SIMULATION BASIS: MASS-SPRING-DAMPER MODEL (HOOKE’S LAW)
PHYSICS ENGINE: NEWTONIAN DYNAMICS // F = -kx

MATERIAL AS FILTER

DENSITY VS. STRUCTURE

In organ building, material is not a passive carrier but an active equalizer. Lead (Pb) utilizes its extreme density and softness to dampen overtones—acting as a low-pass filter that lends weight to the sound. In contrast, we have generative structures from 3D printing. They possess almost no mass but achieve high stiffness through their geometry. Here, vibration is not absorbed by mass but permitted and shaped.

FROM SIMULATION TO CONCERT HALL

With the organ at the Helsinki Music Centre, this experiment has left the simulator. Through the world’s first application of 3D printing for sounding façade pipes and visible wind systems, the digital structure was successfully transferred into physical reality.
