Micro-Drones That Are Completely 3D Printed (+VIDEO)
3D printing will surely revolutionize the way we shop, repair and invent things in the near future. Researchers from the Harvard University have created tiny micro-drones that are totally 3D printed and feature intricate technologies incorporated into them. They are as large as a thumbnail and can reach a wing flap frequency of up to 30 hertz (a frequency where you can no longer see the wing’s contours). The micro-drones are powered by an external power source, which makes them a little bit limited to where they can actually “fly.” They are 3D printed into a kind of ceramic, carbon fiber and plastic scaffolding that pushes the micro-drones up, releases the lock mechanism and finally releases the bee micro-drones. Future applications of these artificial bees are not clear at the moment, though it may be assumed that they could be used for recon missions, tight space repairs and a whole lot of other endeavors. The manufacturing process of the micro-drones is demonstrated in the video below.
