Genuine E3D Heater Cartridges A powerful little beast of a heater cartridge. Get rid of fragile and poorly toleranced enamel resistors and switch to a purpose made high power ceramic heater cartridge. Get your HotEnd hot quickly and hit the highest of temperatures. **Please check the power supply, mainboard, and manufacturer for the correct Heater Cartridge! High Temperature Heater Cartridges Planning on printing regularly at high temperatures? These 65W high-temperature heater cartridges are capable of operating at temperatures up to 550°C for extended periods of time. Ideal for high-temperature Thermoplastics such as PEEK or PEI. These cartridges have been designed for longevity at elevated temperatures whilst reducing heat up time. While most standard 3D printer heater cartridges will reach high temperatures, they tend to fail after short service lives. If you are printing high temperature materials and need consistent reliable service without downtime for heater failure this is the heater you need. Please note: These heaters are more than capable of reaching temperatures that will soften the aluminum block shipped as standard with the E3D heaters. These must only be used with a copper block. We also recommend coupling this with a plated copper, or Nozzle X, as the hardened steel nozzles will lose some hardness at these temperatures. Please ensure you double-check the power supply before choosing either 12V or 24V. Package Contents - 1x High Temperature Heater Cartridge, 1x Extension Cable
