E3D Dual Extrusion – Cyclops+ Air Cooled 1.75mm


Dual Extrusion+ Cyclops

The next generation of the E3D Dual Extrusion Cyclops, redesigned in 2018.  This hot end has two filament inlets and one filament outlet for experimental dual extrusion in a compact package.  

From E3D:

Same great printing performance and possibilities; new compatibility and features.

Cyclops Rework

  • The Cyclops heater block has had a complete redesign, improving performance and making it more adaptable. We’ve removed all unnecessary material, lowering the thermal mass and reducing heat-up times. By changing the outer architecture of the block, we’ve also reduced the amount of heat radiating down from the block onto the print. This makes it easier to print small, complex parts without the need for a silicone sock.
  • The distance between the filament paths is 2mm larger compared to the old-style Cyclops. This makes Cyclops+ compatible with the Kraken, for those looking to experiment.

Things to watch out for:

  • We recommend only using similar plastics when “mixing” using the Cyclops+ HotEnd.

  • 1.75mm bowden setups only


  • Chimera+ fit standard fans, thermistors and heater cartridges. It will also work with Capricorn bowden tubing
  • Chimera+ is compatible with cartridge-style heaters and thermistors, opening the door to PT100s and thermocouples.

Cyclops+ is no longer compatible with

  • Old-style Cyclops heater blocks

  • Old-style Cyclops and Chimera heatsinks due to the increased distance between the filament inputs

  • Bead-type temperature sensors

  • Due to the design change, this will not be compatible with some user designed mounts for the previous Cyclops or Chimera.
