Abstract Scope |
This study explores the impact of thermal contact resistance on the mechanical properties of Fused Filament Fabrication (FFF) parts. A one-dimensional heat transfer model is developed to simulate a single road-width polycarbonate system. This model not only accounts for the influence of process variables on heat transfer within the structure but also incorporates experimentally measured environmental temperatures and thermal contact resistance values. The predicted tensile strength of the FFF part is then compared against models that neglect the effect of thermal contact resistance. The results demonstrate that, as layer deposition time increases, thermal contact resistance plays a more crucial role in determining the tensile strength. This highlights the importance of considering thermal contact resistance in modeling the mechanical properties of FFF parts. |
