3D-Printed Front Limb Wheelchair for Medium-Sized Dogs with Mobility Disabilities

The design and manufacturing of a 3D-printed front limb wheelchair for dogs with congenital malformations are presented in this paper. CAD design techniques and additive manufacturing using PLA and TPU materials were employed to create a modular and adjustable structure that enhances mobility and provides physical assistance. The proposed solution was specifically developed for Kangu, a medium-sized dog with a congenital malformation in its front legs. The wheelchair incorporates a three-point support system with height and angle modulation mechanisms to ensure enhanced stability and comfort based on the dog’s anatomical characteristics and test evaluations. Evaluation results demonstrate a significant improvement in mobility, facilitating independent movement and rehabilitation. This study highlights the potential of 3D-printed assistive devices in veterinary applications, emphasizing the importance of customizable solutions to improve the quality of life for animals with mobility impairments.
