Results

Results may be imported and viewed in the Simulation Utility for Netfabb or ParaView. Figure 1 shows the results of each of the 2 substrate thermal simulations and Figure 2 shows the results of each of the 2 powder sintering thermal simulations, each during the simulation of the second laser scan.

The substrate heating simulations both model the thermal behavior during moving heat source based pre-heating. Using the fixed autogenerated mesh shown in Figure 1 (a) produces a fine mesh in the regions of heating. The adaptive mesh shows only fine mesh around the heat source at the individual time increment in Figure 1 (b).

Powder sintering without modeling the powder is shown in Figure 2 (a) while the simulation including the powder is shown in Figure 2 (b).
