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

Featured Thing!

Description

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.

have you had the chance to test them yet? please tell us how they worked !

I'd definitely like a 5030 for for the little quad im building. Hopefully you can work the kinks out of the design

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

Instructions

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.

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 :)

Thanks!

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?

Landru on Oct 15, 2012 said:

Solidworks

laird on Sep 14, 2012 said:

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?

Landru on Sep 14, 2012 said:

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?

Landru on Sep 14, 2012 said:

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

jkeegan on Sep 13, 2012 said:

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?

Landru on Sep 13, 2012 said:

Well, I broke some experimental 5030's. They snap off cleanly near the hub, no delamination. I expect these to do the same.
