TU Delft and Materialise Upgrade Acoustics with AM’s Freedom of Design
We’ve all been there — experiencing the unpleasant, loud noises that come with large, open, multi-use spaces. This discomfort is amplified by specific, irritating frequencies. Sometimes it feels as if you can’t even hear yourself think.
It’s to solve this issue that the architecture department at TU Delft turned to the help of a user committee consisting of companies from multiple industries, including Materialise for additive manufacturing (AM). Together, the team worked on a research project funded by Netherlands Organization for Scientific Research to develop a solution that improves the acoustics in these areas, such as concert halls or sports arenas, to enhance visitors’ auditory experiences.
In order to create this solution, the TU Delft team wanted to create panels that could be placed inside rooms where this level of noise is reached to block these bothersome frequencies and echoes. They knew they wanted to achieve this acoustic advancement with expertise from various industries, so Materialise stepped in to help with the manufacturing aspect.
As 3D printing experts, we are there to empower our customers to build their solutions. When we work with others in collaborations such as this one, it’s our mission to ensure that the project incorporates the full value of AM to accomplish its goal.

Incorporating AM’s full value
For this project, the TU Delft team chose 3D printing as the manufacturing method because of its freedom of design. They wanted a dynamic structure with organic geometries that not only targeted bothersome frequencies but were also aesthetically pleasing.
“We use additive manufacturing because of its potential to produce a large variety of complex shapes,” explains Michela Turrin, Associate Professor of Design Informatics at TU Delft. “It gives a lot of freedom in the complexity of the geometry, but it also enables production to be made in unique pieces that are not necessarily based on industrial repetition.”
3D printing isn’t held back by the same constraints as traditional manufacturing methods, such as limited shape possibilities which require extensive assembly. With the digital design files, Laser Sintering was a cost-effective way to create puzzle piece-like parts that could later be assembled quickly and easily to construct the panel — all while maintaining an attractive appearance.
At Materialise, we’re always open to co-create, and when projects such as this come our way, we are happy to share our expertise, collaborate on new solutions, and learn together.
