The Influence of Certain Operating Conditions of the FDM Process on the Mechanical Properties of Polymeric Materials—A Review

This M.Tech project provides research direction for investigating the intricate relationship between fused deposition modeling (FDM) process parameters and the resulting mechanical properties of polymeric materials. The increasing demand for high-performance polymeric components necessitates a thorough understanding of how FDM operating conditions influence material characteristics. This study emphasizes the critical role of process input factors in achieving desired mechanical attributes, such as tensile strength, compression strength, elongation at break, flexural strength, torsional strength, impact strength, fatigue resistance, and hardness. The project aims to synthesize existing research findings to establish a comprehensive framework for analyzing the impact of FDM variables on these properties. Furthermore, it explores various modeling and optimization methodologies

employed to predict and enhance the mechanical performance of 3D-printed polymeric parts. The research direction involves a systematic review and potential experimental validation or simulation of the identified correlations, offering guidance for structuring studies focused on optimizing FDM processes for superior material performance. This includes evaluating the influence of parameters like layer height, infill density, print speed, and nozzle temperature on the aforementioned mechanical properties, providing a foundation for advanced material design and additive manufacturing applications.
