Dual Fan Duct (anular cooling system)


Recommended Posts

Posted · Dual Fan Duct (anular cooling system)

So, I was looking for a good system for a double fun duct, I ended up only finding one that I liked, I printed it, and It was for 40mm fans not the original size fans that the ultimaker comes with (50mm)

So I've made a remix of one I've seen in thingiverese,

Its a Design made for anular cooling system.

I don't know which are the best options for cooling with two fans,

Any suggesitions in the design or any other design out there that its good will be welcomed!

    Hi Alnavasa,

    the design looks pretty good. Which program did you use to create it?

    The original Ulitmaker fan does not supply enough cooling. I tried one simple fan duct, printed it out of PLA. Worked well at the beginning, but during an 30 hour print, the aluminium plate on the hot end got to hot so the duct was deformed, bent down and collided with the print and touched the printhead. So when I came back I had a ruined print and a half molten fan duct.... I would strongly recomend to print this out of ABS.

    I went back to the standard fan for one week, then I tried foehnsturms idea of the cross flow fan. Which works great for PLA. Best prints I did until now. Very simple. I love it.

    But I am also very interested to hear how your cooling system performs. The cross flow fan has a small problem with overhangs on the lee side of a print and it is louder than a small fan.

    All the best,

    Philip

    I'll Probably print it today or tomorrow, I am rewiring the heated bed connections of the UM, I need to do some soldering right now and I have the Machine sideways.

    But I would like someone with experience tells us what they think about the design.

    I model with Rhinoceros (free for mac (Beta version) and free for windows (trial version))
