Material Properties Of 3D Printed Parts: Challenges In Design And Analysis

The present paper addresses the challenges in design and analysis of 3D printed structures with anisotropic material properties. In recent years the additive manufacturing technologies have been used in most of the industries because of their freedom in fabrication of any complex geometry part. However, the final properties of the 3D printed parts are anisotropic though the material used is isotropic. Further, the properties of printed part are not homogeneous. This change in the properties is due to process parameters and build orientation of the parts. Therefore, this calls special attention of the designer for effective design and analysis of such parts. In this paper, design consideration of the parts for 3D printing and also, their structural analysis for effective design of parts for 3D printing are discussed. Further, different steps involved from design to 3D printing of a product are discussed.
