FABRICATION OF AUTO STABILIZING SPOON USING 3D PRINTER

Abstract

This research focuses on the development of an Auto Stabilizing Spoon, a low-cost, self- stabilizing assistive device designed to help individuals with hand tremors eat more easily and independently. Hand tremors, often associated with neurological conditions such as Parkinson’s disease and essential tremor, significantly hinder daily activities like eating, impacting quality of life and dignity. The primary objective of this project is to minimize food spillage during consumption, thereby improving the eating experience for affected individuals. To achieve this, the spoon was designed using advanced 3D modeling software, which allowed precise customization of dimensions and mechanical features to accommodate the specific needs of users. The prototype was manufactured through Fused Deposition Modeling (FDM) 3D printing technology using PLA filament. This method was selected due to its advantages in producing lightweight, durable, and cost-effective prototypes, while also offering ease of iteration for future design improvements. After fabrication, the prototype underwent functional testing with a patient diagnosed with hand tremors. The tests focused on evaluating the spoon’s ability to stabilize against involuntary hand movements during eating activities. Results demonstrated that the Auto Stabilizing Spoon effectively reduced food spillage and enhanced the patient’s ability to eat independently. The findings suggest that this design offers a promising, affordable solution for individuals with tremor-related disabilities. Future work will focus on refining the stabilization mechanism, integrating smart sensors for adaptive control, and expanding the design to other eating utensils to further support independent living among patients with motor impairments.
