Development of modeling method for computational analysis of 3D printing model

초록

Additive manufacturing via 3D printing is a new processing technology that can be used in many areas to address the shortcomings of conventional cutting manufacturing. However, the dimensional accuracy of the output math data and the drawbacks of additive manufacturing, including differences in the material properties of the placement method, are among the issues that must be studied in the future. In this paper, several manufacturers of 3D printers that were widely used in the automotive industry were selected, and several output methods and materials were chosen among domestically produced printers. Based on the arrangement method, standard specimens were manufactured in compliance with ASTM, and the mechanical properties of each orthotropic material were measured. Then, based on the material, stiffness was quantitatively compared, and a volume reduction model was presented through an optimization analysis. Copyright © 2021 KSAE/184-07
