Design, Fabrication, and Evaluation of a 3D printable locking mechanism for 3D printed transradial hand prosthesis suitable for developing countries

An AM optimised transradial interface for low-income countries

Prosthetic devices remain inaccessible for many amputees in low-income countries. The lack of trained professionals and resources to fit a prosthetic (interface) are principle reasons. The low cost at which additive manufacturing technology (AM) is able to produce a custom made part could change this. As such, the aim of this study was to design...

A BIO-INSPIRED FINGERTIP: 3D Printed Surface Patterns and Their Role in Surface Friction: An Experimental Study

In the field of prostheses, significant developments have been accomplished so far in low-cost prosthetic limbs using 3D printing technology. However, when it comes to prosthetic hands, 3D printed prosthetic hands are still limited in their grasping ability, such as the adaptability to the shape of an object and a sufficient pinch force level...

3D Printed Hydraulic Actuation: Design and Evaluation of a 3D Printed Hydraulic Actuation System

Objective: The objective of this study was to develop and evaluate a 3D printed hydraulic actuation system, applied in a multi-articulate upper limp prosthesis. The prosthesis was designed to produce sufficient pinch force to be competitive with comparable devices (30 N), and weigh less than a human hand (<0.43 kg). The actuator should...
