3D Printing Reproductions of Indigenous Instruments in Museum Collections: Ethical Replication and Acoustic Sovereignty

This article examines the ethical, technical, and cultural dimensions of creating 3D-printed replicas of Indigenous musical instruments in museum collections. It centers on a prototype reproduction of a 19th-century Kiowa courting flute at Brown University's Haffenreffer Museum of Anthropology. The purpose of this project was to explore how digital replication technologies such as computer tomography (CT) scanning, modeling, and additive manufacturing can support Indigenous-led cultural revitalization while respecting community protocols. Drawing from sound studies, ethnomusicology, museum studies, and organology, the research advances the concept of acoustic sovereignty: the right of Indigenous communities to determine how, when, and whether their instruments in museum collections are sounded, shared, or withheld. Findings highlight the limits of technocratic approaches to replication. While the digital replica achieved acoustic functionality, the project prioritized ethical accountability over sonic demonstration. This commitment was modeled publicly at the Royal College of Music's 2024 “3D Printing and Musical Heritage” symposium, where the Kiowa flute replica was presented but not played, pending Indigenous community consent. Instead, a 3D-printed replica of a tourist-grade Native American flute was used to illustrate the replication process without violating cultural protocols. This article foregrounds Indigenous sovereignty in replication practices, in contrast to Western classical approaches that prioritize historical accuracy and acoustic fidelity for replicas. In Indigenous contexts, replication must also be rooted in consultation, relational accountability, and cultural protocols. The study concludes that ethical replication is not simply a technical process but a relational and political act. When Indigenous-led, and carried out collaboratively and with care, replication can support community authority, challenge museum norms, and open new pathways for cultural resurgence and repair.
