Hey guys, I'm looking for advice or suggestions about watercooling my Delta printer. I'm using it to experimentwith very, very high speed printing. It's going to have a heated chamber with a max most likely around 90C.

At these temps, my fan on E3DV6 is insufficient, so I need to either to resort to watercooling or having cool air funneled in. I've decided to go with watercooling.


I'm not sure how much watercooling I'll need. I'm going to drive my stepper drivers at higher currents (2A, can I push it further? Or diminishing returns?) to get the most out of my NEMA17s to get as high as accelerations as I can so I will be watercooling an E3DV6 hotend, 3 NEMA17s, the smoothieboard stepper drivers, and at least 2 Extruders inside of the chamber (Floating Extruder setup).




I haven't convinced myself on what kind of water pump i'll use. I have thought about the Kraken hotend pump


Filastruder Waterpump



,but it's only 240L/hr and was not designed with a heated chamber in mind with multiple components.


The rest of components will draw from PC watercooling components, a waterpump/reservoir combo, and generic waterblocks (aluminum) and an RC waterjacket for the E3DV6.


I'm trying to keep all the parts in the loop aluminum due to galvanic corrosion if I introduce other metals. I'll be using a biocide to prevent algae growth which I haven't seen anyone who has done watercooling for 3d printing mention, distilled water, and most likely an anti-corrosive mix just in case since I may not be able to find an aluminum radiator block for cheap.


Now about the radiator block, this is the most important of the loop because it controls how much heat transfer is possible. In the PC world, it is recommended to have 120mm for each component (CPU, GPU, etc). Now, our 3D printer motors don't usually get to that temperature, but with such a high temperature chamber on the extruders, it may be necessary to use a 240mm radiator (I don't mind, the delta printer will be quite large, relatively). I just want to avoid so much cooling that the hotend can't do its job properly (which is my largest worry).




Any tips or critiques are very welcomed. Thanks and Happy Holidays.
