Abstract
Three-dimensional (3D) printing is one of the advanced sustainable manufacturing techniques for the production of composite structures for engineering applications. The objects that are printed using 3D printing technique can be produced with lighter weight as compared to traditional manufacturing methods. Improved mechanical properties can be achieved with 3D printing techniques by selecting a suitable combination of fibre along with polymeric material. In this work, PLA (polylactic acid) was reinforced with the glass fibre to prepare sandwich composite as per ASTM D638 type IV standard for tensile testing. The input parameters varied for sample preparation are infill density (50%, 75%, 100%), infill linear sample, number of glass fibre layers (1, 3, 5) and nozzle temperature (210 °C, 215 °C, 220 °C). The effect of variation of these parameters on tensile properties was studied. In sample 3 (single GF layer with 100% infill density and 220 °C infill temperature), the maximum peak and breakpoint strength were observed.
