The allure of transformation captivates many, particularly those who remember the magic of seeing objects change before their eyes. Musician and maker Mattias Krantz taps into this fascination by creating a 3d-printed ukulele that evolves into a full-size guitar in an instant. His project, a feat inspired by childhood wonders and aimed at challenging musical perceptions, necessitated solving complex engineering puzzles.
3d-Printed Ukulele: Transforming a Vision into Reality
Krantz’s ambition was to create an instrument that defied expectations. Teaming up with mechanical engineer Adam Damato, they tackled the intricate challenge of extending a ukulele’s neck by roughly ten inches while maintaining string tension and expanding the body into a genuine guitar silhouette. This collaboration began with humor but evolved into an impressive display of design ingenuity.
Telescopic Engineering
The neck of this transformative instrument operates like a series of nesting parts, extending seamlessly from the ukulele’s frame. The telescopic neck locks into place, supported by a robust steel core that withstands the pressure of eighty pounds of string tension. Although the initial folding neck design failed, the telescopic version proved successful once reinforced with steel.
Innovative String Mechanism
The strings of the instrument, designed to be double the normal length, use a clever roller system that accommodates the stretching required during transformation. This mechanism prevents detuning by feeding slack when the neck extends and retracting it when shortened. Overcoming failed prototypes, this solution required custom-made strings that were worth the wait.
Expanding Body Dynamics
The body transformation is driven by six panels that extend independently from the ukulele, creating the curves of a full guitar. Achieving this involved replacing plastic components with metal, allowing for the precise movement of each panel. This transformation resolved earlier design issues, resulting in a stable and aesthetically pleasing instrument.
A Performance Worthy Transformation
Krantz’s invention transcended gimmickry when showcased in street performances. Its seamless transformation during live shows captured audiences, securing acclaim rather than skepticism. The sophisticated engineering—boasting steel joints and custom mechanisms—earned the project genuine respect and interest from both fellow musicians and the audience.
