- Dreaming ducts.. trying to find a better way. Is this it? Let me know in the comments.
It's not without its faults.. but I think I can design something that will work. This air is extremely good for layer cooling. It's only fault is.... How to remedy? I have some ideas..
This duct printed a near perfect 10:30 benchy and excellent 8 minute benchy with perfect bow. What was wrong with the 8 minute benchy?
This took many hours to design and many more hours with CFD to help me. Not perfect, not bad. I bet with CPAP it would blow the valves out! Going to find out!
Stay tuned.
I think this is one of the most important discovery of 3D printer community. Thank you.
Here before this fan duct becomes the new standard...🤫
Would really appreciate a GitHub with CAD or a Discord. Would really like to adapt this to my printhead and test it out with CPAP. Excellent work
Great idea! I will most certainly borrow elements of your design 😊 Thank you for sharing your ideas with the world.
Thank you for the explanation and education! Your making great progress and I can’t wait to adapt this to my printer . Cheers 🍻
I love some outside the box thinking. Man, in my pea sized brain it sure seems this could work great. I wonder if we thickened up the valve stem, and added say 3 smallish ports around it funneling some air straight down it could give coverage to those two center dead spots as well? Nice work!
I am not sure how this works yet. When I watch the water I see that possibly the 2 valves plus the 2 centers are moving the air out the front center. Almost like a garage with 1 entrance and exit and the wind flowing through on a hot summer day. So the 2 areas behind and in front of the nozzle might be getting cooling from the wake. This is definitely the best cooling I have had with any ducting I have tried.
Also, in my testing, there needs to be sufficient volume near the exit. When you neck it down the difference in pressure between ambient and duct causes a bottleneck and does not flow. But in the end, I will remove the valve and try and put into the print or make a nozzle that just snaps in. Still testing.
Is this a substitute for full layer cooling from sides?
I think dedicated layer cooling from the sides would give more air to the whole plate. However, it may be enough to print most things without layer cooling. Everything has limitation so I will explore this idea to see what progress can be made. Different valve types with different shapes. Just an idea I had to see what shakes out.
@@MrRocksalt I like it. I'm trying to work out best layer cooling for my delta, which doesn't admit fixed fan position for layer cooling unless you just want to cover the whole volume in fans (which I might do 😂)
what filament is this?
Black is ABS+, green is ABS.
all this air is from a single 5015 blower fan??!!
This test was with a 4028 axial fan. It's a cheap one, so with a better 4028 it would deliver much more air. I have not made this for a 5015 and I would expect similar results, but would need a smaller duct.
