Abstract

Orthotic footwear requires a comfortable design to solve biomechanical foot issues such as walking, standing or running of the patients. In this case, the accurate geometrical data are needed by applying a 3D scanner. However, geometrical deviations of the final product may be often found in the manufacturing process related to the system or changing the CAD data format. The purpose of this research was to investigate the effect of the data transfer process on the geometry and morphology of the foot scanning results. Firstly, variations in data format from the patient's foot were obtained using 3D scanning with Handyscan 700 scanner, Einscan Pro 2X Plus, ScanPod 3D and photogrammetry method with a Canon EOS 500D camera. The second step involved the data transfer to the CAD modeller using Solidworks software. The results showed that the geometry and morphology of the scans from each scanner were indifferent and the variation of CAD data formats did not affect the geometry and morphology. In CAD software, the very large CAD data format is IGES, the result of a Handyscan 700 scanner with a file size of 38,864 KB. The smallest data format is the STL on the ScanPod 3D scan results of 671 KB.
