| 總結: | A two dimensional finite element model was applied to determine temperature distribution within the layer block in the Selective Laser Sintering (SLS) of polycarbonate powders. Temperature time history and the sintering densification within the powder bed have been assumed to follow the solution of the heat conduction and the Nelson model (1993), respectively. The conductivity and the specific heat of the particle bed are treated as a function of temperature. In this model, shrinkage which usually occured after cooling is not considered. The results show that densification depends on the temperature distribution within the powder block and the laser power or the Andrew number. |
