This research presents a small-scale, desktop educational proof-of-concept prototype of a voice-controlled and 3D (three-dimensional)-printed dental chair model designed to improve the clinical work environment by reducing direct manual interaction. The system integrates a microcontroller, four servo motors, and a smartphone application, enabling touchless chair position changes via predefined voice commands. Ten functional chair positions are developed, ranging from 0° to 90° for four chair situations. The mechanical model is designed in SolidWorks, and a 3D-printed model is generated to visualize the actual chair. The system is evaluated through practical tests, which demonstrate an average execution accuracy of 84% across all voice commands. The system is under development and operates in both Arabic and English, making it available to local and international users. Future proposals include advanced voice recognition models and noise-filtering techniques, with the scope of application expanding to encompass variations in voice tone and accents across users.
