E3D's Kraken Hot End is the multi-nozzled, water-cooled, Bowden-fed, plastic-extruding monster! It uses standard V6 heater blocks and nozzles, which means that you can upgrade it with E3D's wide range of nozzle sizes and materials. Available in 12V only


Four Inputs, Four Outputs

Four times the printing power.


Modular Ecosystem

Fully compatible with E3D's range of blocks and nozzles to suit your every need.

Temperature Control

Water cooling is the next step in 3D printing, helping to keep HotEnds hot and heat sinks cool (just as they should be).

Bring out the Beast

Four complete HotEnds in one. Each nozzle is individually temperature controllable, and individually bowden fed. Kraken remains a compact and lightweight package despite its capabilities by using hyper-efficient water cooling, and innovative integrated bowden couplers that are contained within the body of the Kraken. Kraken has the ability to individually adjust the height of each nozzle and can, in fact, almost level itself using the bed as a reference.

01. Possibilities

Kraken pushes the boundaries of 3D printing by allowing you to use 4 distinct colours in a single print, 4 separate engineering plastics in a single part, or explore complex geometry by using soluble or breakaway support materials.

02. Requirements and Expectations

Although Kraken is now a mature and well tested hardware product with hundreds in the wild and a great deal of excellent community feedback it is worth keeping in mind that the Kraken requires a certain level of work and learning to get running. A working knowledge of firmware configuration, slicer settings and electronics is essential.

Kraken requires an electronics setup that is capable of driving 4 distinct extruders, so far we have had great results and feedback with both the Azteeg X3 Pro and the RepRapPro Duet with DueX4 expansion.

The Kraken is a powerful but tricky beast that requires a fair amount of engineering and 3D printing know-how to use effectively. Please read the product description and documentation carefully before trying it out. Additional support is available on the E3D forum.

We are currently selling the Kraken as a fully loaded kit, which contains all the machined hotend parts, thermistors, heater cartridges, bowden tubing and couplings, and a water cooling pump with tubing. To complete the setup you will need 4 Bowden extruders of your choice, and a reservoir for the water pump to sit in.

Component Weights:

  • Heat Break: 3.25g
  • Barbs: 2g
  • Cooler Block: 59g
  • Heater Block: 7g
