Printing temperature effects on the structural and mechanical performances of 3D printed Poly-(phenylene sulfide) material

Abstract Fused Deposition Modeling (FDM) is the most popular and widely used additive manufacturing techniques for plastic materials. In FDM, the Z-height of the object is achieved by depositing extruded polymer layer upon layer. To reduce the time and cost of printed parts requiring specific properties, many processing parameters can be adjusted to optimize the FDM process. Among those is the nozzle temperature. In this study, Poly-(phenylene sulfide) (PPS) was chosen because of its mechanical performance, making it attractive for high-performance applications. In this work, the impact of printing temperature on the mechanical and structural properties of printed parts was carefully tested. Results show that a 340°C printing temperature yield the parts with the highest tensile properties, with a degree of crystallinity superior to as-received PPS.
