Application of Reverse Engineering in the Manufacture of Prototypes of Mechanical Parts

Abstract

This paper presents the study of reverse engineering and three-dimensional printing as an alternative in the design of automotive parts, taking as a case study the distribution cover of the 2015 Chevrolet Spark car. For this, a 3D scanner “Scanner Handy” was used Scan” to capture the shape and characteristics of the distribution cover, and obtain a three-dimensional mesh (point cloud) for analysis, which is processed by using the “Geomagic Desing” software to obtain the three-dimensional CAD model; This model is imported into Siemens NX software to make dimensional adjustments through a comparative analysis between the constructed CAD model and the copied element, to perform prototyping by 3D printing. Finally, as a result, a prototype of the Spark 2015 distribution cover is obtained with the respective valuation of its mechanical properties, and an analysis of the degree of feasibility of this manufacturing process in the manufacture of automotive parts by means of 3D printing “FDM”.
