Background:

Patient-specific vocal tract replicas are valuable for research and education.
Current methods for fabricating these models are often challenging and costly.
There is a need for more accessible and efficient fabrication techniques.

Purpose of the Study:

To detail an accessible method for fabricating transparent, patient-specific vocal tract models.
To improve upon existing vocal tract model fabrication processes.
To enhance the availability of these models for research and education.

Main Methods:

Digital reconstruction of patient-specific vocal tract geometry.
Fabrication of a vocal tract mold using three-dimensional (3D) printing.
Casting transparent silicone material around the 3D-printed mold.
Removal of the mold to create a hollow vocal tract replica.

Main Results:

A combination of 3D printing and silicone casting successfully produced transparent, patient-specific vocal tract replicas.
The developed method offers improvements in consistency, reduced labor, and lower production costs compared to previous techniques.
The resulting casts accurately represent the intricate geometry of the vocal tract.

Conclusions:

The described method provides a practical and cost-effective approach to fabricating transparent vocal tract models.
This accessible technique can significantly increase the availability of patient-specific vocal tract replicas for scientific and educational applications.
Further modifications may expand the utility of this fabrication method for diverse research needs.
