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: http://www.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.

May be do you have 8045? Or something a little change your project 8040 and add to your collection that size.
I am impressed, Well Done, Question, I don't know how to use Solid Works, Can you draw a prop design that would have a ring around the blades in hopes to make the fans quieter, I have a Maker Bot printer, and I thought a quieter design would be great, I have a DJI Phantom FC 40 Quad , Just starting on it now, Thanks Bill
Hi

printed these props for my dji F450, and im just amazed that it works^^

Heres a Video of these props i action

Great design!

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.

Hi,

I found this STL for 10x47 propeller with correct aerodynamics. But i guess it requires some modification to be 3d printable. Can you take a look at it? http://grabcad.com/library/10x4-dot-7-propeller

Thanks

Waiting for 5030(R) props :)

This is great! would you be able to make a 4.5x10 prop?

<p>Printed these out with a .5mm nozzle. settings are as follows in Kisslicer<br>Skin Thickness - 1mm<br>Loops - 2<br>Infill - 100%<br>Extrusion Width - .55mm<br>Infill Width - .55mm<br>Layer Thickness - .152mm<br>Material - Red PLA<br>Loop Speed - 15<br>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.<br>Thanks for the files</p>

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

<p>Thanks for sharing this propeller file. It works really nice!</p>

<p>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.</p>

<p>Can you include the Solidworks file? I would very much like to see it :)</p>

<p>Thanks! </p>

<p>Posted! </p>

<p>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.  </p>

<p>So far, they've proven to be just as robust as store bought props.</p>

<p>What did you model this in? </p>

<p>Solidworks</p>

<p>I have printed a quad copter, and I love the idea of printing the props as well.</p>

<p>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?</p>

<p>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)</p>

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

<p>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.</p>

<p>Did this require much balancing?</p>

<p>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. </p>

<p>TLDR: Probably</p>

<p>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?</p>

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

<p>Is the 5030 prop available?  I need some 5030 and 5030R's for a quadcopter...</p>

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

<p>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. </p>

<p>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.</p>

<p>I'd like a 5030 too. Infact I'd even like a 4020! My nano-quad needs new shoes, um props...</p>
