text: One barrier of laser sintering (LS) to become the main process for Direct
Manufacturing (DM) is the surface quality of LS parts. Hence, the property which
has to be improved is the rough surfaces of LS parts due to the layered structure.
Another additional effect is the incomplete melting of powder particles on the
surface due to the high process temperature. In this paper we demonstrate our
approach of a theoretical model for the topography of LS part surfaces. We investigated
the surface roughness as a function of surface orientation. Considering that the
model involves further variables as layer thickness, particle density and particle
size distribution to describe the topography precisely. Experimental results were
used to optimize and check the results of the model.
