This research considers the controversy of modern acoustic instruments, which may have come to an evolutionary impasse, due to its high standardization that makes it difficult to explore design modifications. I explore a new approach for the design and fabrication of the acoustic instrument, using 3D printing, which has the potential to influence new designs, and to lead to new acoustics and ergonomic innovations. The projects below describes the key concepts of this approach, presenting the development process of such a 3D printed instrument—a prototype of a 3D printed concert flute, some other concepts for 3D printed instruments.

The 3D Printed Flute

The goal here was to create a flute using 3D printing technologies – a flute that is compatible with a traditional concert flute, both acoustically and ergonomically. This flute is composed from several materials - a rigid material was selected for the flute’s body, a different one for the mouthpiece, and a soft material for sealing the air properly. Only springs were added manually later.

This project was fabricated with the Objet Connex machine, which can print multiple materials in a single build. The overall process took around 15 hours, creating 4 separate parts that then were assembled to a working instrument. The first step of the process started with a CAD software design, building a digital model of the flute in the computer, and totally re-designing its mechanism to so no assembly will be needed after print, and to fit the abilities of the 3d printer. Then, the final design was sent to the Connex machine, which simultaneous jets of multiple model materials to create composite Digital Materials™ on the fly.

reAcoustic eGuitar
reAcoustic eGuitar is a concept design of an instrument that enables players to customize their own sound by assembling different sound cells instead of a single large sound box. Each string will have it’s own bridge, each bridge will be connected to a different cell. changing the cell size, material or structure will allow sound design innovations, re-designing acoustic musical instrument according to the abilities and characteristics of rapid prototype materials.
