Influence of Layer Thickness on the Tensile Properties of the Samples Manufactured by Fused Deposition Modelling

Nowadays, while fused deposition modelling (FDM) process is one of the most commonly-used additive manufacturing (AM) techniques due to its ability to manufacture very complex geometries, the major research issues have been focused on striking a balance between visual aesthetics and performance of the products manufactured by this method. In this study the effect of layer thickness on the tensile properties of poly lactic acid (PLA) samples were investigated. The results showed that the tensile strength and young modulus of the specimens decreased with the increase in layer thickness. Significant reduction of mechanical properties was obtained for the samples printed with 400μm layer thickness
