E3D Revo HeaterCore-24v

The E3D Revo HeaterCore is a heating and sensing architecture for E3D’s RapidChange Revo ecosystem. It is a powerful cartridge heater and thermistor that replaces the traditional aluminum heater block. The HeaterCore secures onto a Revo-compatible cold side using a Revo HeaterCore spring (included). It heats up much faster than a typical heater block, and it reaches temperature much faster than a traditional aluminum HeaterBlock. It is much safer than a traditional aluminum HeaterBlock because of its positive temperature coefficient (PTC), which means the HeaterCore can’t melt at extreme temperatures, reducing hazards in the event of a thermal runaway. The Revo HeaterCore is available in various sizes, including 40W, 60W and Creality CR.

Compatible with many popular 3D printers such as Creality CR series and Ender series, Prusa, Anet, Biqu, Monoprice, and many more.

Check the E3D 3D printer upgrade guides for more information.
