Load Capacity of a Gyroid Structure Produced by Selective Laser Melting

Abstract

The quest for light and stiff structures by industries such as the medical industry and the aerospace industry is the driving force behind developments in additive manufacturing technology. One way to achieve significant weight reduction of components is by deploying periodic porous structures. Various types of porous structure geometries use material with varying efficiency, and therefore vary in their resulting mechanical and physical properties. This article focuses on the lightweight Schoen Gyroid cellular structure, which could offer a suitable combination of the desired mechanical properties. The goal is to determine the effect of the volume fraction on the load capacity of the gyroid structure made of maraging steel using DMLS technology. We conclude from the experimental measurements that the results could be affected by several factors, which are detailed at the end of article.
