Case Study Palousek et al. (2014) describes the case study of wrist orthosis design process. The whole manufacturing methodology of the case study covers five main steps (Figure 13): • Data acquisition of the upper limb – one side geometry, • Polygonal data processing, • Parametric surface generating, • CAD design process, • RP of the orthosis, • Surface finishing, coloring and • Testing. Figure 13 Design process of the upper limb orthosis Data acquisition Scanning was performed with a di3D FCS-100 photograph scanner from Dimensional Imaging. This FCS-100 checking framework is particularly intended to catch 3D surface pictures of human appearances or the entire body. It utilizes four 10 megapixel cameras to make 3D models with exceptionally point by point surface maps (a determination of up to 21 megapixels). All photographs are caught at one minute and the model is then made in no time flat. The digitized geometry of the limb surface was saved in a polygonal STL format (48,058 focuses, 94,763 polygons). The need of just a single scan amid the scanning strategy was exploited, on the grounds that the plan of the orthosis is like the outline of a traditional orthosis, one side type, there was no compelling reason to filter an limb from numerous sides to get finish output of the limb, which extraordinarily quickens and streamlines the entire procedure. Then again, this procedure is significantly more confounded where the…show more content…
This RP innovation has been utilized as a Direct Digital Manufacturing as in the printed display was utilized as the final product. For the formation of the orthosis model, 66 cm3 of ABS display material and 77 cm3 of help material were utilized, the building time was 9.5 hours, while the height of the layer was 0.25mm.
