Planning a new filament cooling system for my E3D Titan + E3D V6 setup.
My plan is dual radial fans (same as used on Bulldog Extruder)
A wall in the front and rear of the duct, so each fan generate airflov for each side of the “donut”
What do you think?
Not 100% ready yet
I’ve thought a lot about this and I’ve come to the conclusion that it would be nice to do with a single fan. I’ve run dual fans for a while and it can actually be too much sometimes. It’s very important to ensure precise airflow and ideally one should isolate the heater block (I highly recommend using a cast silicone “sock”). I’m now working on a dual carriage machine and in that configuration X space is very precious so this kind of setup would not work. I like the way some people have the fun/duct mounted on the back of the carriage, as it also makes it a lot easier to see the nozzle.
I can regulate fan speed from 0-100% so that should be ok.
I was doing that too, but in the end I came to realize that having two fans is just extra weight. Every gram you add to the carriage decreases print quality/speed.
Right, will work great with just a single fan if the ring is designed to direct the air out better. This is the cooler I use on my printer and works great. He even did an air flow study and it comes out like a tornado and cools from all sided. Plenty of airflow with a 50x50x15mm fan.
I made a housing that protected the heater block from blower air currents, and insulated the parts of the nozzle away from the orifice with high temp silicone. I have 2x 4020 centrifugal blowers and the results were spectacular.
