We support museums, research institutions and companies in planning, execution, and post-processing of 3D imaging for cultural heritage objects.

We are currently working on 3D imaging of six historic bassoons for the Schola Cantorum Basiliensis (University of Applied Sciences and Arts Northwestern Switzerland). The project includes the implementation of high-resolution CT scans, post-processing of the data to make the models printable, and 3D printing of the metal keys from brass. More on that soon.

We produced a playable replica of a 15th century bone flute for the Musikinstrumentensammlung Willisau, Switzerland. The flute block is not preserved, therefore the original instrument does not produce sound. In the course of our work we performed a high resolution X-ray computed tomography, designed a variety of new blocks as CAD models, tested them with a fluid dynamic simulation, and printed a playable replication.
The slides for a lecture on the subject that we recently gave at the Cité de la musique in Paris can be found here.

Scans of instruments like violins and viols can be represented as high-quality images.
A spatial resolution of 100 µm voxel size allows for the examination of all structural elements.
Even minuscule details, like tool marks, vestiges of prior repairs, and micro cracks can be rendered visible.
Thickness measurements can be performed with high precision.
The cross sections of the soundboard can be used for dendrochronological dating.
By extracting the surface, the data set can be used for the replication of all individual parts of the instrument using 3D-printing or CNC-milling with an accuracy of max. 0.1 mm deviation.
Even wood density can be determined for all parts.
In the volume rendering of the soundboard a horizontal reinforcement of the bass bar is clearly visible.
The cross section at this position shows that it caused a flat deformation of the arching.
It might be considered to remove this part in order to correct the arching.
The other reinforcements and the soundpost patch in the back can be examined as well.
