Abstract

3D printing technology has undergone rapid development in the past few years and it is now possible to print engineering structures. This paper presents a study of the mechanical behavior of 3D printed structures using cementitious powder. Microscopic observation reveals that the 3D-printed products have a layered orthotropic microstructure, in which each layer consists of parallel strips. Compression and flexural tests were conducted to determine the mechanical properties and failure characteristics of such materials. The test results confirmed that the 3D-printed structures are laminated with apparent orthotropy. Based on the experimental results, a stress–strain relationship and a failure criterion based on the maximum stress criterion for orthotropic materials are proposed for 3D-printed structures. Finally, a finite element analysis was conducted for a 3D-printed shell structure, which shows that the printing direction has a significant influence on the load-bearing capacity of the structure.
