Product Features
  

         
High Thermal Conductivity360surround ceramic heater improves heating efficiency, more uniform heating and faster heat transfer. Ender 3 V3 KE hotend can be heated to 200C 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.
         
300C High Temperature ResistanceThis 3D printers ceramic heating block is newly upgraded. Upgrades kit can withstand high temperatures of 300C compared to the 250C 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 KitAll-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.
