The CFD model validation is crucial to validate the simulation results. Minimum
measurement error (i.e., 4.2%) was observed between the numerical and average
experimental values.
5 Conclusion
The temperature distribution over the cured surfaces, heated at 60 °C using a ceramic
infrared-based fast heating system, was investigated by experimental measurement
and thermal module of ANSYS simulation. Based on the simulation result, a uniform
temperature of 57.22 °C was observed on the upper surface of the model and was
gradually reduced from the upper surface to the lower surface. Furthermore, the
temperature distribution on the top surface of the cured part was measured with
a high-resolution thermal camera, and the measured values agreed well with the
simulation results. Therefore, the experimental and simulation results clearly show
that the FTE serious ceramic infrared heater is feasible to heat the printed slurry with
almost the targeted (i.e., 60 °C) temperature during the curing process.
