Abstract
Prosthetic limb technology has advanced dramatically over the past two decades, driven by innovations in additive manufacturing, biomimetic design, actuation systems, and control algorithms. 3D printing has emerged as a disruptive technology enabling customized, lightweight, and cost-effective prostheses. Meanwhile, hydraulic mechanisms offer robust and adaptable actuation, especially in weight-bearing joints such as knees and ankles. This research explores the integration of 3D printed prosthetic limbs with embedded hydraulic actuation systems, assessing design optimization, fabrication processes, mechanical performance, and real-world applicability.
The research presents a novel framework for the design and implementation of a lower-limb prosthetic with a hydraulic actuation mechanism optimized via topology optimization and additive manufacturing. The study includes a detailed literature review, system design methodology, 3D printing parameters, hydraulic integration, performance testing, and discussion of results. Findings indicate that the integration enhances load response, durability, and gait adaptability compared to traditional prosthetics. Recommendations for future work include improved sensor-feedback systems and liquid cooling for enhanced hydraulic performance.
The prototype demonstrated significant improvements in energy efficiency during simulated walking cycles. Additionally, the additive manufacturing process allowed for rapid prototyping and customization tailored to individual user needs. These advancements suggest a promising direction for future prosthetic development focused on both functionality and user comfort.
