Summary
Researchers developed embedded 3D printing to create multi-layer vocal fold models. This novel method offers a new way to study voice biomechanics and improve vocal fold model fabrication.
Area of Science:
- Biomechanics
- Bioengineering
- Acoustics
Background:
- Human voice production is often studied using silicone vocal fold models.
- Current models mimic in vivo vocal fold vibration but use multi-step casting processes.
Purpose of the Study:
- Introduce and demonstrate embedded 3D printing for fabricating multi-layer vocal fold models.
- Present a novel hybrid casting and 3D printing approach.
Main Methods:
- Fabrication process using embedded 3D printing described.
- Analysis of geometric and stiffness characteristics of model layers.
- Testing for sustained phonomimetic vibration.
Main Results:
- Successfully fabricated multi-layer vocal fold models.
- Layer elastic modulus ranged from <1 kPa to ~40 kPa.
- Models demonstrated sustained phonomimetic vibration.
Conclusions:
- Embedded 3D printing is a viable alternative for vocal fold model fabrication.
- This process can enhance voice biomechanics research.
- Potential for improved fabrication, design, and functionality of vocal fold models.
