| 概要 |
Additive manufacturing, particularly 3D printing, and computer-aided design (CAD) have been instrumental in recent advances in prostheses. This work focuses on using 3D printing to make personalized p...rosthetic limbs, especially for pediatric applications. Although the future looks bright, a lack of clinical proof and technical details prevents wider use. This study examines user input, 3D printing procedures, and design complexity, emphasising both durability issues and useful advantages. Using bio-inspired design in 3D-printed upper-limb prosthetics, particularly hand prostheses, is a major area of focus. An innovative prosthetic hand with movable fingers was created by imitating the structure of human fingers. These prototypes demonstrated enhanced grasp adaptability and produced superior pinch force, providing reasonably priced and lightweight alternatives. In this study, three irregular-shaped objects have been tested to measure the grasping force, with the properties of each object being detailed, including several fingers used to grasp the irregular objects. The study concluded that the average total grasping force required to grasp irregular objects for 54 g of puzzle pieces is 0.514 N, for 107 g of books is 0.726 N and 3 g of balls is 0.694 N are the outcomes of the grasping.続きを見る
