When you look at a 3D printer, your first thought might be about producing useful components. However, hearing an air raid siren can evoke memories of historical reenactments.

I belong to a different group of people; upon hearing a 3D-printed air raid siren, I imagine a future apocalypse. Bear with me;

Youtuber Mark Makies has designed this fascinating 3D printer siren, known for its unique blend of playful resonance and foreboding sound, reminiscent of both a beloved children’s show and a grim warning siren.

This project uses a combination of bright 3D-printed components and remote-controlled parts to create an enchanting yet alarming sound experience.

Internally, a brushless motor drives a rotor that modulates air pressure through a stator, creating a chilling sound that may send shivers down your spine. The pitch can be adjusted, evoking pleasant memories along with a tinge of fear.

I recall my youth in a small town near London, where a WW2 air raid siren would alarm me from sleep every Tuesday. To this day, no one knows its purpose, sparking lively discussions during afternoon drinks.

This video takes me back to those simpler times. I wonder if I will hear such a siren again, hopefully in a more colorful context.
