Simulation and Test of Transient Temperature of Selective Laser Sintering
|
Abstract:
3D transient temperature field of the selective laser sintering of Al2O3 tectorial ceramic powder was calculated real-timely according to finite element method based on the practical boundary condition and thermo physical parameters variation.The transient temperature was also tested using infrared thermo camera which its emission coefficient was corrected according to double-wavelength temperature measurement method.The result shows that the simulation agrees well with test result.
