“…All the mechanical quantities in (9) are defined in terms of the internal time domain, ensuring the applicability of the property in Eq. (11) to the constitutive equations in (9), and therefore showing the fact that the TTS principle definitions for an SPC filament will remain the same as the matrix. In the Laplace domain, the symbolic homogenization problem reads…”

“…The FDM printing process induces a complex thermal history in the thermoplastic filament: from almost the material's melting temperature to room temperature. This severe thermo-mechanical loading creates significant defects in 3D-printed parts, commonly referred as warping [11], due to the creation of residual thermal internal stresses during the cooling of the polymer [50]. Currently, to estimate these internal stresses, finite element methods in commercial codes [29,28] solve the thermo-mechanical structural problem by integrating thermo-viscoelastic behavior laws for the polymer material [5,58].…”

“…El Moumen et al (2019) simulated the temperature distribution in the nozzle and the printed sample and evaluated the effect of temperature on residual stresses. Chen et al (2021) established a numerical simulation of the temperature profile and thermal stress field for FFF to predict sheet warpage. The simulation results indicated that serious sheet warping occurred when the infill line directions were aligned with the diagonal of the sheet.…”

Purpose Temperature is a critical factor in the fused filament fabrication (FFF) process, which affects the flow behavior and adhesion of the melted filament and the mechanical properties of the final object. Therefore, modeling and predicting temperature in FFF is crucial for achieving high-quality prints, repeatability, process control and failure prediction. This study aims to investigate the melt deposition and temperature profile in FFF both numerically and experimentally using different Acrylonitrile Butadiene Styrene single-strand specimens. The process parameters, including layer thickness, nozzle temperature and build platform temperature, were varied. Design/methodology/approach COMSOL Multiphysics software was used to perform numerical simulations of fluid flow and heat transfer for the printed strands. The polymer melt/air interface was tracked using the coupling of continuity equation, equation of motion and the level set equation, and the heat transfer equation was used to simulate the temperature distribution in the deposited strand. Findings The numerical results show that increasing the nozzle temperature or layer thickness leads to an increase in temperature at points close to the nozzle, but the bed temperature is the main determinant of the overall layer temperature in low-thickness strands. The experimental temperature profile of the deposited strand was measured using an infrared (IR) thermal imager to validate the numerical results. The comparison between simulation and observed temperature at different points showed that the numerical model accurately predicts heat transfer in the three-dimensional (3D) printing of a single-strand under different conditions. Finally, a parametric analysis was performed to investigate the effect of selected parameters on the thermal history of the printed strand.
