E3D Kraken - V0 (prototype) For the size and weight the Kraken is amazing! - itâ€™s a one to four Bowden fed nozzle hot-end with a water cooling system. Each nozzle is independent, so this is ideally suited to multiple materials, separate support material printing and printing multiple colour objects.
This is the best multi-nozzle setups I have ever used, and I have painstakingly calibrated quite a few over the years for people. All the nozzles can be aligned flat, together and tightened with just an Alan key. Kraken assembled nozzles
My Kraken has a 3D printed PTFE tube clamp, the production Krakenâ€™s have a standard style push-to-lock fitting inside the cooling block.
