The Flapper Drones are bio-inspired flying robots invented by TU Delft Aerospace Engineering team in the Netherlands. It flies by flapping their wings like birds and insects, and it is being developed for entertainment purposes. We collaborated with the team to apply HP’s Jet Fusion 3D-printing technology for making the robots more expressive and robust.

The 3D-printed external shells are designed inspired by a humming-bird, and it weighs less than 10 grams. In order to keep the light weight, it was designed to be perforated and printed in extremely thin layers. An anchoring mechanism is also integrated into the shell using living hinge designs, so the installation of it to the drone’s body is easy and quick.
