E3D Revo™ HeaterCore (24V and 12V Core) (40w)


Voltage: 24V
Sale price$31.99


  • The HeaterCore secures onto a Revo-compatible cold side using a Revo HeaterCore spring (included). After it’s attached, just screw in a Revo Nozzle and you’re ready for simple, tool-free nozzle swaps that don’t need hot tightening.
  • Heats up much faster than a typical heaterblock. It’s designed to be much safer, too – a positive temperature coefficient (PTC) means power reduces as it gets hotter, reducing hazards in the event of a thermal runaway.
  • Compatible with many popular 3D printers such as Creality CR series and Ender series, Prusa, Anet, Biqu, Monoprice, and many more. 
  • Learn everything you need to know about the Revo HeaterCore in E3D's blog.
