The foundation

The main goal of OpenBrass is to create a free software generating 3D models of brass music instruments, based on simple choices.

These 3D models can then be used with any manufacture using these « digital patterns », whether it is in metal or to test prototypes with a 3D printers as it is done in this fundation.

Assembly and tests

Fundamentals for musicians

On internet, we can already find several instruments that can more or less be played. These are usually not very documented and with random quality and sound.
Without any knowledge in the theory or without experimenting, it is a difficult thing for a musician to know which model to choose. Therefore, OpenBrass wants to gather together the ideas and to provide a reliable base for musicians.

Custom instruments

The customizable software if a major innovation that led to computer-aided design (CAD).
In a few clicks, we can now modify the properties of the instrument, adapt it to the needs and preferences of each, looking up to the accoustic criterias.
We can play with shapes and colors to integrate an other artistic field : visuals.

Why 3D printers?


For now, price estimates are :

-15€ for a B flat bugle, 24€ for a bass B flat bugle
-20€ for a E flat trumpet, 32€ for a bass E flat trumpet
-40€ for a B flat valve trumpet

These rates are based on the current cost of plastic which should fall over time.


ABS is 6-8 times lighter than metal!

A lighter instrument is ideal for both children and adults. For beginners a lighter weight makes it much easier to hold the instrument properly.

Not to mention that a lighter instrument is much more portable!


Small accidents that would dent a metal instrument will not harm a plastic model.

Even in the case of serious accident, the plastic is very strong and the sound quality of the instrument will not be harmed.

  Sound quality

The first prototype has a very centered sound, a reassuring quality for the future.

If you want to test the sound of this instrument by playing and comparing, the first prototype is visible in Nantes, FRANCE.

Please not hesitate to contact me!

  Form / Design / Color

3D printers are used to express creativity in shapes and colors.
Some designers have even mixtures of plastics??.

Example Recorder:

This means instruments are no longer limited to the classic gold or silver, though metallc paint can be applied to give a gold or silver appearance. The colors of the instruments could vary according to the wishes of the band, combing art and music!

  Growth of 3D printers

3D printers are still a very new technology even if they are already affordable to a wide audience.

3D printing will become more accurate, faster and less expensibe thanks to an active community.

Plastics are also being researched. There are already soft plastics, conductors, phosphorescent plastics, imitation wood and stone, ...

  Public Domain

The algorithms used to generate instruments, OpenSCAD files, STL files, and all other files will have CC0 licensing: donation to the public domain.


A donation from Open Brass allows this type of instruments to develop.

A forum will allow discussion amongst people interested in this topic, and their opinions will be considered.

Anyone can participate, advance the project or continue it. The aim is that it will be easy to continue the finished works.

For example, if someone suggested making a saxophone-shaped trumpet, I'd add it to my list of projects - it's that sort of innovative creation that I love to do!
