ABSTRACT

This study is aimed at developing manufacturing techniques for making orthotic devices using 3D printing technology to prevent previous problems that have been exposed from splint pan method. Infrared ray-based 3D scanning and conventional body size measurement process was conducted. Modeling and rendering tasks were performed using Autodesk 3DS Max program. We used NETFABB to save the data as a STL file and Creater K to control graphics and G-code transformation. Post processing and strapped process were carried out for final printed matter. Orthotic Checkout Examination for figure out the examination of devices and also usability evaluations. 4 fabricator made 5 types of orthosis using both methods. The results showed that the 3D printing technology method(23,400 kgf/㎠) indicated 3 times tensile strength stronger than conventional method (7,100kgf/㎠), but needed 730 minutes and 320,000won more than the other method. Fabricated with 3D printing technology for the orthosis could overcome previous problems and be the proper method to intervene and compensate with previous problems related to orthosis in Korea.
