Abstract Scope |
Fused filament fabrication (FFF) is a material extrusion additive manufacturing (AM) process that works well with thermoplastic polymers and is inexpensive compared to other AM processes, leading to its increasing popularity for industrial applications. With an accurate Finite element analysis (FEA) model, the FFF process can be simulated with various printing parameters, so the part can be manufactured under optimal conditions for improved mechanical performance. FEA is used here to simulate the thermal histories, among other properties, involved in FFF to estimate the extent of interlaminar bonding, or degree of fusion between two subsequent layers. Several simulation cases of increasing complexity are presented within MSC Digimat-AM, and both a thermocouple and an infrared thermal imaging system are used to validate the results from Digimat-AM. Validations results along with several insights into the FFF process are discussed. |
