Axial Fans are a bad application for this. Generally you need to limit yourself to around 11 degrees of air "bend" to get good flow. If you have more than that, typically you want a radial (squirrel cage) fan for this as they put out more static pressure. This allows it to overcome the pressure gradients necessary for good flow at the tip of your airflow exit.
You'll likely experience sub-par performance with this setup. You've got good design skills though!
Thanks, still learning all the features of fusion 360, but I’m getting better ;)
Actually I am experiencing pretty perfect prints with this setup right now (perfect for me) and I can actually feel the air flow where it’s supposed to. But see and decide yourself :) Here some examples in different materials already printed with this type of fan setup
Victorinox Scales in PLA:
You maybe saw my first TPU iPhone case in this community, here is another design (made by myself this time):
First layer side of a shelf I printed recently in PETG:
The fan flow issue will show itself in much larger parts eventually. If all you're doing is printing thin walled boxes, it'll probably be okay. You're already proficient in Fusion360 I'd say!
Thank you! I am trying my best to get even better :)
Hmm… okay, that’s a point. I will have to try that someday and test how my fans are going to handle that. Indeed I never printed something over 24 hours print time. Mostly I need only smaller parts for around the house, in car or something like that. It’s very uncommon for me to print something like figures or decoration that takes that long to print. My decision to change the fan setup was pretty simple. I needed my printer to be quiet so that I can print at night (when the baby is sleeping). The stock fans were so loud you could hear the printer with closed doors a few rooms away. So I knew Noctua are quiet, but they don’t make the type of fan normally used for part cooling. So I came up with this solution (or gen1 of this to be more precise as this here is already gen3).
