Tensile behaviour of a 3D printed lattice structure

Abstract

An additive technology can produce complex geometries which might not have been possible to produce using traditional manufacturing techniques. One such geometry is a lattice structure that can lighten the core of a component. The article deals with the investigation of tensile properties of the samples made from ABS (Acrylonitrile Butadiene Styrene) material. Two types of cylindrical lightened samples (with a simple lattice structure and in the form of a tube) were analyzed experimentally. FDM (Fused Deposition modelling) technique and filament of a 1.7 mm diameter were selected for the samples production. The results showed that at almost the same cross-section area of the samples, the lattice structure can carry a higher tensile yield strength compared with a shelled tube sample. © 2020 IEEE.
