Desenvolvimento de palmilhas ortopédicas utilizando metamateriais e manufatura aditiva

Abstract

The use of customized orthopedic insoles has grown significantly, driven by the need to provide comfort and efficiency in the treatment of orthopedic conditions. The objective of the study will be to develop orthopedic insoles using threedimensional (3D) technologies and metamaterials, aiming to offer customized solutions that meet the individual needs of each patient. Initially, a comprehensive literature review was carried out, exploring concepts related to the anatomy of the human foot, pathologies treated by orthopedic insoles, 3D technologies applied to the development of orthopedic devices and the use of metamaterials. Next, studies were conducted to assess the mechanical properties of the flexible materials most suitable for manufacturing insoles, using additive manufacturing (AM) techniques. Based on this data, digital models of the insoles will be developed using Computer Aided Design, Computer Aided Engineering and Computer Aided Manufacturing (CAD/CAE/CAM) systems, allowing precise customization according to the anatomical characteristics of each patient. CAE simulation was used to evaluate the performance of the insoles, considering the properties of the selected materials and the conditions of use. Finally, CAM planning was carried out for the manufacturing of the insoles using AM, followed by the physical production of the devices. It is expected that this research will contribute to advancements in the development of customized orthopedic devices, offering effective and comfortable solutions for patients with specific needs.
