In this project we will reverse engineer a mystical part of the saxophone: the mouthpiece. Focused on optimizing the acoustic properties, this includes making CT-scans, parametric modeling and high-grade metal printing. You will autonomously contact several experts and well known (jazz)musicians. Experience with reed or woodwind instruments is preferred! (Expert: Zjenja Doubrovski)

Scanning results

Thursday October 6

Today the exciting moment was arrived to look at the final scanning results of our two mouthpieces. Luuk and I met ing. W.Verwaal at the restricted scanning area of the building of Civil Engineering. Mr Verwaal had tried very hard to retrieve a good picture of the metal mouthpiece as well as the mouthpiece of hard rubber. Unfortunately, the metal mouthpiece was very hard to scan. A lot of the x-ray beams were reflected by the material, or could not penetrate the metal. To improve the results mr. Verwaal tried to scan the mouthpiece in the Siemens medical scanner, but the results still were not up to our hopefull expectations.

As you can see, the picture is rather blurry. Mr. Verwaal is a persistent person, so he will try to make another scan, but he is not expecting it to be better.
The mouthpiece of hard rubber however, has not been such a problem. The beauty of the pictures struck us with amazement, and also mr. Verwaal was pleased with these results.

In the picture above, you can see different views of the mouthpiece. As you can see in the 3D picture, the text "meyer" is shown on the mouthpiece. None of us could remember this text on the real mouthpiece, but perhaps we were not so alert Tuesday to notice the text.
Mr. Verwaal gave us an enormous amount of data, including 800 pictures of the mouthpiece, from different angles. We now can try to obtain the required software, to actually measure distances of the mouthpiece.
The visit to the x-ray scanner has been very pleasant and informative, thanks to mr. Verwaal.
