Angklung

prusaprinters

The Angklung is an Indonesian music instrument traditionally made from bamboo. This simplified version only has one resonating tube per pitch, but still works well. For each pitch, a resonator, stand, and striker will need to be printed. I used superglue to attach the striker to the stand just below the curve in the resonator.For different pitches, use the same .stl files but modify the print scale in your slicer. The lowest pitch in the sample video below was scaled to 120% of the file size and is C#4 (albeit in A≠440). Sadly I don't have a larger printer to try resonators larger than 210mm, so I couldn't get the fundamental pitch down to that tyrannical C. The other pitches in the video below were printed at 100%, 96%, and 90%, and were E4, F#4, and G#4 respectively. For additional pitches, just progress through the harmonic series and you should have access to a full scale, (using ratios of 1:2, 2:3, 3:4, 4:5, etc).To make music, you could print out several different pitches and assign people to rattle specific ones at specific times like a handbell choir does, or you could hang them from a dowel or string and try to play a tune yourself. Here's a short, admittedly non-musical, sampling of how it sounds. Angklung really shine when you have a lot of them playing simultaneously though. Here's what that can sound sound like… For what it's worth, the prints used in the sample video were printed with PLA at 20% infill with 0.2 mm layer height. I tried the striker at 100%, but didn't really hear a difference.If anybody actually prints and uses these, please share your work!
