Aectual Introduces Mass-Customizable 3D Printed Acoustic Diffusion Panels in Collaboration with Architectural Design Group, Gramazio Kohler Research ETH. Made from 100% circular plant-based plastics, the made-to-measure 3D printed acoustic diffusion panels merge acoustics with aesthetics to reduce naturally occurring reverberation that occurs in any room.
“Acoustics and architecture are directly linked with each other. Although sound is not visible, the geometry of a room and its acoustic characteristics are intrinsically coupled. This connection between aesthetics and acoustics provided the point of departure for our team to create beautiful acoustic panels that are specifically designed to give rooms a pleasant and soft feeling,” said Prof. Matthias Kohler at Gramazio Kohler Research, ETH Zurich. “We are thrilled to work with Aectual as they bring our designs to life.”

Designed to naturally mitigate noise and reduce reverberation and echo
The novel acoustic diffusion panels are for use in both commercial and residential spaces and naturally balance out the sound in any room by mitigating noise and reducing reverberation and echo. Made from a plant-based plastic, the diffusion panels are mass customizable and made-to-measure for every space and are designed to bring more comfort to commercial buildings such as hotel lobbies, libraries, offices, and shopping malls, as well as private homes and apartments. The design platform allows the adaptation of surfaces to individual room shapes and Aectual clients can personalize the acoustic diffusion panels to their unique taste. For large projects (greater than 100m2 / 1000 square feet), a tailored soundscript is created based on the spatial design of the room. Private homeowners can merge aesthetics and acoustics by easily attaching the panels to any wall.
Spatial acoustics are typically improved in one of two ways: by dampening or by diffusing methods. Aectual’s panels utilize the diffusion approach to soften the edges of hard sounds. The Gramazio Kohler Research team explored the combination of digital aesthetic parameters with acoustic performance. The result is a unique parametric design script that generates an elegant, undulating surface that disperses sound waves. Aectual’s acoustic diffusion panels are just as pleasing to the eye as they are to the ear — visually mimicking the infinitely changing landscape of waves, rhythmically moving but never the same. The panels absorb no less than 50% of the reflected sound waves in various spectra.

Produced waste-free and 100% circular
Aectual’s 3D-printing additive manufacturing process is entirely waste-free and a majority of Aectual’s products utilize circular plant-based plastics. After use, Aectual takes back the building products and directly recycles and reprints them into new products. Depending on the product type, this results in a 35% to 95% material reduction due to its parametric designs, amount of materials needed, special manufacturing and product design optimization. The process - Aectual Circular - is a novel circular design and digital production service that allows products made by Aectual to be easily shape-shifted from one material into infinite interior design solutions up to seven times.
“Our collaboration with Gramazio Kohler Research ETH demonstrates Aectual’s ambition to bring together academic research and innovative designs to a wide audience, by offering designers and academia a single platform to publish, manufacture, and directly share and sell their designs” Hedwig Heinsman, co-founder Aectual
“Aectual’s founding mission is to provide 100% circular, on-demand, smart design solutions that make use of digital design and digital manufacturing. Our collaboration with Gramazio Kohler Research ETH demonstrates Aectual’s ambition to bring together academic research and innovative designs to a wide audience, by offering designers and academia a single platform to publish, manufacture, and directly share and sell their designs,” said Aectual co-founder and Chief Commercial Officer, Hedwig Heinsman.
From artisan wall piece to custom immersive panel system
Aectual’s panels can be directly purchased via the webshop at or personalized to the buyer’s exact taste. Architects and clients can also choose to create their own made-to-measure project solutions via the architecture section. The panels are available in a standard Velvet Grey color or in any Natural Color System ® (NCS) color upon request.
