Biocomposite organ

The organ features 3D-printed sounding pipes and wind lines totalling 260 meters. With 124 sound registers divided among several different sets of pipes, it is the largest in Finland and Scandinavia, among the largest in Europe, and the largest modern organ placed in a concert hall worldwide.

Helsinki Music Centre’s organ is a result of international collaboration. The biocomposite material produced by UPM in Finland was shipped to Burgos, Spain, for 3D printing.

Subsequently, the printed pipes were transported to organ builder Rieger Orgelbau in Austria. The organ was initially handcrafted by Rieger Orgelbau, disassembled, shipped in parts to Helsinki, and then reconstructed in the Music Centre’s concert hall.

The unique design of the facade pipes necessitated finding suitable material and a reliable, flexible, and cost-effective manufacturing method. The fine cellulose fibres in the biocomposite facilitate large-scale 3D printing, and the material’s minimal shrinkage, rapid cooling, and self-sustaining properties enable efficient production of complex elements.

3D-printing generates minimal waste, and the wood-based biocomposite is 100% recyclable.

Biocomposites inherently possess acoustic qualities, commonly used, for example, in speaker enclosures.

“The organ sounds magnificent. It’s wonderful to open the concert hall to the public and enjoy both the music and the visual experience that our new organ and performers will provide starting from January,” said Kaisa Näreranta, Executive Director of the Helsinki Music Centre Foundation and Project Manager of the Organ project.

The Helsinki Music Centre Foundation initiated a naming campaign for the organ pipes, raising funds for organ music, producing organ programs, and events. UPM contributed to the campaign through its Biofore Share and Care program.
