RESEARCHES ON USING ABS COMPOSITE AND SILICONE TO BUILD INSOLES BY 3D PRINTING

Abstract

The insole used for medical purposes are the constructive variants with good efficiency in posture recovery procedures and the quality of human subjects' walking. In this paper, the variants of the insole that allow the obtaining of correct posts in different activities, but also the ways of realization from different materials are analyzed. In the first part of the paper, the theoretical aspects regarding the configuration and the structure of an insole, followed by the experimental considerations regarding the testing of the forms of the insole under the effect of the different conditions of use are presented. From the conclusions of these analyzes, it has been possible to use rigid support insole made by 3D printing, to which is added a flexible silicone structure with a protective and effective purpose for the uniform distribution of forces on the plantar surface. Measurement of this distribution has been achieved by means of pressure sensors embedded in the insole structure and displaying values on a computer. In the final part of the paper, the results and conclusions of these tests are presented.
