Title 3D Shell Data Preprocessing Scheme for Additive Manufacturing
Abstract
The data processing of 3D part model is the key part in the manufacturing process of the material, efficient and precise realization of three-dimensional model of the quality testing, shear layer calculation is the important guarantee to ensure the stability of process control. This paper studied the selective laser melting (SLM) key technology material manufactured by data processing, first introduced the principle of the increase and development trend of material manufacturing, the SLM process in detail; secondly carried out a detailed study of the key technologies in data preprocessing, analyzes the common errors in STL documents and the reason for their causes, put forward corresponding measures for the restoration of the model were automatically repaired with Magics software; focus on slicing algorithm commonly used STL file, put forward a hierarchical ranking algorithm of triangle coordinate hierarchical and topological relationship based on, through the code, realize the calculation of the three-dimensional pressure shell model cutting layer, finally verify the feasibility of the algorithm.

1 绪论随着传统工业的发展乏力，信息化进程的加快以及全球化引发的激烈竞争。传统制造业势必迎来一场转型，制造业会逐渐缩短开发周期，降低开发成本，不断推出新产品以适应越来越激烈的竞争；除此以外，制造业还在向着个性化，多样化，小批量甚至单件生产方向发展，这就要求制造业同时拥有良好的开发、生产柔性。正是在这样的背景下，增材制造（Additive Manufacturing）得益产生并快速发展[1]。
