Pranathi Peri is developing a set of 3D printed, playable musical instruments for her summer internship. In her own words, she describes her design process:

Have you ever wanted to 3D print your own ukulele? Well now uke can! For the second instrument of my 3D printing internship, I decided to design and print a ukulele. After all, who didn’t trawl the internet looking for the best acoustic guitars under 300, and then end up with a ukele anyway because it was cheaper? They have such a charming aesthetic, and it’s that student living nostalgia that I wanted to try and tap back into. It also dramatically simplifies the process of choosing an acoustic guitar for your child, you can just print one instead now. Although, we have to admit, perhaps it won’t have the same charm.

The history of the good ol’ uke goes way back. During the late 1800s they were first introduced as instruments in Hawaii, where its name literally meant “jumping flea.” Well-known songs like I’m Yours, by Jason Mraz, Riptide, by Vance Joy, and Imagine, by John Lennon have familiar ukulele riffs which have contributed to the popularization of the instrument, yet these bands use the ukulele in maybe one to two of their songs, and then proceed to abandon it.

I know what you’re thinking; why would I want to design such an uncommonly played instrument?

Although the ukulele is not a widely sought-after instrument like the electric guitar, and piano, I decided to design and print it because it combines the aspects of many popular, commercialized instruments. For example, the ukulele is compact, like the violin, but is not as susceptible to external factors that may may warp the acoustics. It retains the same resonance as the acoustic guitar like the Yamaha FGX800c, but within a smaller body. It has strings that can be tuned, just like a piano, but rather than 236 strings, each with their own unique thickness and reverberation, it has 4 which are tuned to C, E, G, and A . For these reasons, and many more, I figured that a ukulele would be relatively easy to design and print, while still containing key aspects of various other basic instruments.

During the process of actually printing the ukulele, I learned many things about designing the instrument itself. One of which being, SAVE YOUR SOLIDWORKS MODELS EVERY 5 MINUTES. There is nothing more traumatic than losing a solidworks file which you had just finished after 1 solid week of work.
