3D print your insect UAV wings


Excerpt from the New Scientist article: "While several research groups around the world have demonstrated flapping machines, wing design can be hit or miss because it's hard to get your head around the physics, says Lipson. This is where 3D printers come in – by shedding light on flight dynamics they could be an important step towards the development of smaller and more efficient wings, say Lipson and his colleague Charlie Richter.


What's so special about 3D printers? They make it possible to create complex structures, such as wings that are warped to improve performance, like the manually curved wings of a paper aeroplane, says Richter. Their printer is capable of producing features just 16 micrometres wide, and thin films just 40 micrometres thick.


The other advantage of printing is speed, says Lipson. Once they have arrived at a new wing design, printing a set takes under an hour. With the exception of its motor and battery, their latest four-winged creation is almost entirely printed from polyester films stretched over carbon fibre rods, and weighs in at just 3.89 grams – a six-fold weight reduction on their previous version – and capable of hovering untethered for up to 85 seconds.

  • Yes, I also believe in the 3D printing movement. I got my Cupcake CNC last week, and I will hopefully have it all together by this week. Started to use Sketchup to desing my UAV. Will be posting up soon...

    Chris, hows your makerbot doing? running to any issues?

    Thanks,
    Armando M.
