POLISI3D Plated Copper Heater Block High Temperature Ender 3 Heat Block Compatible with MK8 Extruder Ender 3 V2 Pro Ender 5 Plus CR10 S4 S5 3D Printer All Metal Hotend Upgrades

Brand: POLISI3D

Features:

• It is designed to fit two types temperature sensor -OD3mm High Temperature cartridge sensor and normal type sensor;no obstruction in heat conduction to the nozzle. Only 21.2g, Remove unnecessary parts in the design to reduce the weight of the heating block, and increase printing stability. And The orignal CR silicone cover also fits this block (Silicone cover is not included here)
• Package: 1piece heater block with set screws. Compatible with Creality ALL Metal Hotend Ender 3s Ender 3 pro Ender 5 Pro CR10 S4 S5 3D Printer and MK8 MK9 extruder
• The heating block has groove gaps at the connection of the throat on one side, which can reduce heat conduction to the throat and reduce blockage.
• Material: Copper alloy; It is machined with very high precision and high quality.This copper-alloy is very temperature resilient, and will not start to soften or anneal until way beyond 500°C, making it perfect for the high-temperature printing
• Copper has more than 3x the thermal conductivity of brass, and the copper alloy we use has been hardened and treated to reduce the oxidation that occurs in copper at high temperatures. The higher thermal conductivity will also slightly increase your heat-up times, and can provide tighter temperature control.

Details: Package: 1piece heater block with set screws.
