Features: This Sprite extruder heater block kit is compatible with Creality Ender -3 S1 or Ender -3 S1 Pro or CR -10 Smart Pro or Sermoon V1 or Sermoon V1 pro 3D printer. The heating block is made of nickel coated copper. Our copper alloy has been specially treated to reduce oxidation at high temperatures and ma more than 3 times the thermal conductivity of brass. This results in faster heating times and better temperature control, allowing printing at temperatures do 550C, which is ideal do printing at high temperatures. Capable of do continuous operation at 300, compatible with high-temperature fibers such as ABS and nylon, allowing greater creative possibilities! Fast heating enables faster printing!
