Abstract

The main aim of the study is to propose new personalized 3D designed elbow orthoses and new ankle-foot orthoses using reverse engineering and rapid prototyping. A general reverse engineering procedure was used including: data acquisition, preprocessing, contours and surface fitting and CAD model creation. Mituyoto CMM machine and Hymarc Laser Scanning system were used for scanning data acquisition. Different scanning angles were used to cover all the scanning points representing the human upper limb and the ankle-foot complex. The point cloud data were obtained. Preprocessing was used in order to remove the redundant point data and noises and to reconstruct the point cloud data into "optimal" data for CAD modelling. CopyCAD software was used for pre-processing the scanning data and for contours and surface fitting. Based on the contours representing arm and ankle-foot geometry, surface and solid models were constructed in CAD/CAM modelling packages such as ProEngineer and UG. Error analysis was used to estimate the differences between the CAD models and the original point cloud data. ProEngineer were used to design the new orthotic devices. Wax print models of the upper limb and ankle-foot Complex were obtained, laser scanned, CAD reconstructed and compared to the direct scanned CAD models. Different polymers versions of new devices were manufactured using rapid prototyping. Prototypes of new orthotic devices were obtained and analyzed.
