Creality Ender 3 V3 SE/KE Hotend, KE Ceramic Heating Block Kit with Quick-swap Nozzle, Accessory Upgrade Hotend 300℃ High Temperature 600mm/s High-Speed Printing for 3D Printers

【High Thermal Conductivity】360°surround ceramic heater improves heating efficiency, more uniform heating and faster heat transfer. Ender 3 V3 KE hotend can be heated to 200°C in 40 seconds 【High Flow Printing 】Ender 3 V3 SE ceramic heating block with enlarged nozzle chamber, achieves a maximumflow rate of up to 32 mm3/s, and supporting high-speed printing at 600 mm/s 【300°C High Temperature Resistance】This 3D printers ceramic heating block is newly upgraded. Upgrades kit can withstand high temperatures of 300°C compared to the 250°C that ordinary heating heads can withstand. At the same time, heat dissipation part featuring a split design for reduced heat transfer, the red copper heat sink enhances cooling efficiency 【Quick-swap Nozzle Kit】All-metal integrated design for rapid assembly and disassembly.reduces heat conduction. Ender 3 V3 SE nozzle is composed of copper alloy and hardened steel, supporting the printing of various filaments. Ender 3 V3 KE nozzle head is made of hardened steel (SKD11) material, with a Moh's hardness of 7.8, to provide a sixfold lifespan
