8040 Propeller Optimized for Printing, V1.0 by Landru Sep 12, 2012

Featured Thing!


This is a redesign for an 8040 printable propeller with a 5.5mm (13/64") bore.

This prop was designed to keep the minimum cross section above .8mm allowing it to be more easily printed, though at a small efficiency loss.

The propeller will require support on one edge, which makes it very easy to remove.

I can redesign this for some different center hole diameters if requested, just give me some time as I am pretty busy.

Here is a short video with the prop on a motor: youtube.com/watch?v=v6yClT12Ges&feature=plcp
I will also be uploading a 5030 prop once it is flight tested.

I printed mine on a Fablicator using Kisslicer.

Waiting for 5030(R) props :)
This is great! would you be able to make a 4.5x10 prop?
have you had the chance to test them yet? please tell us how they worked !

I suggest using 2-3 shells, 100% fill, and a layer thickness no larger than .2mm (I used .17mm with excellent results.) I also used an extrusion width of .4mm

The propeller will need support material enabled.

I highly encourage printing this from PLA, since the thermal contraction of ABS will often warp/crack the blades.

Once printed, remove the support, ream the hole to 13/64", and sand the edges a bit to remove any leftover support or jagged edges.

I've spun this up on a 1300KV hextronic 24g brushless outrunner with a 2S lipo and it puts out some pretty impressive thrust. The propeller feels every bit as strong and durable as a bought one (Though I have not crashed it yet)

I've uploaded a few different orientations as well as CW/CCW Pairs for easy printing.

Printed these out with a .5mm nozzle. settings are as follows in Kisslicer
Skin Thickness - 1mm
Loops - 2
Infill - 100%
Extrusion Width - .55mm
Infill Width - .55mm
Layer Thickness - .152mm
Material - Red PLA
Loop Speed - 15
Prop came out really nice, cant test them yet because i am still waiting on my motors and other parts from HK. Will definitely post on them.
Thanks for the files

Thanks for sharing this propeller file. It works really nice!

I really like your model. I'm looking for a 1047 (10x4.7) prop model. Would you be able to model that one? Need it for a heavy lifting quad.
Can you include the Solidworks file? I would very much like to see it :)

I'm really surprised how well these turned out!  I was hesitant to try these on a real quad, but 4 of them lifted my overweight quad just fine.  

So far, they've proven to be just as robust as store bought props.
What did you model this in?
I have printed a quad copter, and I love the idea of printing the props as well.

What is the difference between the different files? Other than clockwise and counter clockwise (CW and CCW) I have no idea which is which. Which should I print?
Some are horizontal, and some are rotated 45 degrees for fitting on a build platform better. They are all the same Propellers (either cw, ccw, or one of each)

My file names are a bit more descriptive in full, I see they have been cut short.

Both of the first two files have a both a cw and ccw propeller on the same plate. I suggest you print one of those.
Did this require much balancing?
It doesn't seem to vibrate any more than a normal prop, but those likely 'need' balancing too. It will depend on your printer and support removal skill in practice.

TLDR: Probably
Please post a follow up if/when you a blade gets hit in a crash - I'm very curious how the printer blade reacts. I've seen normal props break and I'll bet printed blades react very differently - will strands of filament delaminate and spin around? Will broken prop pieces spin around instead of flying off?
Well, I broke some experimental 5030's. They snap off cleanly near the hub, no delamination. I expect these to do the same.
Is the 5030 prop available?  I need some 5030 and 5030R's for a quadcopter...
I'd definitely like a 5030 for for the little quad im building. Hopefully you can work the kinks out of the design
I have been unable to make a good 5030 size so far. The bough ones are far superior. FFF just doesn't lend itself to very thin walls, especially for a good airfoil. 
I have a printer that is capable of 0.050 layer heights, which may make a 5030 printable. Would you consider modeling a 3-blade 5030 prop for me? Your design is the only blade I've gotten to print reliably, and works well.
I'd like a 5030 too. Infact I'd even like a 4020! My nano-quad needs new shoes, um props...
