With the Indirect Metal Laser Sintering and by means of a heat treatment in an oven process
metal components can be produced. In the first step the polymer is transformed from the solid
state into the gas phase. This takes place all over the component at different velocities depending
on the local temperatures and temperature gradients. The creation of the gas phase develops a
pressure inside of the component because the diffusion of the polymer within the part has a finite
velocity. The pressure may contribute to a damage of the component. This essay deals with the
procedure to simulate the gas pressure on the basis of the implementation of kinetic models in the
