1、UPGRADED CERAMIC HOT END KIT: This standard flowrate nozzle use a unique custom internal geometry to increase surface area and thus improve heat transfer to the filament. And increasing the volume flowrate of the Settings allows you to print faster 2、STRONG MATERIAL: The nozzle is a pre installed nozzle and HeatBreak combined into one, using three metals, the tip is hardened steel, the inner tube is Ti alloy TC4, the rest is Cr Zr copper material, with different thermal conductivity 3、EFFICIENT AND UNIFORM HEATING: The ceramic heater has a more uniform heating effect than conventional heater cartridges and can quickly rise from room temperature to 200℃ 4、PRINTING TEMPERATURE: All metal hot end supports printing at 300℃, making it suitable for a variety of filaments, such as PLA, ABS, PETG, TPU, PP, PC, nylon, etc. 5、TOOLLESS NOZZLE CHANGE: Easy to install the ecosystem allows you to change nozzles in 30 seconds at room temperature without the need for tools. The hotend is designed to be easy to install and takes only 30 seconds to complete Item Type: Ceramic Hot End Kit Material: Hardened steel, Ti alloy TC4, Cr Zr copper, ceramic Material Compatibility: Approx. 1.75mm / 0.07in Voltage: 24V Power: 40W Maximum Temperature: ≤300℃ Compatible Filaments: PLA, ABS, PETG, TPU, PP, PC, nylon Applicable Model: For BIQU H2 V2S, for Ender 3, V2, Pro 1 x Hotend 1 x Feeding Tube 4 x Screws 2 x Connection Cables
