AN EDUCATIONAL APPLICATION OF 3D PRINTING TECHNIQUE USED FOR INSOLE PRODUCTION

Year 2016, Volume: 4 , 456 - 460, 01.09.2016

Abstract

In
this study, it was implemented a biomechanical application of 3D printing
technique for insole production. Basically, in terms of the arch height, there
are three foot types including high, normal and flat arch. Moreover, if the
alignment of the foot is taken into account, foot types can be classified as
neutral, supinated and pronated foot. Each foot class has different shape and
foot size. An insole is a device that is placed into the shoes to provide
comfort and to correct the alignment of the lower limbs. Design of the insoles
could be implemented according to specific foot geometry of subjects. These
kinds of insoles are called generally as customized insole and have
total-contact characteristics. Total-contact insoles are effective in reducing
pain as distributing the pressure and improving the foot function. To produce a
total-contact insole, the geometric data of foot plate surface should be known.
In order to carry out this task, molding process is widely performed. Advances
in scanning technology enable insole designers to obtain 3D CAD
(three-dimensional computer-aided-design) model which represents the shape and
dimensional data of an object. The model, namely, solid model could be imported
to various commercial or educational software and be modified for special
purposes. Therefore, molding process is discarded and molding cost is prevented
with the method of 3D scan. Many 3D scan devices exist to obtain 3D data that
may require high cost for an insole device. Thus, people even not having engineering
background could obtain 3D foot model using various free available image
capturing programs integrated in a mobile phone. In this educational
application, it is aimed to manufacture a customized full-contact insole by
means of a 3D printer and a 3D scan mobile application. The scanning software,
which combines the photos of the object captured from the different angles, was
used to obtain 3D CAD data of the geometrical shape of the foot in this study.
Then, the data was imported as a model to a CAD software and modified for a
subject shoe. Next, the model was converted into STL file format and imported
to a 3D printer device. Finally, the solid model of the insole was printed and
placed into the shoe. By taking advantage of new facilities of technological
improvements, subject specific insoles could be designed and manufactured.
These kinds of educational applications regarding 3D scanning and printing
technologies have the potential to increase the prevalence of use of custom
made biomechanical instruments which are developed to increase the quality of
daily life of human being.
