3D-printed flutes hit new notes | Researchers have found a way to 3D print instruments that produce notes unattainable through traditional instruments.

Hand-crafted instruments are all well and good, but the precision of 3D printing is starting to unlock new sounds.

Leading a team of researchers from the University of Wollongong in Australia, Dr Terumi Narushima took the existing mathematical models used to determine how various notes are produced by wind instruments, and created a 3D model of a flute that – due to its customised diameter, length, and hole placement – produced unique microtonal notes smaller than a semitone.
