chrome-zirconium copper pipe and titanium alloy pipe heats faster and higher, and the heat dissipation is better. Compatibility Suit for Creality Ender 3-V3-SE. Heat break and nozzle inne! wall roughness Ra≤0.4um. Printing Speed Up to 250mm/s, for Ender 3-V3-SE assembled extruder hot end kit has been assembled in advance, all you have to do is plug in the wires. Nozzle diameter: Brass 0.4mm Heat break wall thickness: 0.5mm Internal roughness of throat nozzle: Ras0.4um Consumable diameter:1.75mm Heating rod voltage power: 24V 40W Heat sensitive type: NTc 100K, maximum temperature 260℃ Applicable model: FOR Ender 3-V3-SE Color: silver Material: Aluminum alloy + chromium zirconium copper + titanium alloy Package Contents: 1 x Hotend Kit Only the above package content, other products are not included.
