That's cool, but I guess it is still cheaper to order them lol

It's a great indication on how the future will be. Just browser and click on a object, and some time later it comes out of the printer.

But frankly, I am having a hard time trusting the current 3D printers for something as sensitive as a propellers. You would not believe the amount of strain a propeller has to endure during flights.

John, I agree.  It's a really interesting concept, and I'd love to be able to make my own props that are custom designed for a multi-rotor.  Similar to those nice CF ones you got, but in 12".  But I also really question how strong they'll be.

Better yet, 3d print the mold! (laser sintered metal anyone?)

for that kind of shape a cnc router seems to be a better option

It is some time that I use my makerbot thing o matic for some parts of my quadcopter. First some minor parts, then i've discovered that ABS can be used for almost everything if used properly. Now i'm testing light motor Mount (quad auw weight is 1.4kg!) long life to 3d print!! :)

Wow is this a bad idea.  The cross section of 3D printed parts is very inconsistent.  The parts are very weak especially with thin walls.  Please note in the video that the camera is lined up perfectly so that the camera man has every chance catching a part of a broken prop in their face.
