Features: Stable Structure and High Heat Dissipation - The water-cooled heat sink is made of aluminum alloy, equipped with a water-cooled circulation heat dissipation module, and the heat dissipation efficiency is increased by 30%, preventing printing from clogging. Ceramic Heating Ring - The cylindrical ceramic heating ring heats up faster and more efficiently, and it only takes 40 seconds to reach 200°C from room temperature. High Flow Support High Speed Printing - The overall hot melt section is increased by 30%, supporting 300mm/s high speed printing. All Metal Heat Break - The heat break is made of titanium and copper alloys which supports high temperature printing at 300℃ and is compatible with more filaments. Longer Service Life - The heat block and heat sink are perfectly fit through the titanium alloy base to avoid pressure between them, and the strength is upgraded to extend the life of the hotend. Material Upgrade for Better Printing - The heat block and nozzle are made of copper alloy, and roughness of RaO.3 on the inner wall of the nozzle to improve print quality. Lightweight Design - Modular standard interface design and lightweight, easy to install, compatible with most printers on the market such as Ender-3 Pro/Ender-3/Ender-3 V2/Ender-5/Ender-5 Pro/Ender-5 Plus/ Ender-3s/Ender-6/Ender-4/Ender-3 Max/Ender-2 Pro/Ender-2/CR-10S CR-10/CR-10 S5/CR-10 S4/CR-10Mini/CR-20/CR-20 Pro.
