Experimental Investigation on Influence of Infill Density on Tensile Mechanical Properties of Different FDM 3D Printed Materials

Abstract

One of the advantages of FDM technology is the production of product materials with infill structure. In order to make the most of this advantage, the behaviour of FDM printed material with infill structure under different loads has to be analyzed and understood. Therefore, the goal of this experimental research is to analyze influence of infill density (100%, 80%, 60% and 20%) on tensile mechanical properties (tensile strength and elastic modulus) of PLA antibacterial nanocomposite, tough PLA and ABS-X 3D printed materials.
