Working 3D printed Helicopter Blades

thingiverse

Revamping complex machines like helicopters using home 3D printers has been an idea that's been tossed around. Could one actually produce a working helicopter on a home 3D printer? The key component would be the blades - they must be thin, lightweight, smooth and strong. If not, there's no making a helicopter. But guess what? You can! However, do these printed blades actually work without falling apart when spun or generating too much turbulence to fly? Check out this video: http://www.youtube.com/watch?v=qXlUSWrVzys to see it in action. The helicopter used is the "JXD 340" or "Drift King," an affordable $30 toy that's better than most cheap helis on the market. Here's a link: http://www.amazon.com/Indoor-Infrared-Control-Helicopter-Gyroscope/dp/B004OGBNJ8/. Safety note: PLA is used for printing due to its sticking ability and compatibility with small layer heights, but it's brittle - be warned! When these blades break, they tend to shear off and send a sharp piece flying. Cut throttle power when about to crash to reduce blade spinning energy. Remember, print at your own risk. Want source files? They're available in Solidworks 2012 format, with both blades (A and B) provided for the "JXD 340." New smaller blades have been added that seem to make the heli fly faster. Print blade upside-down from flying configuration to avoid overhang issues. PLA is recommended, but ABS may work.
