As you can see, a lot of expertise is used to make a mouthpiece. The machines used eat away a lot of material, and you need to be extremely skilled to make a mouthpiece. Also, the machine has its limits in terms of amplitude and internal shapes it can cut away. Even when you have a machine that is completely automated and equipped with the most expensive drills, mills and other tools.
3D printing is very different from milling as with milling you remove material, and with 3D-printing you add material (additive technique).
Another thing that is completely different is that with 3D-printing, you can make shapes that you can’t make with a CNC machine, like cuts and edges.
In addition to this, with 3D-printing the credo is; when you can think about it and design it, you can probably print it! having said this, of course half of the work is the design part; countless hours have been spent on designing, prototyping, testing etc.
Designing a complex part like a mouthpiece requires skill. At deQuelery, we are doing this oursleves, just like the printing and finishing like setting up a facing and the curve of a mouthpiece. Even if you buy a mouthpiece off the shelve from a big company, it can still be useless when facing is not done correctly.
Finishing a part
Just lie with any other mouthpiece, we spend a lot of time finishing the part; we make sure the table is even and crrates a good seal with the reed, we make sure everything is symmetrical. The facing is the most imporant part, especially the start of the curve. This is all manual work. The idea that you can jsut print a mouthpiece and send it off to the customer is an illusion. When you’re interested in buying a 3D-printed mouthpiece, always ask the seller how they do their finishing and what facing or curve they apply. We always try to understand what the customer wants; not the other way around!
The material used for printing is very important. The raw material can be made from nylon, PLA (corn starch), ABS, PETG etc.. Food safety is key; always check what the raw material is and whether it is certified to be used. At deQuelery , we are making use of a special certified engineering PLA made from corn starch.
Adjusting a design to your needs is of course possible. We don’t promise you will sound like your all-time saxophone hero, but we will come close to the sound that you’ve always heard in your head.
Last but not least: ‘why is it called 3D-printing’? We don’t know to be honest, but then again what’s in a name? You know the basics now.

An example of how you can come to a product with a 3D print and parts of brass. The ligature is printed in 3D and designed by us.
One of our projects is designing and making clarinet barrels.
Are there any disadvantages? Yes, there are. 3D-printing a tenor mouthpiece does take 7 hours. This is just printing time. Another hour is needed to do the finishing and testing. In terms of material, we have found an excellent material that is hardened in an oven. This is called annealing. Right now, we have designed mouthpieces that play really well and sound just as good as any other!
We’ve done some endurance testing, and our PLA holds up fantastically well. With materials getting better and better, the charateristics will improve as well. The comment that we hear often is ‘it looks ok but hard rubber or metal is still what I would choose’. Fair enough, after all, 3D printed mouthpieces are made from some sort of plastic, which may give them a cheap appearance. Sure. Until you try them! Many musicians are very conservative and are afraid to try new things. That’s why new developments for the for example, the saxophone, come slowly. There’s lots more to develop and improve!
And in the years to come, more possibilities in 3D printing will see the light, like printing in metal – which is already happening and progressing fast! We’ll keep you posted!
