The aim of this research study centers around the design and development, using a three-dimensional model of an ear-splint. This study results from the need of a non-invasive method, as the current techniques used in otoplasty have succeeded in reducing the risk of complications, but without drastically reducing the rate of postoperative deformity. Indeed, stick out ears present a deformity that occurs in 5% of the population. Factors such as psychosocial impact and intimidation lay the foundations for the need for such a method. This paper essays to create, through 3D printing, a case customized into the ear of any person of all ages. The splint was made on Zortrax M200 3D printer model, equipped with the V3 Hotend head, and the material used for printing was 16 grams of Z-FLEX. It is noted that the creation of the case is innovative and original. After putting the ear-splint into test, by applying it on a human ear, two conclusions emerge. First, it is very light, weight, just 16 grams, and second, it offers comfort and convenience to the user. In order to get results for its practicality, a clinical rehabilitation study is recommended.

“…D. Xia et al [7] performed numerical and analytical investigations to reduce the noise data properties for regions-of-interest (ROI), and reconstruct the images based on chord image reconstructions using different scanning configurations. S. Gauthier et al [8] proposed a method based on analyze and segment the digitized 3D surface mesh curvature histogram using a real object through detecting the peak and valley primitives, also proposed to use the curvature histogram analysis to measure the quality of mesh for a lot of reverse engineering steps, which could be used to construct the CAD model. C.

Abstract Although the rapid development in reverse engineering techniques, 3D laser scanners can be considered the modern technology used to digitize the 3D objects, but some troubles may be associate this process due to the environmental noises and limitation of the used scanners. So, in the present paper a data pre-processing algorithm has been proposed to obtain the necessary geometric features and mathematical representation of scanned object from its point cloud which obtained using 3D laser scanner (Matter and Form) through isolating the noised points. The proposed algorithm based on continuous calculations of chord angle between each adjacent pair of points in point cloud. A MATLAB program has been built to perform the proposed algorithm which implemented using a suggested case studies with cylinder and dome shape. The resulted point cloud from application the proposed algorithm and result of surface fitting for the case studies has been proved the proficiency of the proposed chord angle algorithm in pre-processing of data points and clean the point cloud, where the percent of data which was ignored as noisy data points according to proposed chord angle algorithm was arrived to (81.52%) and (75.01%)of total number of data points in point cloud for first and second case study respectively.

“…Kisztner et al introduced an algorithm based on image processing and remote sensing to create a software and procedure using cluster analysis and spectral behavior analysis to general use for vegetation separation from the 3D data cloud acquired by Terrestrial Laser Scanning [3]. Gauthier et al have proposed a method to analyze a histogram of curvature for an actual object using a digitized 3D surface, also propose using the analysis of the curvature histogram to retrieve a CAD model for many steps of a reverse engineering process [4]. Lee and Bo were suggested a smooth reconstructs feature curves approach and refine incident approximation planes from the 3D point cloud based on intersections of developable strip pairs and approximation of the point cloud as linear segments to collect the features of the curves [5].…”

Pre-processing is essential for processing the row data point clouds which acquired using a 3D laser scanner as a modern technique to digitize and reconstruct the surface of the 3D objects in reverse engineering applications. Due to the accuracy limitation of some 3D scanners and the environmental noise factors such as illumination and reflection, there are some noised data points associated with the row point clouds, so, in the present paper, a preprocessing algorithm has been proposed to determine and delete the unnecessary data as noised points and save the remaining data points for the surface reconstruction of 3D objects from its point clouds which acquired using the 3D laser scanner (Matter and Form). The proposed algorithm based on the assessment of tangent continuity as a geometrical feature and criteria for the contiguous points. A MATLAB software has been used to construct a program for the proposed point clouds pre-processing algorithm, the validity of the constructed program has been proved using geometrical case studies with different shapes. The application results of the proposed tangent algorithm and surface fitting process for the suggested case studies were proved the validity of the proposed algorithm for simplification of the point clouds, where the percent of noised data which removed according to the proposed tangent continuity algorithm which achieved a reduction of the total points to a percentage of (43.63%), and (32.01%) for the studied case studies, from the total number of data points in point cloud for first and second case study respectively.
