Water cooling does make for a quiet machine but at the cost of fitting extra tubes and a cooling system. Even if you want only a single or dual head machine, I would still recommend the Kraken if you want to experiment, for fitting it to a machine like the Prusa i3 it’s easy and everything can be made neat. I ran the Kraken at full temperature for 4 days printing constantly, it never once caused a single print issue or skipped a step. Kraken assembled on Prusa I3
1. It’s experimental! Great for PLA printing. (1.75mm Bowden) 2. Great for multi colour prints and material experiments. 3. Quiet and compact. 4. Has it’s own mounting system - printed mounts will usually be required to fit to most printers. models using PLA.
