This 3D-printed cello puts a carbon fiber spin on a classic

3D printing The days of simple plastic models are long gone. Today this technology is used to produce everything from whole houses And rocket partsTo microscopes and even food. After more than six years of experimentation and improvement, a former Yale student recently demonstrated another application: concert-worthy cellos and other stringed orchestral instruments 3D printed using carbon fiber.

The cello, created in the 16th century, is engineering marvel. His instantly recognizable, resonant melodies are only possible thanks to complex interaction types of wood, geometry, acoustics and physical characteristics of the player. Even the outer varnish is more than just an aesthetic choice: a thin layer is used to muffle the sound of the instrument without sacrificing its overall sound.

These factors also make cellos a serious financial investment. A decent entry-level instrument can easily cost over $600, while concert-grade examples typically cost musicians at least $15,000. Then there's upkeep and maintenance to consider. Without regular care, no amount of money can save a cracked frame or a deformed neck. Overall, logistical and financial barriers prevent many would-be musicians from ever pursuing this art form.

Elijah Lee, a cellist and Yale biomedical graduate, Forte3D wants to offer a new solution. His new company creates customized, customizable and durable 3D printed carbon fiber and polymer string instruments.

Lee first began experimenting with combining engineering and music when he was in high school. After learning about his love for 3D printing projects, his high school's band director suggested he try constructing a cello using the same techniques.

“It was gradual, but when we put together the first fully realized cello, I thought, 'Okay, wow, we really have something.' This moment was worth it.” – Lee stated in the university profile.

The Forte3D cello is not just a clone of a classic instrument. Instead, Lee and his colleagues modified the overall shape and form to take advantage of the unique properties of their materials. While a wooden cello body typically has a rounded top and back, the Forte3D version is based on flat, concave carbon fiber panels with a neck and ribs made from a 3D printed polymer. At the same time, vital components such as the bridge, sound post and fingerboard are still made of wood to provide familiar tone and acoustic presence. Thanks to the flexibility of visualization using CAD files, each individual tool can be further customized based on thickness, shape and material.

“Because we use our own designs… we can really tune the acoustics,” Lee explained.

After successfully selling on the show Shark TankLee is now moving forward with expanding the company to reach a wider audience, as well as introducing a wider range of tools. Forte3D already offers a 3D printed violin, and there are plans to add a viola and double bass to their lineup. Ultimately, Lee wants to expand the availability and durability of the tools.

“Music should not be limited by the price or fragility of wood,” he said. “A rural school student, a touring professional or an aspiring musician anywhere in the world could hold one [of these cellos] and feel the same richness, the same resonance, the same possibilities.”

At the moment, Forte3D prices are certainly not the cheapest. The 3D printed cello alone costs almost $3,000, and the violin costs almost $1,500. However, it is better than many classic options. With increased institutional support, it is easy to imagine the instruments one day appearing in schools and community music programs. Until then, the combination of art and engineering deserves a standing ovation in its own right.
