Literally as soon as I started playing shakuhachi ~20 years ago I started thinking about 3d printing them, but hadn't taken any real steps in that direction until recently. David Brown, who makes the finest shakuhachi I have ever played, has been kind enough to share his expertise, measurements, and techniques with me, and a couple months ago I started working on a set of programmatically-modeled shakuhachi. My 3d printer is still in shipping limbo, but due to a friend's generosity I have one!
There are refinements to be made before it is a real professional-quality instrument, but I feel like the approach has been validated and I now have little doubt that it's an achievable goal. For the most part this one plays in tune and with excellent tone, which the crappy webcam mic doesn't really let you hear. But so exciting....
@jjb What about them makes them tempting to 3D print? Can you tune the sound in a way you can’t with traditional fabrication?
@aneel detail in the bore shape produces desirable tone characteristics and is machinable with traditional methods but it's a giant PITA and tiny (sub-mm) features can be butterfly wings and change the sound.
