Best design for Flashforge Creator Pro fan duct?

lkauf · 2016-02-25T17:15:16.000Z

I printed and installed one similar to this. It works great! I did that once and never looked back.

There is a new version of this duct available at thing 537918 Anyways in case you decide to print this version here please carefully read the following information completely: This active cooling duct is designed to work on the following...

Hi,

I have a Flashforge Creator X and I’m using this design “Active Cooling Fan Duct” from thruit00 on thingiverse and it works very very well !!!

Regards

I’ve been using this: Makerbot Replicator 2x Filament Fan Duct w/Magnets!! by pwnate - Thingiverse

But I like the use of the squirrel cage fan…I might switch over.

I would suggest the one I made for myself, which is a remix of a remix of the rear cooling duct.

I consider it vastly superior to front fan designs as it takes a lot less space, it’s not as close to the extruders (no risk of melting), and the air flow is better.

Rear Active Cooling Duct v2 for FlashForge Creator and Makerbot Replicator 1...

I made a few modifications on the design, making it a tighter fit on both the printer and the cooling fan. No more need of tape, it sticks very firmly together. This also means that it's more difficult to install: you'll want to use a softer material...

I’m also running this one. Works like a champ! I just wired it to a transformer and plug it in when I want to use it. There is a way to wire it into the FFCP, but this way was just easier.

Go, Blue!

jasonk · 2016-02-26T01:16:42.000Z

Yeah, just moved here to the “homeland”. Designed and printed a set of coasters for my neighbors and they LOVED them. Easy to do with the FFCP.

Right on. I miss AA. I’ve got a lot of experience with my form1+ but am just diving into the Flashforge, which I bought last week. I’m hoping to one day understand purge walls as well as you to get such nice dual extrusion prints!

jasonk · 2016-02-26T03:25:04.000Z

Hit me up sometime and I can talk you through how I do it. Pretty easy. I use Tinkercad and Makerware. Also, I gave up on Abs. Just use PLA for now and enjoy the nice prints. Hatch box makes nice stuff… Message me your number if you want to talk sometime and I’ll share all my secrets… Lol. Take care!

Hi RiXnCo,

Thanks a lot for your suggestion. This design you are using (left below) doesn’t work with the round turbofan (right below) that comes pre-installed on recent models of FFCP. Did you put a rectangular fan instead to fit into the duct design? I presume one could just disconnect the turbo fan and buy a round one instead. It’s easier at this point though to go for a different design that uses the round turbo fan.

Ciao Vincenzo,

This design looks great. I agree with you that rear mounting makes more sense. It’s a little squeezed to mount a bed fan in front of the 2 fans that cool the nozzles.

In your description it says, you might crash into the bed support. Did that ever happen to your knowledge with standard, unmodified gcode. That would be dangerous for our machine, since we have multiple users that won’t know about this additional requirement.

Hi KuL3D,

I initially thought that this was a suction design reusing the 2 main fans and pulling in air to the top (left schematic). Now, that would have been a cool design. But as seen on the right it actually needs 2 additional fans giving us a total of 4 on the FFCP which seems a bit cumbersome. Thanks for the suggestion, though.

Hi lkauf,

A front fan duct for a rectangular not the round turbo fan. I presume your Flashforge didn’t come with the turbo, didn’t it? Seems like a waste not to use a duct design that utilizes the turbo fan if you have one installed already. The rear and font design will probably produces better airflow than the factory sideways duct.

I did a test run with the factory sideways duct and the difference is stunning. This will probably be my most important upgrade.

Hi Jasu,

I’ve a 2 years old FFCX and it did not come with any cooling fan system. So I googled and made up one from scratch following tutos and advices. This was a great improvement !!!

In your case, you could very certainly change the radial fan for an axial one and use the design I’ve pointed out.

Good luck in your quest

And let us know what you end up with. (Who knows I might buy a new FFCP in a near future)

Chris_Fullwood · 2016-02-28T19:49:24.000Z

I created a duct that connects the turbo fan to the active cooling duct design here http://www.thingiverse.com/thing:537918.

Works very well.

It does if you use the duct I made.

Printed this backside fan and have been using it for a few prints now. Tricky to print because the thin air tunnel needs internal support that is difficult to remove. Very easy to mount. Loosen the bottom screws, slide it in, click in the fan, and finished. No additional screw needed. I have also not experienced any collisions.

Well done. My favorite design off all the ones that I found an listed here.

Hi Chris, thanks for that. Didn’t spot it.

Hey Chris, have you any more photo’s of how that .stl looks fitted on the FF Pro please? Cheers, James.
