Welcome to the SeeMeCNC Community

Presently working on optimizing the 3D model for the bladeless fan. Some CFD shots will be printed in coming weekend.

Added 3mm tangential holes to see the flow affect.The CFD in progress ..

CFD reveals the holes worsen the flow pattern.

Nice!!!

Thanks, Due to intricacy in the geometry i have to split the air duct in 6 pieces. The first piece has been printed.

Very impressive! What application do you have in mind for this part?

Thanks, I am making Dyson Air multiplier.

I think I can figure a way to add that to the end of my hot-end.

That is a super-duper idea. You can find the STL here in the following Thingiverse link:

If you need to shrink any dimension let me know.

That's what I was thinking too! Kind of a hybrid Berd-Air system...

somehow managed to assemble all the six pieces of the duct.

interesting!
My first thought was for part cooling also.
"Berd-Air" powered of course

@Jim, so you going to have a scaled down one printed by Thursday evening so we can play with it at the MakerHive?


resin print it in one piece maybe?

Here is a little updates on the blade-less fan duct after primer application, lot of wet-sanding and finally spray paint. Check the glossiness... It just look out of injection molding machine.

Looks nice! I wish there were a way for us to see it in action. We'd need some kind of colored wind or something.

How about smoke from one of those electronic cigarettes?

or just a stick of incense

off-course smoke test as well as "Sewing Threads" hanging near the suction shall be tested to see the efficiency of the system. Presently designing 3D part for 40mm x 40mm x28mm computer fan duct attachment. Yesterday i just tested it with tap water to see the pattern of flow at the trailing edge which resembles with the results obtained from CFD.

How'd you fit it together? I have something like superglue for plastic, but the moment it touched it is perminantly attached... I'd imagine you'd want at least a few minutes of play to get everything lined up

Acetone works if it is abs.

I hear MEK or brakepad cleaner works if it is pla. But that is nasty stuff.
